     BACKGROUND 
     Dengue virus (DEW) is a major threat to global health, estimated to infect 400 million people annually in over 100 countries. The four serotypes of DENV (1-4) are transmitted by a mosquito vector. There are currently no approved antivirals available for dengue treatment. The majority of symptomatic patients present with dengue fever; a flu like illness. Five to twenty percent of these patients progress to severe dengue (SD), manifested by bleeding, plasma leakage, shock, organ failure, and sometimes death. Early administration of supportive care reduces mortality in patients with SD, however, there are no accurate means to predict which patients will progress to SD. The currently utilized warning signs to identify dengue patients at risk of progressing to severe disease are based on clinical parameters that appear late in the disease course and are neither sensitive nor specific. This promotes ineffective patient triage and resource allocation and continued morbidity and mortality. There are currently no biomarkers to effectively predict disease progression.

     A. Dengue Virus 
     Dengue (DENV) viruses belong to the flavivirus genus of the family Flaviviridae and are of four serotypes, DENV 1-4. Dengue viruses are positive strand RNA viruses which code for ten genes. The genes are translated as a polyprotein which is cleaved b host and viral proteinases. The DENV envelope glycoprotein (E) is the major surface-exposed DEW antigen and is a principal target against which neutralizing antibodies are directed. The three-dimensional structure of the E glycoprotein has been determined at 2 Å resolution for tick-borne encephalitis virus and recently for dengue type 2 virus (Rey, P. A. et al. (1995)  Nature  375:291-298, Modis, Y. et al. (2003)  Proc. Natl. Acad. USA  100:6986-6994 These studies showed that the monomeric E polypeptide is folded into three distinct domains and that the E glycoprotein consists of a flat, elongated dimer structure, with an interdomain ligand-binding pocket. The membrane protein also appears on the virion surface and is required for the proper processing of E. Dengue virus prM and E structural proteins and nonstructural NS1 protein are glycosylated. The prM glycoprotein is further cleaved by the cellular enzyme furin following viral assembly, generating M, which is present in the mature virus (Stadler, K. et al. (1997)  J. Virol.  71:8475-8481). Flavivirus prM and E form heterodimers, which are assembled into viral particles during infection (Wengler, G. and Wengler, G. (1989)  J. Virol.  63:2521-2526). In this manner, the prM serves to protect the functional integrity of E from acid-induced conformational change (Heinz, F. X. et al. 1994  Virology  198:109-117; Holzmann, H. et al. 1995  Arch. Virol.  140:21.3-221). The E glycoprotein is responsible for cell attachment, possibly mediated by a receptor, and for fusion with the cell membranes following viral entry. 
     Dengue infection produces fever, rash, and joint pain in humans. A more severe and life-threatening form of dengue is characterized by hemorrhagic fever and hemorrhagic shock (severe dengue (SD)). Passive immunization with clinically acceptable dengue virus neutralizing antibodies is an option for prevention and treatment of Dengue virus infection. In particular, highly efficient neutralizing antibodies may be useful for consideration as a possible therapy for severe dengue virus infection. Neutralizing antibodies specific for the E glycoprotein have been shown to be capable of protecting against dengue virus infection. Some such neutralizing antibodies specifically bind to F dimer or trimer epitopes that bridge two or three envelope protein subunits that make up the 90 repeating dimers on the mature virion. Monoclonal antibodies reactive to flavivirus envelope proteins have been shown to mediate protection against homologous virus challenge in animal models (Mathews, J. H. and Roehrig, J. T. 11984)  J. Immunol.  132:1533-1537; Brandriss, M. W. et al. (1986)  J. Gen. Virol.  67:229-234, Gould, E. A. et. al. (1986)  J. Gen. Virol.  67:591-595; Kaufman, B. M. et al. (1987)  Am. Trop. Med. Hyg.  36:427-434; Kimura-Kuroda, S., and Yasui, K. (1988)  J. Virol.  141:3606-3510). In most cases, protection by passive immunization has been correlated with the ability of these antibodies to neutralize the virus in vitro. Protection against dengue virus challenge was also demonstrated in mice following passive immunization with monoclonal or polyclonal antibodies specific to prM (Bray, M., and C. J. Lai. 1991  Virology  185:505-508; Kaufman, B M et al. 1987  Am. J. Trop. Med. Hyg.  36:427-434) or NS1 (Falgout, B. et al. 1990.  J. Virol.  64:4356-4363 Henchal, E. A. et al. 1988  J. Gen. Virol.  69:2101-2107). 
     Biomarkers for early detection of SD based on molecular features of the patients blood have been proposed. These efforts have focused on two experimental techniques: (i) flow cytometry of fixed blood cell populations (Durbin A. P., et al, (2008)  Virology  376:429-435), and (ii) gene expression in bulk RNA extracted from blood or peripheral mononuclear blood cells (PBMCs) (Ubol S, et al. (2008)  J Infect Dis.  197:1459-11167; Fink J, et al. (2007)  PLoS Negl Trop Dis.  1:e86; Sessions O. M., et al. (2013)  PLoS Negl Trop Dis.  7:e2107; Nikolayeva T, et al. (2018)  J Infect Dis.  217:1690-1698). Although useful, these studies suffer from several limitations. The majority of these studies identified genes whose altered expression is associated with but does not precede the onset of SD and therefore cannot be used as prognostic biomarkers. From a technical standpoint, flow cytometry has a high throughput but is constrained to a few protein markers that are selected a priori, making it excellent for separating known, discrete cell populations but less appropriate for screening the complex, dynamic landscape of cell types, subtypes, and states characteristic of immune responses. Transcriptomics performed on bulk cell populations can screen thousands of genes but its resolution is limited, because it cannot capture tissue heterogeneity. Averaging the signal over various cell populations is confounded by changes both in abundances of cell types and activation states. Coupling fluorescence activated cell sorting (FACS) with single cell transcriptomics can potentially combine the advantages of both approaches (Darmanis S, et al. (2017)  Cell Reports  21: 1399-1410). It has also been challenging to identify DENV-associated and DENV-infected immune cells in humans. 
     B. Antibodies 
     The present disclosure provides compositions and methods for treating and diagnosing a Dengue virus infection (Dengue fever). Antibodies or antigen binding portions thereof that specifically or selectively bind Dengue virus antigens are provided. As used herein, the terms specifically binds to, specific for, selectively binds and selective for a Dengue virus antigen or an epitope on a Dengue virus protein mean binding that is measurably different from a non-specific or non-selective interaction. Specific binding can be measured, for example, by determining binding of a molecule compared to binding of a control molecule. Specific binding can also be determined by competition with a control molecule that is similar to the target, such as an excess of non-labeled target. In that case, specific binding is indicated if the binding of the labeled target to a probe is competitively inhibited by the excess non-labeled target. 
     An antibody, as used herein, can refer to an intact antibody (e.g., an intact immunoglobulin) and antibody fragment, for example, an antigen binding fragment. Antigen binding fragments comprise at least one antigen binding domain. One example of an antigen binding domain is an antigen binding domain formed by a V H -V L  dimer. Antibodies and antigen binding fragments can be described by the antigen to which they specifically bind. 
     The V H  and V L  regions can be further subdivided into regions of hypervariability (hypervariable regions (HVRs), also called complementarity determining regions (CDRs)) interspersed with regions that are more conserved. The more conserved regions are called framework regions (FRs). Each V H  and V L  generally comprises three CDRs and four FRs, arranged in the following order (from N-terminus to C-terminus): FR1-CDR1-FR2-CDR2-FR3-CDR3-FR4. The CDRs are involved in antigen binding, and confer antigen specificity, and binding affinity to the antibody. (See Kabat et al, (1991)  Sequences of Proteins of Immunological Interest  5th ed., Public Health Service, National Institutes of Health, Bethesda, Md.) CDR sequences on the heavy chain (V H ) may be designated as CDRH1, 2, 3, while CDR sequences on the light chain (V v ) may be designated as CDRL1, 2, 3.

The twenty natural or genetically encoded alpha-amino acids are as follows: alanine (Ala or A), arginine (Arg or R), asparagine (Asn or N), aspartic acid (Asp or D), cysteine (Cys or C), glutamine (Gln or Q), glutamic acid (Glu or E), glycine (Gly or G), histidine (His or H), isoleucine (Ile or I), leucine (Leu or L), lysine (Lys or K), methionine (Met or M), phenylalanine (Phe or F), proline (Pro or P), serine (Ser or S), threonine (Thr or T), tryptophan (Trp or W), tyrosine (Tyr or Y), and valine (Val or V). The structures of these twenty natural amino acids are shown in, e.g., Stryer et al., Biochemistry, 5 th  ed., Freeman and Company (2002). The term amino acid also includes unnatural amino acids, modified amino acids (e.g., having modified side chains and/or backbones), and amino acid analogs. 
     The terms identical or percent identity, in the context of two or more nucleic acids or polypeptide sequences, refer to two or more sequences or subsequences that are the same or have a specified percentage of nucleotides or amino acid residues that are the same (e.g., 90%, or 95?/or greater identity over a specified region), when compared and aligned for maximum correspondence over a comparison window, or designated region as measured using one of the following sequence comparison algorithms or by manual alignment and visual inspection. 
     Identity or similarity with respect to a sequence is defined as the percentage of amino acid residues in the candidate sequence that are identical (i.e., same residue) with the starting amino acid residues, after aligning the sequences and introducing gaps, if necessary, to achieve the maximum percent sequence identity. Methods of alignment of sequences for comparison are well known in the art. Optimal alignment of sequences for comparison can be conducted, for example, by the local homology algorithm of Smith and Waterman ( Adv. Appl. Math.  2:482, 1970), by the homology alignment algorithm of Needleman and Wunsch ( J. Mol. Biol.  48:443, 1970), by the search for similarity method of Pearson and Lipman ( Proc. Natl. Acad. Sci. USA  85:2444, 1988), by computerized implementations of these algorithms (e.g, GAP, BESTFIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group, 575 Science Dr., Madison, Wis.), or by manual alignment and visual inspection (see, e.g., Ausubel et al.,  Current Protocols in Molecular Biology  (1995 supplement)). 
     As with all peptides, polypeptides, and proteins, including fragments thereof, it is understood that additional modifications in the amino acid sequence of the Dengue virus antigen-specific antibodies or antigen binding fragments thereof described herein, for example, in the heavy chain variable region and/or light chain variable region, can occur that do not alter the nature or function of the antibodies or antigen binding fragments thereof. Such modifications include conservative amino acids substitutions, such that each recited sequence optionally contains one or more conservative amino acid substitutions. The list provided below identifies groups that contain amino acids that are conservative substitutions for one another; these groups are exemplary as other conservative substitutions are known to those of skill in the art. 
     1) Alanine (A), Glycine (G); 
     2) Aspartic acid (D), Glutamic acid (E); 
     3) Asparagine (N), Glutamine (Q); 
     4) Arginine (R), Lysine (K); 
     5) Isoleucine (I), Leucine (L), Methionine (M), Valine (V); 
     6) Phenylalanine (F), Tyrosine (Y), Tryptophan (W); 
     7) Serine (S), Threonine (T); and 
     8) Cysteine (C), Methionine (M) 
     By way of example, when an aspartic acid at a specific residue is mentioned, also contemplated is a conservative substitution at the residue, for example, glutamic acid, Non-conservative substitutions, for example, substituting a proline with glycine, are also contemplated. 
     In some instances, the affinity of Dengue virus antigen-specific antibodies or antigen binding fragments thereof may be optimized through mutations to increase or decrease affinity as desired based on one or more of the known characteristics of the binding interaction with the cognant Dengue virus antigen, the structure of either or both of the antibodies or fragments thereof, or the Dengue virus antigen. In some instances, the mutations permits facile elution of purified antibodies or fragments thereof under desirable elution conditions during isolation and purification. 
     Methods of generating and screening for antibodies and antigen binding fragments thereof as provided in this disclosure are described in the Examples and are well-known in the art. Methods of further modifying antibodies for enhanced properties (e.g., enhanced affinity, chimerization, humanization) as well as generating antigen binding fragments, as described herein, are also well-known in the art. 
     The present disclosure also encompasses antibodies or fragments thereof that bind to the same epitope of Dengue virus antigens as the antibodies disclosed herein. Such antibodies can be identified using routine techniques known in the art, including, for example, competitive binding assays. 
     The term epitope, as used herein, means a component of an antigen capable of specific binding to an antibody or antigen binding fragment thereof. Such components optionally comprise one or more contiguous amino acid residues and/or one or more non-contiguous amino acid residues. Epitopes frequently consist of surface-accessible amino acid residues and/or sugar side chains and can have specific three-dimensional structural characteristics, as well as specific charge characteristics. Conformational and non-conformational epitopes are distinguished in that the binding to the former but not the latter is lost in the presence of denaturing solvents. An epitope can comprise amino acid residues that are directly involved in the binding, and other amino acid residues, which are not directly involved in the binding. The epitope to which an antigen binding protein binds can be determined using known techniques for epitope determination such as, for example, testing for antigen binding protein binding to antigen variants with different point mutations. 
     The present disclosure also provides chimeric antibodies. The term chimeric antibody refers to an antibody in which a component of the heavy and/or light chain is derived from a particular source or species, while the remainder of the heavy and/or light chain is derived from a different source or species. 
     A human antibody is one that possesses an amino acid sequence corresponding to that of an antibody produced by a human or a human cell, or derived from a non-human source that utilizes a human antibody repertoire or human antibody-encoding sequences (e.g., obtained from human sources, genetically modified non-human sources or designed de novo), Human antibodies specifically exclude humanized antibodies. 
     Humanized forms of non-human antibodies are chimeric antibodies that contain minimal sequence derived from the non-human antibody. A humanized antibody is generally a human immunoglobulin (recipient antibody) in which residues from one or more CDRs are replaced by residues from one or more CDRs of a non-human antibody (donor antibody). The donor antibody can be any suitable non-human antibody, such as a mouse, rat, rabbit, chicken, or non-human primate antibody having a desired specificity, affinity, or biological effect. In some instances, selected framework region residues of the recipient antibody are replaced by the corresponding framework region residues from the donor antibody. Humanized antibodies can also comprise residues that are not found in either the recipient antibody or the donor antibody. Such modifications can be made to further refine antibody function. (See Jones et al. (1986)  Nature,  321:522-525; Riechmann et al. (1988)  Nature,  332:323-329; and Presta, (1992)  Curr Op Struct Biol.,  2:593-596). 
     In some embodiments, the antibody or antigen binding fragment thereof provided herein can include a heavy (H) chain variable domain sequence (abbreviated herein as VH), and a light (L) chain variable domain sequence (abbreviated herein as VL). In some embodiments, an antibody molecule comprises or consists of a heavy chain and a light chain (referred to as a half antibody). In another example, an antibody molecule includes two heavy (H) chain variable domain sequences and two light (L) chain variable domain sequence, thereby forming two antigen binding sites, such as Fab, Fab′, F(ab) 2 , Fc, Fd, Fd′, Fv, single chain antibodies (scFv, for example), single variable domain antibodies, diabodies (Dab) (bivalent and bispecific), and chimeric (e.g., humanized) antibodies, which may be produced by the modification of whole antibodies or synthesized de novo using recombinant DNA technologies. These functional antibody fragments retain the ability to selectively bind with their respective antigen. Antibodies and antibody fragments can be from any class of antibodies including, but not limited to, IgG, IgA IgM, IgD, and IgE, and from any subclass (e.g., IgG1, IgG2, IgG3, and IgG4) of antibodies. The preparation of antibody molecules can be monoclonal or polyclonal. An antibody molecule can also be a human, humanized, CDR-grafted, or an in vitro generated antibody. The antibody can have a heavy chain constant region chosen from, e.g., IgG1, IgG2, IgG3, or IgG4. The antibody can also have a light chain chosen from either kappa or lambda light chains. 
     As used herein, the term monoclonal antibody refers to an antibody from a population of substantially homogeneous antibodies. A population of substantially homogeneous antibodies comprises antibodies that are the same or substantially similar and that bind the same epitope(s), except for variants that can normally arise during production of the monoclonal antibody. Such variants are generally present in only minor amounts. A monoclonal antibody is typically obtained by a process that includes the selection of a single antibody from a plurality of antibodies. For example, the selection process can be the selection of a unique clone from a plurality of clones, such as a pool of yeast clones, phage clones, bacterial clones, mammalian cell clones, hybridoma clones, or other recombinant DNA clones. The selected antibody can be further altered, for example, to improve affinity for the target, for example, by affinity maturation, to humanize the antibody, to improve its production in cell culture, and/or to reduce its immunogenicity in a subject. 
     Antigen binding fragments of an antibody molecule are well known in the art, and include, for example, (i) a Fab fragment, a monovalent fragment consisting of the VL, VH, CL and CH1 domains; (ii) a F(ab′)2 fragment, a bivalent fragment comprising two Fab fragments linked by a disulfide bridge at the hinge region; (iii) a Fd fragment consisting of the VH and CH1 domains; (iv) a Fv fragment consisting of the VL and VH domains of a single arm of an antibody, (v) a diabody (dAb) fragment, which consists of a VH domain; (vi) a camelid or camelized variable domain; (vii) a single chain Fv (scFv) (see e.g., Bird et al. (1988)  Science  242:423-426; Huston et al. (1988)  Proc. Natl. Acad. Sci. USA  85:5879-5883); (viii) a single domain antibody. These antibody fragments are obtained using conventional techniques known to those skilled in the art, and the fragments are screened for utility in the same manner as are intact antibodies. 
     In certain embodiments, antibodies and antibody compositions as provided herein are distinguishable from naturally occurring antibodies and compositions in one or more respects. Such distinguishable antibodies and compositions may be referred to as “synthetic,” or may be identified by the proviso that the antibody or composition “is not naturally occurring” or affirmatively as “non-naturally occurring,” As used herein the terms “corresponding antibody,” and “corresponding to” describes the relationship between (1) an antibody characterized by six specific CDR sequences and produced by immune cells of a study subject described in the Examples below and (2) a synthetic antibody comprising the same six CDR sequences. Synthetic antibodies of this disclosure may differ in structure from naturally occurring antibodies with the same CDRs. That is, synthetic antibodies identified by specified CDRs may be structurally different from antibodies comprising the specified CDRs that are produced by cells of the study subject described in the Examples below. Possible differences for synthetic antibodies include variable region sequences that differ corresponding naturally occurring antibodies, different light chain sequences (i.e. lambda type instead of kappa type or vice versa), different isotypes, different allotypes, and different constant domain variants. These differences are discussed in more detail below. 
     In one approach, an antibody heavy chain comprises the CDRs of a clone described herein with the proviso that the antibody heavy chain does not comprise the heavy chain variable region sequence associated with the clone described herein. For illustration, in one embodiment an antibody that comprises the CDRs of Clone J9 does not have a heavy chain variable region that comprises SEQ ID NO:12. In another approach, an antibody light chain comprises the CDRs of a clone described herein with the proviso that the antibody light chain does not comprise the light chain variable region sequence associated with the clone described herein. For illustration, in one embodiment an antibody that comprises the CDRs of Clone J9 does not have a light chain variable region that comprises SEQ ID NO:88. In one approach both the heavy chain and the light chain variable region of an antibody of the invention have an amino acid sequence other than the sequence disclosed herein. 
     In some embodiments the synthetic antibody with specified CDRs is an isotype other the isotype(s) found associated with the study subject from which B cells with the specified CDRs was derived. In some embodiments the antibody disclosed herein is an isotype other than IgG1. In some embodiments the antibody disclosed herein is an isotype other than IgG2. In some embodiments the antibody disclosed herein is an isotype other than IgG3. In some embodiments the antibody disclosed herein is an isotype other than IgG4. In some embodiments the antibody disclosed herein is an isotype other than IgM. In some embodiments the antibody disclosed herein is an isotype other than IgA. In some embodiments the synthetic antibody comprises lambda type light chains. In some embodiments the synthetic antibody comprises kappa type light chains. 
     In some embodiments, the monoclonal antibody comprises a heavy chain variable region sequence and a light chain variable region sequence that are derived from an immunoglobulin producing human B cell, and further comprises a kappa or lambda light chain constant region. In some embodiments, the light chain constant region (kappa or lambda) is from the same type of light chain (i.e., kappa or lambda) as the light chain variable region that was derived from the immunoglobulin producing human B cell; as a non-limiting example, if an IgE-producing human B cell comprises a kappa light chain, then the monoclonal antibody that is produced can comprise the light chain variable region from the IgE-producing B cell and further comprises a kappa light chain constant region. 
     In some embodiments, the monoclonal antibody comprises a heavy chain variable region sequence and a light chain variable region sequence that are derived from an immunoglobulin-producing human B cell, and further comprises a heavy chain constant region having an IgG isotype IgG4), an IgA isotype (e.g., IgA1), an IgM isotype, an IgD isotype, or that is derived from an IgG, IgA, IgM, or IgD isotype (e.g., is a modified IgG4 constant region). It will be appreciated by a person of ordinary skill in the art that the different heavy chain isotypes (IgA, IgD, IgE, IgG, and IgM) have different effector functions that are mediated by the heavy chain constant region, and that for certain uses it may be desirable to have an antibody that has the effector function of a particular isotype IgG). 
     In some embodiments, the monoclonal antibody comprises a native (i.e., wild-type) human IgG, IgA, IgM, or IgD constant region. In some embodiments, the monoclonal antibody comprises a native human IgG1 constant region, a native human IgG2 constant region, a native human IgG3 constant region, a native human IgG4 constant region, a native human IgA1 constant region, a native human IgA2 constant region, a native human IgM constant region, or a native human IgD constant region. In some embodiments, the monoclonal antibody comprises a heavy chain constant region that comprises one or more modifications. It will be appreciated by a person of ordinary skill in the art that modifications such as amino acid substitutions can be made at one or more residues within the heavy chain constant region that modulate effector function. In some embodiments, the modification reduces effector function, e.g., results in a reduced ability to induce certain biological functions upon binding to an Fc receptor expressed on an effector cell that mediates the effector function. In some embodiments, the modification (e.g, amino acid substitution) prevents in vivo Fab arm exchange, which can introduce undesirable effects and reduce the therapeutic efficacy of the antibody. See, e.g., Silva et al.,  J Biol Chem,  2015, 280:5462-5469 
     In some embodiments, the monoclonal antibody comprises a native (i.e., wild-type) human IgM constant region, human IgD constant region, human IgG constant region that is derived from IgG1, IgG2, IgG3, or IgG4, or human IgA constant region that is derived from IgA1 or IgA2 and comprises one or more modifications that modulate effector function. Ini some embodiments the monoclonal antibody comprises a human IgM constant region, human IgD constant region, human IgG constant region that is derived from IgG1, IgG2, IgG3, or IgG4, or human IgA constant region that is derived from IgA1 or IgA2. In some embodiments, the monoclonal antibody comprises a native i.e., wild-type) human IgM constant region, human IgD constant region, human IgG constant region that is derived from IgG1, IgG2, IgG3, or IgG4, or human IgA constant region that is derived from IgA1 or IgA2 and comprises one, two, three, four, five, six, seven, eight, nine, ten or more modifications (e.g., amino acid substitutions). In some embodiments the constant regions includes variations (e.g., one, two, three, four, five, six, seven, eight, nine, ten or more amino acid substitutions) that reduce effector function. 
     In some embodiments the synthetic antibody with specified CDRs is an allotype other the allotype(s) found associated with the study subject from which B cells with the specified CDRs was derived. In some embodiments, the synthetic antibody of the invention comprises an allotype selected from those listed in Table 5, below, which is different from an allotype of antibodies from the corresponding study subject. In some embodiments the synthetic antibody of the invention comprises any individual allotype selected from those listed in Table 5, with the proviso that the allotype differs from the corresponding allotype of antibodies from a study subject.

                 NB: Alphabetical notation given within brackets.

     In some embodiments, a monoclonal antibody comprises CDR sequences, a heavy chain variable region, and/or a light chain variable region from an antibody from a B cell as described herein (e.g., as disclosed in Tables 1-2) and further comprises a heavy chain constant region and/or a light chain constant region that is heterologous to the antibody from the B cell from which the CDR sequences and/or variable region sequences are derived. For example, in some embodiments, the monoclonal antibody comprises the CDR sequences and/or variable region sequences of an antibody from a B cell, and further comprises a heavy chain constant region and a light chain constant region that is heterologous to the antibody from the B cell (e.g., the heavy chain constant region and/or light chain constant region is a wild-type or modified IgG1, IgG2, IgG3, or IgG4 constant region, or the heavy chain constant region and/or light chain constant region comprises one or more modifications (e.g., amino acid substitutions) relative to the native constant region of the antibody from the IgE B cell. 
     Synthetic antibodies of this disclosure may comprise variations in heavy chain constant regions to change the properties of the synthetic antibody relative to the corresponding naturally occurring antibody. Exemplary changes include mutations to modulate antibody effector function (e.g., complement-based effector function or FcγR-based effector function), alter half-like, modulate coengagement of antigen and FcγRs, introduce or remove glycosylation motifs (glyco-engineering). See Fonseca et al., 2018, “Boosting half-life and effector functions of therapeutic antibodies by Fc-engineering: An interaction-function review”  Int J Biol Macromol.  19:306-311; Wang et al., 2018; “IgG Fc engineering to modulate antibody effector functions”  Protein Cell  2018, 9(1):63-73, Schlothauer, 2016, “Novel human IgG1 and IgG4 Fe-engineered antibodies with completely abolished immune effector functions,”  Protein Engineering, Design and Selection  29(10):457-466; Tam et al., 2017, “Functional, Biophysical, and Structural Characterization of Human IgG1 and IgG4 Fc Variants with Ablated Immune Functionality”  Antibodies  6, 12, each incorporated herein by reference for all purposes. 
     In some embodiments, the heavy chain variable region and/or the light chain variable region of the monoclonal antibody has an identical sequence to the heavy chain variable region and/or the light chain variable region encoded by the immunoglobulin producing single B cell from the human subject having Dengue. In some embodiments, the heavy chain variable region and/or the light chain variable region of the monoclonal antibody comprises one or more modifications, e.g., amino acid substitutions, deletions, or insertions. 
     The heavy chain variable region sequence and/or light chain variable region sequence of an antibody described herein can be engineered to comprise one or more variations in the heavy chain variable region sequence and/or light chain variable region sequence. In some embodiments, the engineered variation(s) improves the binding affinity of the antibody for a Dengue virus (e.g., DEN-1, DEN-2, DEN-3, DEN-4). In some embodiments, the engineered variation(s) improves the cross-reactivity of the antibody for a second Dengue virus. 
     In some embodiments, the engineered variation is a variation in one or more CDRs, e.g., an amino acid substitution in a heavy chain CDR and/or a light chain CDR as described herein. In some embodiments, the engineered variation is a variation in one or more framework regions, e.g., an amino acid substitution in a heavy chain framework region and/or a light chain framework region. In some embodiments, the engineered variation is a reversion of a region of the heavy chain and/or light chain sequence to the inferred naïve sequence. Methods for determining an inferred naive immunoglobulin sequence are described in the art. See, e.g., Magnani et al.,  PLoS Negl Trop Dis,  2017, 11:e0005655, doi:10.1371/journal.pntd.0005655 
     In some embodiments, affinity maturation is used to engineer further mutations that enhance the binding affinity of the antibody for a Dengue virus or enhance the cross-reactivity of the antibody for a second Dengue virus. Methods for performing affinity maturation are known in the art. See, e.g., Renaut et al.,  Methods Mol Biol,  2012, 907:451-461. 
     Antibody molecules can also be single domain antibodies. Single domain antibodies can include antibodies whose complementary determining regions are part of a single domain polypeptide. Examples include, but are not limited to, heavy chain antibodies, antibodies naturally devoid of light chains, single domain antibodies derived from conventional 4-chain antibodies, engineered antibodies and single domain scaffolds other than those derived from antibodies. Single domain antibodies may be any of the art, or any future single domain antibodies. Single domain antibodies may be derived from any species including, but not limited to mouse, rat, guinea, pig, human, camel, llama, fish, shark, goat, rabbit, and bovine. Single domain antibodies are described, for example, in International Application Publication No. WO 94/04678. For clarity reasons, this variable domain derived from a heavy chain antibody naturally devoid of light chain is known herein as a VHH or nanobody to distinguish it from the conventional VH of four chain immunoglobulins. Such a VHH molecule can be derived from antibodies raised in Camelidae species (e.g., camel, llama, dromedary, alpaca and guanaco) or other species besides Camelidae. 
     In some embodiments, an antigen binding fragment can also be or can also comprise, e.g., a non-antibody, scaffold protein. These proteins are generally obtained through combinatorial chemistry-based adaptation of preexisting antigen-binding proteins. For example, the binding site of human transferrin for human transferrin receptor can be diversified using the system described herein to create a diverse library of transferrin variants, some of which have acquired affinity for different antigens. See, e.g., Ali et al. (1999)  J. Biol. Chem.  274:24066-24073. The portion of human transferrin not involved with binding the receptor remains unchanged and serves as a scaffold, like framework regions of antibodies, to present the variant binding sites. The libraries are then screened, as an antibody library is screened, and in accordance with the methods described herein, against a target antigen of interest to identify those variants having optimal selectivity and affinity for the target antigen. See, e.g., Hey et al. (2005)  TRENDS Biotechnol  23(10):514-522. 
     One of skill in the art would appreciate that the scaffold portion of the non-antibody scaffold protein can include, e.g., all or part of the Z domain of  S. aureus  protein A, human transferrin, human tenth fibronectin type 111 domain, kunitz domain of a human trypsin inhibitor, human CTLA-4, an ankyrin repeat protein, a human lipocalin (e.g., anticalins, such as those described in, e.g., International Application Publication No. WO2015/104406), human crystallin, human ubiquitin, or a trypsin inhibitor from  E. elaterium.    
     Synthetic antibody compositions of this disclosure may differ from naturally occurring compositions in at least one or more of the following respects: (i) composition comprises antibodies that are purified, i.e., separated from tissue or cellular material with which they are associated in the human body, and optionally in an manufactured excipient or medium; and/or (ii) antibody compositions of the invention contain a single species of antibody (are monoclonal) such that all antibodies in the composition have the same structure and specificity. 
     C. Expression and Purification of Antibodies 
     The Dengue virus antigen-specific antibodies or antigen binding fragments thereof disclosed herein may be produced by recombinant expression in a human or non-human cell. Synthetic antibody-producing cells include non-human cells expressing heavy chains, light chains, or both heavy and light chains; human cells that are not immune cells heavy chains, light chains, or both heavy and light chains; and human B cells that produce heavy chains or light chains, but not both heavy and light chains. Synthetic antibodies of this disclosure may be are heterologously expressed, in vitro or in vivo, in cells other than human B cells, such as non-human cells and human cells other than B cells, optionally other than immune cells, and optionally in cells other than cells in a B cell lineage. 
     The Dengue virus antigen-specific antibodies or antigen binding fragments thereof disclosed herein can be produced using a variety of techniques known in the art of molecular biology and protein chemistry. For example, a nucleic acid encoding the antibody or antigen binding fragment thereof can be inserted into an expression vector that contains transcriptional and translational regulatory sequences, which include, e.g., promoter sequences, ribosomal binding sites, transcriptional start and stop sequences, translational start and stop sequences, transcription terminator signals, polyadenylation signals, and enhancer or activator sequences. The regulatory sequences include a promoter and transcriptional start and stop sequences. In addition, the expression vector can include more than one replication system, such that it can be maintained in two different organisms; for example, in mammalian or insect cells for expression and in a prokaryotic host for cloning and amplification. 
     Several possible vector systems are available for the expression of cloned heavy chain and light chain polypeptides from nucleic acids in mammalian cells. One class of vectors relies upon the integration of the desired gene sequences into the host cell genome. Cells that have stably integrated DNA can be selected by simultaneously introducing drug resistance genes such as  E. coli  gpt (Mulligan and Berg (1981)  Proc Natl Acad Sci USA  78:2072) or Tn5 neo (Southern and Berg (1982)  Mol Appl Genet  1:327). The selectable marker gene can be either linked to the DNA gene sequences to be expressed or introduced into the same cell by co-transfection (Wigler et al. (1979)  Cell  16:77). A second class of vectors utilizes DNA elements that confer autonomously replicating capabilities to an extrachromosomal plasmid. These vectors can be derived from animal viruses, such as bovine papillomavirus (Sarver et al. (1982)  Proc Natl Acad Sci USA,  79:7147), CMV, polyoma virus (Deans et al. (1984)  Proc Natl Acad Sci USA  81:1 or SV40 virus (Lusky and Botchan (1981)  Nature  293:79). 
     The expression vectors can be introduced into cells in a manner suitable for subsequent expression of the nucleic acid. The method of introduction is largely dictated by the targeted cell type, discussed below. Exemplary methods include CaPO 4  precipitation, liposome fusion, cationic liposomes, electroporation, nucleoporation, viral infection, dextran-mediated transfection, polybrene-mediated transfection, protoplast fusion, and direct microinjection. 
     Appropriate host cells for the expression of antibodies or antigen binding fragments thereof include yeast, bacteria, insect, plant, and mammalian cells. Of particular interest are bacteria such as  E. coli , fungi such as  Saccharomyces cerevisiae  and  Pichia pastoris , insect cells such as SF9, mammalian cell lines (e.g., human cell lines), as well as primary cell lines. 
     In some embodiments, an antibody or fragment thereof can be expressed in, and purified from, transgenic animals (e.g., transgenic mammals). For example, an antibody can be produced in transgenic non-human mammals (e.g., rodents) and isolated from milk as described in, e.g., Houdebine (2002)  Curr Opin Biotechnol  13(6):625-629; van Kuik-Romeijn et al. (2000)  Transgenic Res  9(2):155-159; and Pollock et al, (1999)  J Immunol Methods  231(1-2):147-157. 
     The antibodies and fragments thereof can be produced from the cells by culturing a host cell transformed with the expression vector containing nucleic acid encoding the antibodies or fragments, under conditions, and for an amount of time, sufficient to allow expression of the proteins. Such conditions for protein expression vary with the choice of the expression vector and the host cell and are easily ascertained by one skilled in the art through routine experimentation. For example, antibodies expressed in  E. coli  can be refolded from inclusion bodies (see, e.g., Hou et al. (1998)  Cytokine  10:319-30). Bacterial expression systems and methods for their use are known in the art (see Ausubel et al. (1988)  Current Protocols in Molecular Biology , Wiley &amp; Sons; and Green and Sambrook (012)  Molecular Cloning—A Laboratory Manual,  4th Ed., Cold Spring Harbor Laboratory Press, New York (2001)). The choice of codons, suitable expression vectors and suitable host cells vary depending on a number of factors, and may be easily optimized as needed. An antibody (or fragment thereof) described herein can be expressed in mammalian cells or in other expression systems including but not limited to yeast, baculovirus, and in vitro expression systems (see, e.g., Kaszubska et al. (2000)  Protein Expression and Purification  18:213-220). 
     In vitro methods are also suitable for preparing monovalent antibodies. or fragments. Digestion of antibodies to produce fragments thereof, particularly, Fab fragments, can be accomplished using routine techniques known in the art. For instance, digestion can be performed using papain. Examples of papain digestion are described in International Application Publication No. WO 94/29348, U.S. Pat. No. 4,342,566, and Harlow and Lane, Antibodies, A Laboratory Manual, Cold Spring Harbor Publications, New York, (1988). Papain digestion of antibodies typically produces two identical antigen binding fragments, called Fab fragments, each with a single antigen binding site, and a residual Fe fragment. Pepsin treatment yields a fragment, called the F(ab′)2 fragment that has two antigen combining sites and is still capable of cross-linking antigen. 
     The Fab fragments produced in antibody digestion can also contain the constant domains of the light chain and the first constant domain of the heavy chain. Fab′ fragments differ from Fab fragments by the addition of a few residues at the carboxy terminus of the heavy chain domain including one or more cysteines from the antibody hinge region. The F(ab′)2 fragment is a bivalent fragment comprising two Fab′ fragments linked by a disulfide bridge at the hinge region. Fab′-SH is the designation herein for Fab′ in which the cysteine residue(s) of the constant domains bear a free thiol group. 
     One method of producing proteins comprising the provided antibodies or fragments is to link two or more peptides or polypeptides together by protein chemistry techniques. For example, peptides or polypeptides can be chemically synthesized using currently available laboratory equipment using either Fmoc (9-fluorenylmethyl-oxycarbonyl) or Boc (tert-butyloxycarbonoyl) chemistry (Applied. Biosystems, Inc.; Foster City, Calif.). Those of skill in the art readily appreciate that a peptide or polypeptide corresponding to the antibody provided herein, for example, can be synthesized by standard chemical reactions. For example, a peptide or polypeptide can be synthesized and not cleaved from its synthesis resin whereas the other fragment of an antibody can be synthesized and subsequently cleaved from the resin, thereby exposing a terminal group that is functionally blocked on the other fragment. By peptide condensation reactions, these two fragments can be covalently joined via a peptide bond at their carboxyl and amino termini, respectively, to form an antibody, or fragment thereof. (Grant G A (1992) Synthetic Peptides: A User Guide. W.H. Freeman and Co., N.Y. (1992); Bodansky M and Trost B., Ed. (1993) Principles of Peptide Synthesis. Springer Verlag Inc., NY). Alternatively, the peptide or polypeptide can by independently synthesized in vivo. Once isolated, these independent peptides or polypeptides may be linked to form an antibody or fragment thereof via similar peptide condensation reactions. 
     For example, enzymatic ligation of cloned or synthetic peptide segments can allow relatively short peptide fragments to be joined to produce larger peptide fragments, polypeptides or whole protein domains (Abrahmsen et al.,  Biochemistry,  30:4151 (1991)). Alternatively, native chemical ligation of synthetic peptides can be utilized to synthetically construct large peptides or polypeptides from shorter peptide fragments. This method consists of a two step chemical reaction (Dawson et al.,  Science,  266:776 779 (1994)). The first step is the chemoselective reaction of an unprotected synthetic peptide a thioester with another unprotected peptide segment containing an amino terminal Cys residue to give a thioester linked intermediate as the initial covalent product. Without a change in the reaction conditions, this intermediate undergoes spontaneous, rapid intramolecular reaction to form a native peptide bond at the ligation site. Application of this native chemical ligation method to the total synthesis of a protein molecule is illustrated by the preparation of human interleukin 8 (IL-8) (Baggiolini et al.,  FEBS Lett.  307:97-101 (1992); Clark et al.,  J. Biol. Chem.  269:16075 (1994); Clark et al.,  Biochemistry  30:3128 (1991); Rajarathnam et al.,  Biochemistry  33:6623-30 (1994)). 
     Alternatively, unprotected peptide segments can be chemically linked where the bond formed between the peptide segments as a result of the chemical ligation is an unnatural (non-peptide) bond (Schnolzer et al.,  Science  256:221 (1992)). This technique has been used to synthesize analogs of protein domains as well as large amounts of relatively pure proteins with full biological activity (deLisle et al., Techniques in Protein Chemistry IV. Academic Press, New York, pp. 257-267 (1992)). 
     Recombinant techniques can also be used to modify antibodies or antigen binding fragments thereof. For example, amino acids found to not contribute to either the activity or the binding specificity or affinity of the antibody can be deleted without a loss in the respective activity. Insertions, deletions, substitutions, or other selected modifications of particular regions or specific amino acids residues, provided the activity of the fragment is not significantly altered or impaired compared to the non-modified antibody, or antigen binding fragment thereof can be made. Such methods are readily apparent to a skilled practitioner in the art and can include site specific mutagenesis of the nucleic acid encoding the antibody or fragment thereof. (Zoller et al.,  Nucl. Acids Res.  10:6487-500 (1982)). 
     Following expression, the antibodies and fragments thereof can be isolated. An antibody or fragment thereof can be isolated or purified in a variety of ways known in the art depending on what other components are present in the sample. Standard purification methods include electrophoretic, molecular, immunological, and chromatographic techniques, including ion exchange, hydrophobic, affinity, and reverse-phase HPLC chromatography. For example, an antibody can be purified using a standard anti-antibody column (e.g., a protein-A or protein-G-column). Ultrafiltration and diafiltration techniques, in conjunction with protein concentration, are also useful. See, e.g., Scopes (1994)  Protein Purification,  3 rd  edition, Springer-Verlag, New York City, N.Y. The degree of purification necessary varies depending on the desired use. In some instances, no purification of the expressed antibody or fragments thereof is necessary. 
     Methods for determining the yield or purity of a purified antibody or fragment thereof are known in the art and include, e.g., Bradford assay, UV spectroscopy, Biuret protein assay, Lowry protein assay, amino black protein assay, high pressure liquid chromatography (HPLC), mass spectrometry (MS), and gel electrophoretic methods (e.g., using a protein stain such as Coomassie Blue or colloidal silver stain). 
     D. Modification of Antibodies 
     Any of the Dengue virus antigen-specific antibodies or antigen binding fragments thereof described herein can be modified. The modifications can be covalent or non-covalent modifications. Such modifications can be introduced into the antibodies or antigen binding fragments by, e.g., reacting targeted amino acid residues of the polypeptide with an organic derivatizing agent that is capable of reacting with selected side chains or terminal residues. Suitable sites for modification can be chosen using any of a variety of criteria including, e.g., structural analysis or amino acid sequence analysis of the antibodies or fragments. In some instances, the Dengue virus antigen-specific antibodies or antigen binding fragments may be labeled by a variety of means for use in diagnostic and/or pharmaceutical applications. 
     In some embodiments, the antibodies or antigen binding fragments thereof can be conjugated to a heterologous moiety. The heterologous moiety can be, e.g., a heterologous polypeptide, a therapeutic agent (e.g., a toxin or a drug), or a detectable label such as, but not limited to, a radioactive label, an enzymatic label, a fluorescent label, a heavy metal label, a luminescent label, or an affinity tag such as biotin or streptavidin. Suitable heterologous polypeptides include, e.g., an antigenic tag (e.g., FLAG (DYKDDDDK) (SEQ ID NO:339), polyhistidine (6-His; HHHHHH (SEQ ID NO:340)), hemagglutinin (HA; YPYDVPDYA (SEQ ID NO:341)), glutathione-S-transferase (GST), or maltose-binding protein (MBP)) for use in purifying the antibodies or fragments. Heterologous polypeptides also include polypeptides (e.g., enzymes) that are useful as diagnostic or detectable markers, for example, luciferase, a fluorescent protein (e.g., green fluorescent protein (GFP)), or chloramphenicol acetyl transferase (CAT). Suitable radioactive labels include, e.g.,  32 P,  33 P,  14 C,  125 I,  131 I,  35 S, and  3 H. Suitable fluorescent labels include, without limitation, fluorescein, fluorescein isothiocyanate (FITC), green fluorescent protein (GFP), DyLight™ 488, phycoerythrin (PE), propidium iodide (PI), PerCP, PE-Alexa Fluor® 700, Cy5, allophycocyanin, and Cy7. Luminescent labels include, e.g., any of a variety of luminescent lanthanide (e.g., europium or terbium) chelates. For example, suitable europium chelates include the europium chelate of diethylene triamine pentaacetic acid (DTPA) or tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA). Enzymatic labels include, e.g., alkaline phosphatase, CAT, luciferase, and horseradish peroxidase. Another labeling technique which may result in greater sensitivity consists of coupling the antibodies to low molecular weight haptens. These haptens can then be specifically altered by means of a second reaction. For example, it is common to use haptens such as biotin, which reacts with avidin, or dinitrophenol, pyridoxal, or fluorescein, which can react with specific antihapten antibodies. 
     Two proteins (e.g., an antibody and a heterologous moiety) can be cross-linked using any of a number of known chemical cross linkers. Examples of such cross linkers are those that link two amino acid residues via a linkage that includes a “hindered” disulfide bond. In these linkages, a disulfide bond within the cross-linking unit is protected (by hindering groups on either side of the disulfide bond) from reduction by the action, for example, of reduced glutathione or the enzyme disulfide reductase. One suitable reagent, 4-succinimidyloxycarbonyl-α-methyl-α(2-pyridyldithio) toluene (SHPT), forms such a linkage between two proteins utilizing a terminal lysine on one of the proteins and a terminal cysteine on the other. Heterobifunctional reagents that cross-link by a different coupling moiety on each protein can also be used. Other useful cross-linkers include, without limitation, reagents which link two amino groups (e.g., N-5-azido-2-nitrobenzoyloxysuccinimide), two sulfhydryl groups (e.g., 1,4-bis-maleimidobutane), an amino group and a sulfhydryl group (e.g., m-maleimidobenzoyl-N-hydroxysuccinimide ester), an amino group and a carboxyl group (e.g., 4-[p-azidosalicylamido]butylamine), and an amino group and a guanidinium group that is present in the side chain of arginine (e.g., p-azidophenyl glyoxal monohydrate). 
     In some embodiments, a radioactive label can be directly conjugated to the amino acid backbone of the antibody. Alternatively, the radioactive label can be included as part of a larger molecule (e.g.,  125 I in meta-[ 125 I]iodophenyl-N-hydroxysuccinimide ([ 125 I]mIPNHS), which binds to free amino groups to form meta-iodophenyl (mIP) derivatives of relevant proteins (see, e.g., Rogers et al. (1997)  J Nucl Med  38:1221-1229) or chelate (e.g., to DOTA or DTPA), which is in turn bound to the protein backbone. Methods of conjugating the radioactive labels or larger molecules/chelates containing them to the antibodies or antigen binding fragments described herein are known in the art. Such methods involve incubating the proteins with the radioactive label under conditions (e.g., pH, salt concentration, and/or temperature) that facilitate binding of the radioactive label or chelate to the protein (see, e.g., U.S. Pat. No. 6,001,329). 
     Methods for conjugating a fluorescent label (sometimes referred to as a fluorophore) to a protein (e.g., an antibody) are known in the art of protein chemistry. For example, fluorophores can be conjugated to free amino groups (e.g., of lysines) or sulfhydryl groups (e.g., cysteines) of proteins using succinimidyl (NHS) ester or tetrafluorophenyl (TFP) ester moieties attached to the fluorophores. In some embodiments, the fluorophores can be conjugated to a heterobifunctional cross-linker moiety such as sulfo-SMCC. Suitable conjugation methods involve incubating an antibody protein or fragment thereof with the fluorophore under conditions that facilitate binding of the fluorophore to the protein. See, e.g., Welch and Redvanly (2003)  Handbook of Radiopharmaceuticals: Radiochemistry and Applications , John Wiley and Sons. 
     In some embodiments, the antibodies or fragments can be modified, e.g., with a moiety that improves the stabilization and/or retention of the antibodies in circulation, e.g., in blood, serum, or other tissues. For example, the antibody or fragment can be PEGylated as described in, e.g., Lee et al. (1999)  Bioconjug Chem  10(6): 973-8; Kinstler et al. (2002)  Advanced Drug Deliveries Reviews  54:477-485; and Roberts et al, (2002)  Advanced Drug Delivery Reviews  54:459-476, or HESylated (Fresenius Kabi, Germany) (see, e.g., Pavisić et al. (2010)  Int J Pharm  387(1-2):110-119). The stabilization moiety can improve the stability, or retention of, the antibody (or fragment) by at least 1.5 (e.g., at least 2, 5, 10, 15, 20, 25, 30, 40, or 50 or more) fold. 
     In some embodiments, the antibodies or antigen-binding fragments thereof described herein can be glycosylated. In some embodiments, an antibody or antigen-binding fragment thereof described herein can be subjected to enzymatic or chemical treatment, or produced from a cell, such that the antibody or fragment has reduced or absent glycosylation. Methods for producing antibodies with reduced glycosylation are known in the art and described in, e.g., U.S. Pat. No. 6,933,368; Wright et al. (1991)  EMBO J  10(10):2717-2723; and Co et al. (1993)  Mol Immunol  30:1361. 
     The materials for use in the assay of the disclosure are ideally suited for the preparation of a kit. Such a kit may comprise a carrier means being compartmentalized to receive in close confinement one or more container means such as vials, tubes, and the like, each of the container means comprising one of the separate elements to be used in the method. For example, one of the container means may comprise a monoclonal antibody of the invention that is, or can be, detectably labeled. The kit may also have containers containing buffer(s) and/or a container comprising a reporter-means, such as a biotin-binding protein, such as avidin or streptavidin, bound to a reporter molecule, such as an enzymatic or fluorescent label.

In certain embodiments, such compositions may influence the physical state, stability, rate of in vivo release and/or rate of in vivo clearance of the Dengue virus antigen-specific antibody or antigen binding fragment thereof. 
     In certain embodiments, the primary vehicle or carrier in a pharmaceutical composition can be either aqueous or non-aqueous in nature. For example, in certain embodiments, a suitable vehicle or carrier can be water for injection, physiological saline solution or artificial cerebrospinal fluid, possibly supplemented with other materials common in compositions for parenteral administration. In certain embodiments, the saline comprises isotonic phosphate-buffered saline. In certain embodiments, neutral buffered saline or saline mixed with serum albumin are further exemplary vehicles. In certain embodiments, pharmaceutical compositions comprise a pH controlling buffer such phosphate-buffered saline or acetate-buffered saline. In certain embodiments, a composition comprising a Dengue virus antigen-specific antibody or antigen binding fragment thereof disclosed herein can be prepared for storage by mixing the selected composition having the desired degree of purity with optional formulation agents (see Allen (2012)  Remington—The Science and Practice of Pharmacy,  22d Edition, Lloyd V, Allen, ed., The Pharmaceutical Press) in the form of a lyophilized cake or an aqueous solution. Further, in certain embodiments, a composition comprising a Dengue virus antigen-specific antibody or antigen binding fragment thereof disclosed herein can be formulated as a lyophilizate using appropriate excipients. In some instances, appropriate excipients may include a cryo-preservative, a bulking agent, a surfactant, or a combination of any thereof. Exemplary excipients include one or more of a polyol, a disaccharide, or a polysaccharide, such as, for example, mannitol, sorbitol, sucrose, trehalose, and dextran 40. In some instances, the cryo-preservative may be sucrose or trehalose. In some instances, the bulking agent may be glycine or mannitol. In one example, the surfactant may be a polysorbate such as, for example, polysorbate-20 or polysorbate-80. 
     In certain embodiments, the pharmaceutical composition can be selected for parenteral delivery. In certain embodiments, the compositions can be selected for inhalation or for delivery through the digestive tract, such as orally. The preparation of such pharmaceutically acceptable compositions is within the ability of one skilled in the art. 
     In certain embodiments, the formulation components are present in concentrations that are acceptable to the site of administration. In certain embodiments, buffers are used to maintain the composition at physiological pH or at a slightly lower pH, typically within a pH range of from about 5 to about 8. For example, the pH may be 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, 5.9, 6.0, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8. 6.9, 6.9, 7.0, 7.1, 7.2, 7.3, 7.4, 7.5, 7.6, 7.7, 7.8, 7.9, 8.0, 8.1, 8.2, 8.3, 8.4, or 8.5. In some instances, the pH of the pharmaceutical composition may be in the range of 6.6-8.5 such as, for example, 7.0-8.5, 6.6-7.2, 6.8-7.2, 6.8-7.4, 7.2-7.8, 7.0-7.5, 7.5-8.0, 7.2-8.2, 7.6-8.5, or 7.8-8.3. In some instances, the pH of the pharmaceutical composition may be in the range of 5.5-7.5 such as, for example, 5.5-5.8, 5.5-6.0, 5.7-6.2, 5.8-6.5, 6.0-6.5, 6.2-6.8, 6.5-7.0, 6.8-7.2, or 6.8-7.5. In some instances, the pH of the pharmaceutical composition may be in the range of 4.0-5.5 such as, for example, 4.0-4.3, 4.0-4.5, 4.2-4.8, 4.5-4.8, 4.5-5.0, 4.8-5.2, or 5.0-5.5. 
     In certain embodiments when parenteral administration is contemplated, a therapeutic composition can be in the form of a pyrogen-free, parenterally acceptable aqueous solution comprising a Dengue virus antigen-specific antibody or antigen binding fragment thereof in a pharmaceutically acceptable vehicle. In certain embodiments, a vehicle for parenteral injection is sterile distilled water in which a Dengue virus antigen-specific antibody or antigen binding fragment thereof is formulated as a sterile, isotonic solution and properly preserved. In certain embodiments, the preparation can involve the formulation of the desired molecule with an agent, such as injectable microspheres, bio-erodible particles, polymeric compounds (such as polylactic acid or polyglycolic acid), beads or liposomes, that can provide for the controlled or sustained release of the product which can then be delivered via a depot injection. In certain embodiments, hyaluronic acid can also be used, and can have the effect of promoting sustained duration in the circulation. In certain embodiments, implantable drug delivery devices can be used to introduce the desired molecule. 
     In certain embodiments, a pharmaceutical composition can be formulated for inhalation. In certain embodiments, a Dengue virus antigen-specific antibody or antigen binding fragment thereof can be formulated as a dry powder for inhalation. In certain embodiments, an inhalation solution comprising a Dengue virus antigen-specific antibody or antigen binding fragment thereof can be formulated with a propellant for aerosol delivery. In certain embodiments, solutions can be nebulized. Pulmonary administration is further described in International Application Publication No. WO/1994/020069, which describes pulmonary delivery of chemically modified proteins. 
     In certain embodiments, it is contemplated that formulations can be administered orally. In certain embodiments, a Dengue virus antigen-specific antibody or antigen binding fragment thereof that is administered in this fashion can be formulated with or without carriers customarily used in compounding solid dosage forms, such as tablets and capsules. In certain embodiments, a capsule can be designed to release the active portion of the formulation at the point in the gastrointestinal tract when bioavailability is maximized and pre-systemic degradation is minimized. In certain embodiments, at least one additional agent can be included to facilitate absorption of a Dengue virus antigen-specific antibody or antigen binding fragment thereof. In certain embodiments, diluents, flavorings, low melting point waxes, vegetable oils, lubricants, suspending agents, tablet disintegrating agents, and binders can also be employed. 
     In certain embodiments, a pharmaceutical composition can involve an effective quantity of a Dengue virus antigen-specific antibody or antigen binding fragment thereof in a mixture with non-toxic excipients suitable for the manufacture of tablets. In certain embodiments, by dissolving the tablets in sterile water or other appropriate vehicle, solutions can be prepared in unit-dose form. In certain embodiments, suitable excipients include, but are not limited to, inert diluents, such as calcium carbonate, sodium carbonate or bicarbonate, lactose, or calcium phosphate; or binding agents, such as starch, gelatin, or acacia; or lubricating agents such as magnesium stearate, stearic acid, or talc. 
     Additional pharmaceutical compositions can be selected by one skilled in the art, including formulations involving a Dengue virus antigen-specific antibody or antigen binding fragment thereof in sustained- or controlled-delivery formulations. In certain embodiments, techniques for formulating a variety of other sustained- or controlled-delivery means, such as liposome carriers, bio-erodible microparticles or porous beads and depot injections, are also known to those skilled in the art. See for example, International Application Publication No. WO/1993/015722, which describes the controlled release of porous polymeric microparticles for the delivery of pharmaceutical compositions. In certain embodiments, sustained-release preparations can include semipermeable polymer matrices in the form of shaped articles, e.g., films, or microcapsules. Sustained release matrices can include polyesters, hydrogels, polylactides (see, e.g., U.S. Pat. Nos. 3,773,919; 5,594,091; 8,383,153; 4,767,628; International Application Publication No. WO1998043615, Cabo, E. et al. (201:5)  Eur. Polymer J  65:252-267 and European Patent No. EP 058,481), including, for example, chemically synthesized polymers, starch based polymers, and polyhydmxyalkanoates (PHAs), copolymers of L-glutamic acid and gamma ethyl-L-glutamate (Sidman et al. (1993)  Biopolymers  22:547-556), poly (2-hydroxyethyl-methacrylate) (Langer et al. (1981)  J Biomed Mater Res.  15: 167-277; and Langer (1982)  Chem Tech  12:98-105), ethylene vinyl acetate (Hsu and Langer (1985)  J Biomed Materials Res  19(4):445-460) or poly-D(−)-3-hydroxybutyric acid (European Patent No. EP0133988). In certain embodiments, sustained release compositions can also include liposomes, which can be prepared by any of several methods known in the art. (See, e.g., Eppstein et al. (1985)  Prot. Natl. Acad. Sci. USA  82:3688-3692; European Patent No. EP 036,676; and U.S. Pat. Nos. 4,619,794 and 4,615,885). 
     The pharmaceutical composition to be used for in vivo administration typically is sterile. In certain embodiments, sterilization is accomplished by filtration through sterile filtration membranes. In certain embodiments, where the composition is lyophilized, sterilization using this method can be conducted either prior to or following lyophilization and reconstitution. In certain embodiments, the composition for parenteral administration can be stored in lyophilized form or in a solution. In certain embodiments, parenteral compositions generally are placed into a container having a sterile access port, for example, an intravenous solution bag or vial having a stopper pierceable by a hypodermic injection needle. 
     In certain embodiments, once the pharmaceutical composition has been formulated, it can be stored in sterile vials as a solution, suspension, gel, emulsion, solid, or as a dehydrated or lyophilized powder. In certain embodiments, such formulations can be stored either in a ready-to-use form or in a form (e.g., lyophilized) that is reconstituted prior to administration. 
     In certain embodiments, kits are provided for producing a single-dose administration unit. In certain embodiments, the kit can contain both a first container having a dried protein and a second container having an aqueous formulation. In certain embodiments, kits containing single and multi-chambered pre-filled syringes are included. 
     In certain embodiments, the effective amount of a pharmaceutical composition comprising a Dengue virus antigen-specific antibody or antigen binding fragment thereof to be employed therapeutically depends, for example, upon the therapeutic context and objectives. One skilled in the art will appreciate that the appropriate dosage levels for treatment, according to certain embodiments, vary depending, in part, upon the molecule delivered, the indication for which a Dengue virus antigen-specific antibody or antigen binding fragment thereof is being used, the route of administration, and the size (body weight, body surface or organ size) and/or condition (the age and general health) of the patient. The clinician can titer the dosage and modify the route of administration to obtain the optimal therapeutic effect. 
     The clinician also selects the frequency of dosing, taking into account the pharmacokinetic parameters of the Dengue virus antigen-specific antibody or antigen binding fragment thereof in the formulation used. In certain embodiments, a clinician administers the composition until a dosage is reached that achieves the desired effect. In certain embodiments, the composition can therefore be administered as a single dose or as two or more doses (which may or may not contain the same amount of the desired molecule) over time, or as a continuous infusion via, for example, an implantation device or catheter. Further refinement of the appropriate dosage is routinely made by those of ordinary skill in the art and is within the ambit of tasks routinely performed by them. In certain embodiments, appropriate dosages can be ascertained through use of appropriate dose-response data. 
     In certain embodiments, the route of administration of the pharmaceutical composition is in accord with known methods, e.g. orally, through injection by intravenous, intraperitoneal, intracerebral (intra-parenchymal), intracerebral, intraventricular, intramuscular, subcutaneously, intra-ocular, intraarterial, intraportal, or intralesional routes; by sustained release systems or by implantation devices. In certain embodiments, the compositions can be administered by bolus injection or continuously by infusion, or by implantation device. In certain embodiments, individual elements of a combination therapy may be administered by different routes. 
     In certain embodiments, the composition can be administered locally, e.g., during surgery or topically. Optionally local administration is via implantation of a membrane, sponge, or another appropriate material onto which the desired molecule has been absorbed or encapsulated. In certain embodiments, where an implantation device is used, the device can be implanted into any suitable tissue or organ, and delivery of the desired molecule can be via diffusion, timed-release bolus, or continuous administration. 
     In certain embodiments, it can be desirable to use a pharmaceutical composition comprising a Dengue virus antigen-specific antibody or antigen binding fragment thereof in an ex vivo manner. In such instances, cells that have been removed from a subject may be exposed to a pharmaceutical composition comprising a Dengue virus antigen-specific antibody or antigen binding fragment thereof after which the cells are subsequently implanted back into the subject. 
     In certain embodiments, a Dengue virus antigen-specific antibody or antigen binding fragment thereof can be delivered by implanting certain cells that have been genetically engineered, using methods such as those described herein, to express and secrete the polypeptides. In certain embodiments, such cells can be animal or human cells, and can be autologous, heterologous, or xenogeneic. In certain embodiments, the cells can be immortalized. In certain embodiments, in order to decrease the chance of an immunological response, the cells can be encapsulated to avoid infiltration of surrounding tissues. In certain embodiments, the encapsulation materials are typically biocompatible, semi-permeable polymeric enclosures or membranes that allow the release of the protein product(s) but prevent the destruction of the cells by a subject&#39;s immune system or by other detrimental factors from the surrounding tissues. 
     F. Method of Use of Dengue Virus Antigen-Specific Antibodies 
     1. In Vitro Detection and Diagnostics 
     The Dengue virus antigen-specific antibody or antigen binding fragment thereof provided in this disclosure are suited for in vitro use, for example, in immunoassays in which they can be utilized in liquid phase or bound to a solid phase carrier. In addition, the in these immunoassays can be detectably labeled in various ways. Examples of types of immunoassays which can utilize the monoclonal antibodies of the invention are competitive and non-competitive immunoassays in either a direct or indirect format. Examples of such immunoassays are the radioimmunoassay (RIA) and the sandwich (immunometric) assay. Detection of antigens using the monoclonal antibodies of the invention can be done utilizing immunoassays which are run in either the forward, reverse, or simultaneous modes, including immunohistochemical assays on physiological samples. Those of skill in the art will know, or can readily discern, other immunoassay formats without undue experimentation. 
     The monoclonal antibodies of the invention can be bound to many different carriers and used to detect the presence of dengue virus. Examples of well-known carriers include glass, polystyrene, polypropylene, polyethylene, dextran, nylon, amylase, natural and modified cellulose, polyacrylamide, agarose and magnetite. The nature of the carrier can be either soluble or insoluble for purposes of the invention. Those skilled in the art will know of other suitable carriers for binding monoclonal antibodies, or will be able to ascertain such, using routine experimentation. 
     For purposes of this disclosure, Dengue virus may be detected by the provided antibodies fragments thereof when the virus is present in biological fluids and tissues from a subject that may be infected with Dengue virus. Any sample containing a detectable amount of Dengue virus can be used. A sample can be a liquid such as urine, saliva, cerebrospinal fluid, blood, serum or the like; a solid or semi-solid such as tissues, feces, or the like; or, alternatively, a solid tissue such as those commonly used in histological diagnosis. 
     Another approach to assessing whether a subject is infected with Dengue virus is to determine if the B cell receptor (BCR) repertoire of the subject includes a coding sequence for one of the Dengue specific antibodies provided in this disclosure. An exemplary method of this type of sequence analysis is described in Example 13. RNA from whole blood or B cells (PBMCs) can be used as the template for the amplification of CDR sequences. CDRs of the heavy chain, light chain, or both may be sequenced, with analysis of either or both of lambda or kappa chain sequences. Primer pools are designed to result in wide-spread amplification of the BCR V(D)JC sequences in the sample. Reverse transcription is then performed to create cDNA sequences corresponding to the BCR coding sequences, which may be amplified for subsequent sequence analysis. Next generation sequencing of the amplified cDNA library can then be performed. Sequence analysis is used to assess the identity of the BCR V(D)JC sequences in the sample and to determine the percent identity thereof to the Dengue specific antibodies described herein. Various commercial services are also available for performing BCR repertoire analysis (e.g., Magic™ BCR Repertoire Analysis by Creative Biolabs). The presence of BCR sequences encoding the Dengue specific antibodies described in this disclosure in the subject&#39;s sample is indicative that the subject has a Dengue virus infection or has previously been exposed to Dengue virus. 
     2. In Vivo Detection 
     In using the provided antibodies and fragments thereof for the in vivo detection of Dengue virus antigens, the detectably labeled antibody or fragment thereof is given in a dose which is diagnostically effective. The term “diagnostically effective” means that the amount of detectably labeled monoclonal antibody is administered in sufficient quantity to enable detection of the site having the Dengue virus antigen for which the antibodies are specific. 
     The concentration of detectably labeled antibody or fragment thereof which is administered should be sufficient such that the binding to Dengue virus is detectable compared to the background. Further, it is desirable that the detectably labeled antibody or fragment thereof be rapidly cleared from the circulatory system in order to give the best target-to-background signal ratio. 
     As a rule, the dosage of detectably labeled antibody or fragment thereof for in vivo diagnosis will vary depending on such factors as age, sex, and extent of disease of the individual. The dosage of monoclonal antibody can vary from about 0.01 mg/kg to about 50 mg/kg, preferably 0.1 mg/kg to about 20 mg/kg, most preferably about 0.1 mg/kg to about 2 mg/kg. Such dosages may vary, for example, depending on whether multiple injections are given, on the tissue being assayed, and other factors known to those of skill in the art. 
     For in vivo diagnostic imaging, the type of detection instrument available is a major factor in selecting an appropriate radioisotope. The radioisotope chosen must have a type of decay which is detectable for the given type of instrument. Still another important factor in selecting a radioisotope for in vivo diagnosis is that the half-life of the radioisotope be long enough such that it is still detectable at the time of maximum uptake by the target, but short enough such that deleterious radiation with respect to the host is acceptable. Ideally, a radioisotope used for in vivo imaging will lack a particle emission but produce a large number of photons in the 140-250 keV range, which may be readily detected by conventional gamma cameras. For in vivo diagnosis, radioisotopes may be bound to immunoglobulin either directly or indirectly by using an intermediate functional group. Intermediate functional groups which often are used to bind radioisotopes which exist as metallic ions are the bifunctional chelating agents such as diethylenetriaminepentacetic acid (DTPA) and ethylenediaminetetra-acetic acid (EDTA) and similar molecules. Typical examples of metallic ions which can be bound to the monoclonal antibodies of the invention are  111 In,  97 Ru,  67 Ga,  68 Ga,  72 As,  89 Zr and  201 Tl. 
     The Dengue virus antigen-specific antibodies and antigen binding fragments thereof can also be labeled with a paramagnetic isotope for purposes of in vivo diagnosis, as in magnetic resonance imaging (MRI) or electron spin resonance (ESR). In general, any conventional method for visualizing diagnostic imaging can be utilized. Usually gamma and positron emitting radioisotopes are used for camera imaging and paramagnetic isotopes for MRI. Elements which are particularly useful in such techniques include  157 Gd,  55 Mn,  162 Dy,  52 Cr and  56 Fe. 
     The provided antibodies and antigen binding fragments can be used in vitro and in vivo to monitor the course of Dengue virus disease therapy. Thus, for example, by measuring the increase or decrease in the number of cells infected with Dengue virus or changes in the concentration of Dengue virus present in the body or in various body fluids, it would be possible to determine whether a particular therapeutic regimen aimed at ameliorating Dengue virus disease is effective. 
     3. Therapeutic Methods 
     As described herein, the present disclosure provides a method of treating a subject infected with a Dengue virus, comprising administering to the subject a therapeutically effective amount of a Dengue virus antigen-specific antibody or antigen binding fragment thereof of the present disclosure. In some embodiments, the subject has or is determined to have a Dengue virus infection. 
     The Dengue virus antigen-specific antibodies and antigen binding fragments thereof can also be used as a prophylactic therapy for Dengue virus disease. The provided antibodies and fragments thereof may be used either in prophylactic and therapeutic administration as well as either by passive immunization with substantially purified polypeptide products and gene therapy by transfer of polynucleotide sequences encoding the product or part thereof. Thus, the provided antibodies and fragments thereof can be administered to high-risk subjects in order to lessen the likelihood and/or severity of Dengue virus disease or administered to subjects already evidencing active Dengue virus infection. 
     The compositions described herein are useful in, inter alia, methods for treating a Dengue virus infection in a subject. As used herein, the term subject means a mammalian subject. Exemplary subjects include, but are not limited to humans, monkeys, dogs, cats, mice, rats, cows, horses, camels, goats and sheep. In some embodiments, the subject is a human. In some embodiments, the subject has or is suspected to have a Dengue virus infection. In some embodiments, the subject is diagnosed with a Dengue virus infection. In some embodiments, the subject is a human that is suspected of having a Dengue virus infection. 
     As used herein, administer or administration refers to the act of injecting or otherwise physically delivering a substance as it exists outside the body (e.g., a Dengue virus antigen-specific antibody or antigen binding fragment provided herein or a construct encoding same) into a patient, such as by mucosal, intradermal, intravenous, intramuscular, subcutaneous delivery and/or any other method of physical delivery described herein or known in the art. When a disease, or a symptom thereof, is being treated, administration of the substance typically occurs after the onset of the disease or symptoms thereof. When a disease, or symptoms thereof, are being prevented, administration of the substance typically occurs before the onset of the disease or symptoms thereof. 
     The compositions can be administered to a subject, e.g., a human subject, using a variety of methods that depend, in part, on the route of administration. The route can be, e.g., intravenous injection or infusion (IV), subcutaneous injection (SC), intraperitoneal (IP) injection, intramuscular injection (IM), intradermal injection (ID), subcutaneous, transdermal, intracavity, oral, intracranial injection, or intrathecal injection (IT). The injection can be in a bolus or a continuous infusion. Techniques for preparing injectate or infusate delivery systems containing antibodies are well known to those of skill in the art. Generally, such systems should utilize components which will not significantly impair the biological properties of the antibodies, such as the paratope binding capacity (see, for example,  Remington&#39;s Pharmaceutical Sciences,  18th edition, 1990, Mack Publishing). Those of skill in the art can readily determine the various parameters and conditions for producing antibody injectates or infusates without resort to undue experimentation. 
     Administration can be achieved by, e.g., topical administration, local infusion, injection, or by means of an implant. The implant can be of a porous, non-porous, or gelatinous material, including membranes, such as sialastic membranes, or fibers. The implant can be configured for sustained or periodic release of the composition to the subject. See, e.g., U.S. Patent Application Publication No. 20080241223; U.S. Pat. Nos. 5,501,856; 5,164,188; 4,863,457; and 3,710,795. The composition can be delivered to the subject by way of an implantable device based on, e.g., diffusive, erodible, or convective systems, e.g., osmotic pumps, biodegradable implants, electrodiffusion systems, electroosmosis systems, vapor pressure pumps, electrolytic pumps, effervescent pumps, piezoelectric pumps, erosion-based systems, or electromechanical systems. In some embodiments, a Dengue virus antigen-specific antibody or antigen binding fragment of the present disclosure is therapeutically delivered to a subject by way of local administration. 
     Preparations for parenteral administration include sterile aqueous or non-aqueous solutions, suspensions, and emulsions. Examples of non-aqueous solvents are propylene glycol, polyethylene glycol, vegetable oils such as olive oil, and injectable organic esters such as ethyl oleate. Aqueous carriers include water, alcoholic/aqueous solutions, emulsions or suspensions, including saline and buffered media. Parenteral vehicles include sodium chloride solution, Ringer&#39;s dextrose, dextrose and sodium chloride, lactated Ringer&#39;s or fixed oils. Intravenous vehicles include fluid and nutrient replenishers, electrolyte replenishers (such as those based on Ringer&#39;s dextrose), and the like. Preservatives and other additives may also be present such as, for example, antimicrobials, anti-oxidants, chelating agents, and the like. 
     Treating or treatment of any disease or disorder refers to ameliorating a disease or disorder that exists in a subject or a symptom thereof. The term ameliorating refers to any therapeutically beneficial result in the treatment of a disease state, e.g., a Dengue virus infection, lessening in the severity or progression, promoting remission or durations of remission, or curing thereof. Thus, treating or treatment includes ameliorating at least one physical parameter or symptom. Treating or treatment includes modulating the disease or disorder, either physically (e.g., stabilization of a discernible symptom) or physiologically (e.g., stabilization of a physical parameter) or both. Treating or treatment includes delaying or preventing metastasis. Thus, in the disclosed methods, treatment can refer to a 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100% reduction in the severity of an established disease or condition or symptom of the disease or condition. For example, a method for treating a Dengue virus infection in a subject by administering an antibody as described in this disclosure is considered to be a treatment if there is a 10% reduction in one or more symptoms of the cancer in a subject as compared to a control. Thus the reduction can be a 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or any percent reduction in between 10% and 100% as compared to native or control levels. It is understood that treatment does not necessarily refer to a cure or complete ablation of the disease, condition, or symptoms of the disease or condition. 
     The principal symptoms of Dengue virus infection include high fever and at least two of the following: severe headache, severe eye pain (behind the eyes), joint pain, pain in muscles or bones or both, rash, mild bleeding manifestation (e.g., nose or gum bleed, petechiae, easy bruising), or low white cell count. Severe Dengue: virus disease includes one or more of severe abdominal pain, persistent vomiting, red spots or patches on skin, bleeding from nose or gums, vomiting blood, black tarry stools, drowsiness, irritability, pale skin, cold skin, clammy skin, or difficulty breathing. Dengue hemorrhagic fever (DHF) is characterized by a fever that lasts from 2 to 7 days, with general signs and symptoms consistent with Dengue fever. When the fever declines, warning signs may develop. This marks the beginning of a 24 to 48 hour period when the smallest blood vessels (capillaries) become excessively permeable (“leaky”), allowing the fluid component to escape from the blood vessels into the peritoneum (causing ascites) and pleural cavity (leading to pleural effusions). This may lead to failure of the circulatory system and shock, and possibly death without prompt, appropriate treatment. In addition, a subject with DHF has a low platelet count and hemorrhagic manifestations, tendency to bruise easily or have other types of skin hemorrhages, bleeding nose or gums, and possibly internal bleeding. 
     As used herein, a “prophylactically effective amount” of a Dengue virus antigen-specific antibody or antigen binding fragment thereof is a dosage large enough to produce the desired effect in the protection of individuals against dengue virus infection for a reasonable period of time, such as one to two months or longer following administration. A prophylactically effective amount is not, however, a dosage so large as to cause adverse side effects, such as hyperviscosity syndromes, pulmonary edema, congestive heart failure, and the like. Generally, a prophylactically effective amount may vary with the subject&#39;s age, condition, and sex, as well as the extent of the disease in the subject and can be determined by one of skill in the art. Other factors can include, e.g., other medical disorders concurrently or previously affecting the subject, the general health of the subject, the genetic disposition of the subject, diet, time of administration, rate of excretion, drug combination, and any other additional therapeutics that are administered to the subject. The dosage of the prophylactically effective amount may be adjusted by the individual physician or veterinarian in the event of any complication. In some instances, a prophylactically effective amount may vary from about 0.01 mg/kg to about 50 mg/kg, preferably from about 0.1 mg/kg to about 20 mg/kg, most preferably from about 0.2 mg/kg to about 2 mg/kg, in one or more administrations (priming and boosting). 
     As used herein, the term “therapeutically effective amount” or effective amount refers to an amount of a Dengue virus antigen-specific antibody or antigen binding fragment thereof that, when administered to a subject, is effective to treat a disease or disorder such that the symptoms of Dengue virus disease are ameliorated or the likelihood of infection is decreased. A therapeutically effective amount is not, however, a dosage so large as to cause adverse side effects, such as hyperviscosity syndromes, pulmonary edema, congestive heart failure, and the like. A suitable dose of an antibody or fragment thereof described herein, which dose is capable of treating a Dengue virus infection in a subject, can depend on a variety of factors including the particular construct used and whether it is used concomitantly with other therapeutic agents. For example, a different dose of a whole Dengue virus antigen-specific antibody may be required to treat a subject with a Dengue virus infection as compared to the dose of a fragment of a Dengue virus antigen-specific antibody (e.g., Fab′ antibody fragment) required to treat the same subject. Other factors affecting the dose administered to the subject include, e.g., the type or extent of the infection. For example, a subject that has had a previous Dengue virus infection may require administration of a different dosage of Dengue virus antigen-specific antibody or antigen binding fragment thereof than a subject who has not previously had a Dengue virus infection. Generally, a therapeutically effective amount may vary with the subject&#39;s age, condition, and sex, as well as the extent of the disease in the subject and can be determined by one of skill in the art. Other factors can include, e.g., other medical disorders concurrently or previously affecting the subject, the general health of the subject, the genetic disposition of the subject, diet, time of administration, rate of excretion, drug combination, and any other additional therapeutics that are administered to the subject. It should also be understood that a specific dosage and treatment regimen for any particular subject also depends upon the judgment of the treating medical practitioner (e.g., doctor or nurse). A therapeutically effective amount is also one in which any toxic or detrimental effects of the composition are outweighed by the therapeutically beneficial effects. The dosage of the therapeutically effective amount may be adjusted by the individual physician or veterinarian in the event of any complication. In some instances, a therapeutically effective amount may vary from about 0.01 mg/kg to about 50 mg/kg, preferably from about 0.1 mg/kg to about 20 mg/kg, most preferably from about 0.2 mg/kg to about 2 mg/kg, in one or more dose administrations daily, for one or several days. In some instances, the Dengue virus antigen-specific antibody or antigen binding fragment thereof is administered for 2 to 5 or more consecutive days in order to avoid “rebound” of virus replication from occurring. 
     A pharmaceutical composition can include a therapeutically effective amount or a prophylactically effective amount of a Dengue virus antigen-specific antibody or antigen binding fragment thereof described herein. Such effective amounts can be readily determined by one of ordinary skill in the art as described above. Considerations include the effect of the administered Dengue virus antigen-specific antibody or antigen binding fragment thereof, or the combinatorial effect of the Dengue virus antigen-specific antibody or antigen binding fragment thereof with one or more additional active agents, if more than one agent is used in or with the pharmaceutical composition. 
     Suitable human doses of any of the Dengue virus antigen-specific antibody or antigen binding fragment thereof described herein can further be evaluated in, e.g., Phase I dose escalation studies. See, e.g., van Gurp et al, (2008)  Am J Transplantation  8(8):1711-1718; Hanouska et al. (2007)  Clin Cancer Res  13(2, part 1):523-531; and Hetherington et al. (2006)  Antimicrobial Agents and Chemotherapy  50(10): 3499-3500. 
     Toxicity and therapeutic efficacy of such Dengue virus antigen-specific antibodies or antigen binding fragments thereof can be determined by known pharmaceutical procedures in cell cultures or experimental animals (e.g., animal models of any of the cancers described herein). These procedures can be used, e.g., for determining the LD 50  (the dose lethal to 50% of the population) and the ED 50  (the dose therapeutically effective in 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index, and it can be expressed as the ratio LD 50 /ED 50 . A Dengue virus antigen-specific antibody or antigen binding fragment thereof that exhibits a high therapeutic index is preferred. While constructs that exhibit toxic side effects may be used, care should be taken to design a delivery system that targets such constructs to the site of affected tissue and to minimize potential damage to normal cells and, thereby, reduce side effects. 
     The data obtained from the cell culture assays and animal studies can be used in formulating a range of dosage for use in humans. The dosage of a Dengue virus antigen-specific antibody or antigen binding fragment thereof lies generally within a range of circulating concentrations of the Dengue virus antigen-specific antibody or antigen binding fragment that include the ED 50  with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. For Dengue virus antigen-specific antibodies or antigen binding fragments thereof described herein, the therapeutically effective dose can be estimated initially from cell culture assays. A dose can be formulated in animal models to achieve a circulating plasma concentration range that includes the EC 50  (i.e., the concentration of the construct—e.g., antibody—which achieves a half-maximal inhibition of symptoms) as determined in cell culture. Such information can be used to more accurately determine useful doses in humans. Levels in plasma may be measured, for example, by high performance liquid chromatography. In some embodiments, e.g., where local administration is desired, cell culture or animal models can be used to determine a dose required to achieve a therapeutically effective concentration within the local site. 
     In some embodiments, a Dengue virus antigen-specific antibody or antigen binding fragment thereof described herein can be administered to a subject as a monotherapy. Alternatively, the Dengue virus antigen-specific antibody or antigen binding fragment thereof can be administered in conjunction with other therapies for viral infection (combination therapy). For example, the composition can be administered to a subject at the same time, prior to, or after, a second therapy. In some embodiments, the Dengue virus antigen-specific antibody or antigen binding fragment thereof and the one or more additional active agents are administered at the same time. Optionally, the Dengue virus antigen-specific antibody or antigen binding fragment thereof is administered first in time and the one or more additional active agents are administered second in time. In some embodiments, the one or more additional active agents are administered first in time and the Dengue virus antigen-specific antibody or antigen binding fragment thereof is administered second in time. Optionally, the Dengue virus antigen-specific antibody or antigen binding fragment thereof and the one or more additional agents are administered simultaneously in the same or different routes. For example, a composition comprising the Dengue virus antigen-specific antibody or antigen binding fragment thereof optionally contains one or more additional agents. 
     There is currently no specific medication approved for treatment of a Dengue virus infection. Subjects that may have a Dengue: virus infection are generally administered analgesics (pain relievers) with acetaminophen but generally not administered analgesics containing ibuprofen, naproxen, or aspirin or other aspirin containing drugs. There is also no specific medication for Severe Dengue (SD). If a clinical diagnosis is made early, a subject with SD may be treated using fluid replacement therapy. However, monoclonal antibody therapeutics, small molecule anti-viral drugs, peptide inhibitors, and gene therapy approaches are under development and known in the art and could be used in combination therapy with the Dengue virus antigen-specific antibodies or antigen binding fragments thereof described herein. Antiviral approaches explored thus far have targeted both structural and nonstructural proteins of Dengue virus. The search for small-molecule inhibitors that target viral entry has focused on the multifunctional enzymes NS3 and NS5 (see, e.g., Wang Q Y, et al. (2009)  Antimicrob Agents Chemother  53:1823-1831; Luo D, et al. (2015)  Antiviral Res  118:148-158; Schmidt et al. (2012)  PLoS Pathog  8:e1002627; de Wispelaere et al, (2018).  Cell Chem Biol  (https://doi.org/10.1016j.chembiol.2018.05.011) in press). In addition, the C protein and NS4B are also being explored as drug targets (see, e.g., Byrd C M, et al. (2013)  Antimicrob Agents Chemother  57:15-25; Becker G L, et al. (2012)  J Biol Chem  287:21992-2003; Scaturro P, et al. (2014)  J Virol  88:11540-11555; van Cleef K W, et al. (2013)  Antiviral Res  99:165-171). The most advanced therapeutics against virus entry are therapeutic antibodies, which are at various stages of clinical development (see, e.g., Robinson L N, et al. (2015)  Cell  162:493-504; Teoh E P, et al. (2012)  Sci Transl Med  4:139ra83). Peptide inhibitors are also under development. See, e.g.; Panya, A., et al. (2014) Chem Biol &amp; Drug Design 84(2):148-457. 
     A Dengue virus antigen-specific antibody or antigen binding fragment thereof described herein can replace or augment a previously or currently administered therapy. For example, upon treating with a Dengue virus antigen-specific antibody or antigen binding fragment thereof, administration of the one or more additional active agents can cease or diminish; e.g., be administered at lower levels or dosages. In some embodiments, administration of the previous therapy can be maintained. In some embodiments, a previous therapy is maintained until the level of the Dengue virus antigen-specific antibody or antigen binding fragment thereof reaches a level sufficient to provide a therapeutic effect. 
     Monitoring a subject (e.g., a human patient) for an improvement of a Dengue viral infection, as defined herein, means evaluating the subject for a change in a disease parameter, e.g., a reduction in one or more symptoms of Dengue virus infection exhibited by the subject. In some embodiments, the evaluation is performed at least one (1) hour, e.g., at least 2, 4, 6, 8, 12, 24, or 48 hours, or at least 1 day, 2 days, 4 days, 10 days, 13 days, 20 days or more, or at least 1 week. 2 weeks, 4 weeks, 10 weeks, 13 weeks, 20 weeks or more, after an administration. The subject can be evaluated in one or more of the following periods: prior to beginning of treatment; during the treatment; or after one or more elements of the treatment have been administered. Evaluation can include evaluating the need for further treatment, e.g., evaluating whether a dosage, frequency of administration, or duration of treatment should be altered. It can also include evaluating the need to add or drop a selected therapeutic modality, e.g., adding or dropping any of the treatments for a viral infection described herein. 
     EXAMPLES 
     Example 1. Virus-Inclusive Single Cell RNA Sequencing 
     Virus-inclusive single cell RNA-seq approach (viscRNA-Seq) was used to profile transcriptomes of thousands of single PBMCs derived early in the course of disease from six dengue patients and four healthy controls, and to characterize distinct DENV-associated leukocytes. viscRNA-Seq is an approach to sequence and quantify the whole transcriptome of single cells together with the viral RNA (vRNA) from the same cell. viscRNA-Seq permits investigation of virus-host interactions in an unbiased, high-throughput manner, keeping information on cell-to-cell variability (i.e. cell state) and creating statistical power by the large number of single cell replicates while avoiding essential gene restrictions. Using this method, gene expression may be correlated with virus level in the same cell. Use of this method is described in Zanini, F. et al. (2018)  eLIFE  7:e32942, which is incorporated herein in its entirety for all purposes. 
     In this study, FACS was coupled with viscRNA-Seq to identify virus-associated cells from human patients and studied the molecular signatures preceding the development of SD infection. The use of antibodies against surface proteins during FACS enabled enrichment for specific cell populations. Moreover, since viscRNA-Seq requires no genetic manipulation of the cells of interest, this approach enabled high-resolution screening of the whole human transcriptome for changes in gene expression at the single cell level. 
     A. Materials &amp; Methods 
     Colombia cohort ethics statement. All work with human subjects was approved by the Stanford University Administrative Panel on Human Subjects in Medical Research (Protocol 35460) and the Fundación Valle del Lili Ethics committee in biomedical research (Cali/Colombia). All subjects, their parents or legal guardians provided written informed consent, and subjects between 6 to 17 years of age and older provided assent. 
     Study population and sample collection. Blood samples were collected from individuals presenting to the emergency room or clinics at the Fundación Valle del LAE in Cali (Colombia) between March 2016 and June 2017. Enrollment criteria include: i) age greater than 2 years; ii) presentation with an acute febrile illness of less than 7 day duration associated with one or more of the following signs or symptoms: headache, rash, arthralgia, myalgia, retro-orbital pain, abdominal pain, positive tourniquet test, petechiae, and bleeding; and iii) a positive dengue IgM antibody and/or NS1 antigen by the SD BIOLINE Dengue Duo combo device (Standard Diagnostic Inc., Korea) (Wang and Sekaran, 2010). 
     Patients were classified by infectious diseases specialists as having dengue, dengue with warning signs or severe dengue according to 2009 WHO criteria [22,43] upon both presentation and prior to their discharge. Patients presenting with severe dengue were excluded from the study. Discharge diagnoses were also blindly classified by infectious diseases specialists according to the 1997 WHO criteria into DF, DHF, and/or DSS criteria. Demographics and clinical information were collected at the time of presentation. The first day of fever (fever day 0) was defined by the patients or their relatives. Symptoms, signs, and laboratory studies (including complete blood count, chemistry, and liver function tests) were documented by healthcare professionals. 
     The first venous blood sample was collected upon enrollment on the first day of presentation. 10-40 ml of whole blood were collected in 1-4 tubes. Serum samples were obtained for additional assays. Samples transport, reception, and processing were strictly controlled using personal data assistants (PDAs) with barcode scanners. 
     PBMCs isolation. PBMCs were isolated using SepMate tubes (Stemcell Technologies) according to the manufacturer&#39;s instructions. Briefly, whole blood was diluted 1:1 with phosphate-buffered saline (PBS) and added to a SepMate tube, which contained 15 ml of Ficoll. Tubes were then centrifuged for 10 minutes at 1,200 g, after which the PBMC layer was poured off into a fresh tube and washed with PBS. Tubes were then centrifuged at 250×g for 10 minutes and resuspended in freezing media. Cryovials containing PBMCs were then placed in a CoolCell at −80 C for 24 hours prior to being transferred to liquid nitrogen for storage. 
     Confirmation of dengue diagnosis—qRT-PCR assays for detection of dengue and other microbial pathogens. To confirm the diagnosis of dengue and differentiate from infection with the co-circulating arboviruses, Zika virus and chikungunya virus, serum samples were screened with a qualitative, single-reaction, multiplex real-time reverse transcriptase PCR (rRT-PCR) that detects Zika, chikungunya, and dengue virus RNA (Waggoner J J, et al. (2016)  Emerg Inject Dis.  22:1295-1297). To identify the specific DENV serotype and determine the virus load, samples positive for DENS&#39; in the screening assay were serotyped and quantitated using a separate DEW multiplex rRT-PCR (Waggoner J J. et al. (2013) PLoS Negl Trop Dis. 7:e2116). 
     Confirmation of dengue diagnosis—Multiplexed serological assays on a plasmonic-gold platform. Multiplexed antigen microarrays including DENV-2 whole virus particles spotted in triplicate were fabricated on pGOLD slides (Nirmidas Biotech, California) and serologic testing performed, as described (Zhang B, et al. (2017) Nat Med. 23:548-550). Briefly, for DEW IgG and IgM testing, each well was incubated with human sera (400 times dilution) for 40 min, followed by incubation of a mixture of anti-human IgG-IRDye680 conjugate and anti-human IgM-IRDye800 conjugate for 15 min (Vector-Laboratories, Burlingame, Calif.). Each well was washed between incubation procedures. The biochip was then scanned with a MidaScan-IR near-infrared scanner. IRDye680 and IRDye800 fluorescence images were generated, and the median fluorescence signal for each channel on each microarray spot was quantified by MidaScan software. For each sample, each antigen and each channel, the average of the three median fluorescence signals for three spots was calculated and normalized by positive and negative reference samples through a two-point calibration. Previously defined cutoffs based on mean levels+3 S.D. were used (Zhang B, et al. (2017)). DENV IgG avidity was performed as above in duplicate wells, except that following primary incubation, one well was incubated with 10 M urea for 10 min. Then, anti-human IgG-IRDye680 conjugate was applied to each well and incubated for 15 min. DENV IgG avidity was calculated by dividing the normalized DENV IgG result of the sample tested with urea treatment by the normalized DENV IgG result of the sample without urea treatment. High avidity (&gt;0.6) is indicative of a past infection, whereas low avidity (&lt;0.6) is consistent with a recent infection. 
     Fluorescence activated cell sorting. Cells were thawed in a water bath at 37° C. in media containing 10% DMSO. 9 ml of warm media were added and cells were spun 300 g×8 mins. The supernatant was discarded and 2 ml of media were added, then cells were spun again. The supernatant was discarded and cells were resuspend in 100 μl Phosphate Buffer solution (PBS) 1% BSA (bovine serum albumin). 5 μl of Human TruStain FcX™ (Fc Receptor Blocking Solution) from Biolegend were added and cells were incubated for 15 mins at room temperature. 300 μl of PBS were added for a total volume of 405 μl. The cell suspension was split in 3 or 4 aliquots (100 μl/aliquot, see below) and the specific antibody mix (3 μl/antibody, total ˜10-30 was added to each aliquot (see below). Cells were incubated for 45 mins on ice, then 1 ml PBS was added. 1 μl of SytoxBlue (ThermoFisher) was added to stain dead cells and the cells were incubated 5 mins at room temperature. Cells were filtered through a 35-40 μm filter into FACS tubes, 1 ml PBS was added (total volume ˜2 ml) and cells were flown on a Sony SH800 cell sorter with a 100 μm chip. When it became available, targeted mode for the calibration of the instrument was used. 
     Two sets of antibody panels were developed for this study. The first group of panels (Table 6a) was used for patient samples 3-013-1, 3-027-1, 1-008-1, 1-013-1, 1-020-1, 1-026-1, and 3-018-1, the second group (Table 6b) for patient samples 3-006-1, 1-010-1, 1-036-1. Colors for both sets of panels adhere as much as possible to the following design principles and are set forth in Table 6A and Table 6B:
         LINEAGED (violet/blue—noted by “1” below): Common negative selection for dead stain (sytox blue), CD235a (red blood cells), plus abundant cell types that are not in the focal aliquot. For instance, in the monocyte aliquot we want to exclude T, NK, and B cells.   ANCHOR (green—noted by “2” below): Common positive selection gate for the focal aliquot, so we can select blue− green+ and color bleeding is not such a big problem. For instance, CD2 is anchoring both T cells and NK cells.   SPECIFIC 1 (orange—noted by “3” below) and SPECIFIC 2 (infrared—noted by “4” below): Aliquot-specific antibodies that will be plotted against one another to distinguish 2 or more subpopulations.

     The expected ratio of abundances for the various cell types was generally observed: T cells were most abundant, followed in similar proportions by B cells, monocytes, and NK cells. Dendritic cells were less abundant. 
     viscRNA-Seq protocol. viscRNA-Seq was performed as described in Zanini, F. et al. (2018)  eLIFE  7:e32942. Briefly, 384-well (Biorad HSP384) lysis plates containing capture oligos for polyadenylated mRNA and a DENV-specific capture oligo were prepared beforehand and stored at −80 C and cells were sorted into them (lysis volume 0.5 μl). Reverse transcription, template switching and 23 cycles of PCR were done to generate and amplify the cDNA. On some plates, cDNA quantification was performed using the Quant-iT™ PicoGreen™ dsDNA Assay Kit (ThermoFisher) and normalization to 0.4 ng/ul was achieved using automated liquid handling robots. Sequencing libraries were prepared using the Nextera XT kit (illumina) or equivalent in-house reagents with 10-12 cycles of amplification after tagmentation. The DNA was purified using Ampure XP (Agencourt) magnetic beads at a ratio of 0.75-0.8× for two or three times in a row to ensure primer removal, and libraries were quantified on a Bioanalyzer 2100 (Agilent). 
     Sequencing. Libraries were sequenced on NextSeq 500 or NovaSeq machines (illumina) using 75 or 100 base paired-end reads, respectively. To avoid “index hopping” on the latter platform, 15,360 custom multiplex barcodes, developed at Chan Zuckerberg Biohub, were used to uniquely barcode both ends of the tagmented DNA, so that a double recombination event is required to generate cross contamination. See description of barcodes in Quake S R, et al. (2018)  Nature  562:367-372. Sequencing coverage was around 500,000 to 5,000,000 read pairs per cell. 
     Bioinformatics data analysis. Custom Python 3.6 scripts were used for the analysis and are available at github.com/iosonofabio/Zanini_et_al_DENV_patients_2018. The following software was routinely used for this study: numpy (van der Walt 5, et al. (2011)  Computing in Science Engineering  13: 22-30), seaborn (Waskom M, et al. seaborn: v0.5.0 (November 2014), available at doi:10.5281/zenodo.12710), and scikit-learn (Pedregosa F, et al. (2011)  J Mach Learn Res.  12: 2825-2830), and pandas (McKinney W. (2011) pandas: a Foundational Python Library for Data Analysis and Statistics, Python for High Performance and Scientific Computing, available at www.dlr.de/sc/Portaldata/15/Resources/dokumente/pyhpc2011/submissions/pyhpc2011_submission_9.pdf), and matplotlib (Hunter J D. (2007)  Comput Sci Eng  9:90-95). 
     Read mapping/assembling and gene counting. The sequencing reads were demultiplexed using bcl2fastq 2.19 (Illumina), mapped to the human genome reference GRCh38 from Ensembl augmented with ERCC spike-in controls using STAR aligner (Dobin A, et al. (2013)  Bioinformatics  29: 15-21). Human genes were counted using htseq-count from the HTSeq library (Anders S. et al. (2015)  Bioinformatics  31: 166-169), which is currently maintained by one of the inventors (F. Zanini). Unmapped reads were mapped to a serotype specific DENV reference using Stampy (Lunter G &amp; Goodson M. (2011)  Genome Res.  21:936-939) inside a singularity container (Kurtzer G M, et al. (2017)  PLoS One  12:e0177459) and filtered to trim short CIGAR sections off the read edges using custom Python scripts (see below), Filtered viral reads were assembled using vicuna (Yang X, et al. (2012)  BMC Genomics  13: 475) followed by a semi-automatic merge of the contigs onto the closest reference found by NCBI BLAST (i.e. a complete genome from the same serotype). Viral reads were then remapped against this hybrid reference and single nucleotide polymorphism frequencies were computed by custom scripts after trimming again short CIGAR codes off the read edges. 
     B and T cell receptor assembly and clonality graph construction. Sequencing reads belonging to cells within the B cluster were assembled into full length paired heavy and light chains using the guided de-novo assembler BASIC (Canzar S, et al. (2017) Bioinformatics 33:425-427). For each chain, the results of gene segment and CDR3 sequence IgBLAST v1.8.0 (Ye J, et al. (2013)  Nucleic Acids Res  41: W34-40) assignment were parsed with Change-O (Gupta N T, et al. (2015)  Bioinformatics  31:3356-3358) while a custom BLAST database (Camacho C, et al. (2009)  BMC Bioinformatics  10:421) of IMGT (Lefranc M-P, et al. (2009)  Nucleic Acids Res.  37:D1006-12) constant region sequences was used to determine heavy chain isotype and light chain type (lambda or kappa). Graph-tool (Peixoto T P. (2017), available at doi:10.6084/m9.figshare.1164194.v14) was used to draw clonal families, or “lineages”, comprised of heavy chain sequences grouped by identical V and J gene assignment, identical amino acid CDR3 length, and an 80% CDR3 amino acid sequence similarity. The grouping was “greedy” in that for a sequence to be grouped, it needed to have 80% sequence similarity with only one other sequence in that clonal family. Assembly of T cell receptors followed an identical process except using the appropriate T cell sequence databases for each step. Invariant NKT cells were identified by TRAV10-TRAJ18 TRBV25-1 gene usage, while MATT cells were identified by TRAV1-2-TRAJ12/20/33 gene usage. 
     Mapping of DENV reads. The non-human reads were mapped to a serotype-specific consensus using loose parameters to optimize for yield. The mapping reads were then assembled using a reference-aware virus assembler (Yang X, et al. (2012) BMC Genomics 13:475), the assembly was completed manually, and all virus reads were remapped from the two relevant patients against their own consensus sequence. 
     Data availability. All sequencing reads are available as NCBI Gene Expression Omnibus (GEO) Submission No, GSEI 16672. Each fastq.gz, BAM, or tsv file often is named or contains references to experiment IDs rather than patient sample names: the conversion between the two is shown in Table 11A, and Table 11B below. Whenever a 10 digit numberic ID starts with an experiment ID and is followed by two more digits, the last 2 digits refer to the 384-well plate the cells were sorted into. 
     In situ RNA hybridization. Single molecule in situ hybridization probes and buffers were acquired from LGC Biosearch technologies and performed according to the manufacturer&#39;s instructions. 32 probes conjugated to fluorescein against positive strand and 29 probes conjugated to FluorRed 610 against negative strand DENV2 16681 were designed to detect the viral RNA (see Supplementary File 2). For the B cell assays, PBMCs were isolated from a donor from the Stanford blood bank and B cells or naive B cells were isolated using the MACS B Cell Isolation Kit II, human (Milltenyi Biotech) or the Naive B Cell Isolation Kit II, human (Milltenyi Biotech), respectively. B cells were then incubated with DENV2 (strain 16681) for 48 hours. Positive and negative controls were performed on Human hepatoma (Huh7) cells, incubated with the same viral strain for 48 hours. After this time, 6 μl of cells were deposited onto a glass coverslip coated with poly-L-lysine, incubated for 5 minutes, fixed with 4% paraformaldehyde, washed, and hybridized for 4-16 hours with the probes. SlowFadem™ Gold Antifade Mountant with DAPI was used as mounting liquid. Imaging was performed on a Leica DMI6000B microscope with a 63× oil immersion objective (NA 1.40). 
     B. Results 
     High-dimensional profiling of single cells from dengue virus infected patients. FACS was combined with viscRNA-Seq to profile the host and viral transcriptomes in peripheral mononuclear blood cells (PBMCs) collected early in the course of natural dengue infection in humans. Blood samples were derived from the Colombia cohort—four healthy control subjects and six DEW infected patients, two who experienced an uncomplicated disease course and four who subsequently progressed to SD (see Table 7).

     All subjects were prospectively enrolled to a cohort that we established in Colombia (“Colombia cohort”). Subject information is shown in Table 8 and Tables 9A-9D. Disease severity was classified on-site using the criteria set forth in the World Health Organization 2009 Dengue: Guidelines for Diagnosis, Treatment, Prevention and Control. World Health Organization upon presentation and discharge. Patients were enrolled within 2-5 days after symptoms onset based on clinical presentation compatible with dengue or dengue with warning signs and positive NS1 antigen and/or anti-DENV IgM antibody. Notably, patients presenting with SD were excluded. Whole blood and serum samples were obtained upon presentation. qRT-PCR and serological assays confirmed the diagnosis of DENV infection and excluded other arboviral infections (including Zika and chikungunya). IgG avidity testing distinguished primary from secondary dengue (Table 8). PBMC samples were isolated, stored and shipped in liquid nitrogen.

     To sort multiple types of immune cells in patient PBMC samples and enable viscRNA-Seq with high specificity and throughput, two panels of antibodies against host cell surface markers were assembled as described above. The PBMC samples were split into several aliquots, immunostained, and sorted via. FACS into T cells, natural killer (NK) cells, B cells, monocytes, and dendritic (DC) cells (markers used listed in Table 10A; antibodies used listed in Table 10B; FACS data not shown),

     The viscRNA-Seq protocol was then followed, and each cell was sequenced at a depth of ˜1 million reads on NextSeq 500 and NovaSeq (Illumina) instruments. To measure intracellular DENV RNA abundance, we conducted viscRNA-Seq using the previously reported pan-DENV capture oligo as described previously in Zanini, F. et al. (2018)  eLIFE  7:e32942. The information provided by this approach on each individual cell included the cell type, immune activation state, infection state (whether and how much DEW RNA the cell contains), and sequence of the virus strain. 
     FACS-assisted viscRNA-Seq captures multiple cell types and activation states. Most human tissues including blood present a skewed composition of cell types. Unbiased cell capture, as routinely done in microfluidics protocols, produces detailed data on the most abundant cell populations, but fails to represent rare cell populations. To overcome this limitation, FACS was combined with a plate-based protocol to capture immune cells from samples containing less than 1,000,000 cells (because cells are sorted directly into single wells) with high sensitivity (as assessed by CD45 expression), and adequate representation of various cell populations ( FIG. 1A ) (Zanini F. &amp; lishknn, E, (2018) Stanford University, available at github.com/iosonofabio/shknn; Carnevali P. (2018) ExpressionMatrix2, Chan Zuckerberg Initiative; available at github.com/chanzuckerberg/ExpressionMatrix2). In total, over 13,000 cells were sequenced, of which several hundred showed robust signal for DEN′ RNA ( FIG. 1A ). Following quality filtering, tens to hundreds of cells were analyzed for most cell types of each sample, for a total of ˜8,700 cells ( FIG. 1B ). Within each cell type, multiple distinct overlapping immune cell subtypes and cell states were well represented in the dataset (see  FIG. 1C , Table 114, and Table 11B), For Table 11A and Table 11B, because fluorescent antibodies were used to enrich certain populations, these abundances do not directly reflect the fraction of cell types in the subjects&#39; blood. These tables also contain experiment ID (used in the sequencing files) and diagnosis In particular, within B cells alone many naive, IgM/IGD double positive cells were profiled as well as isotype switched cells. Most B cells formed a continuum of differentiation, but two additional clusters were also identified: the first expressed markers of plasmablasts and plasma cells, whereas the second showed high expression of TYROBP, a transmembrane signalling protein that has been implicated in B cell proliferation.

     Profiling single cell gene expression identifies candidate predictive biomarkers of severe dengue infection. The host transcriptome responses in the various PBMC populations were profiled. As blood samples were obtained early in the course of dengue infection, this analysis was aimed at revealing alterations in gene expression that preceded the progression to SD. For each cell subtype and gene, the distribution of expression values was compared across the three categories of subjects: healthy control (H); uncomplicated dengue (D), and severe dengue (SD). To identify differentially expressed genes, a two-sample Kolmogorov-Smirnov test was used together with a computation of fold change in the averages across cells. Several genes whose expression was strongly upregulated early in the course of infection in subjects that subsequently progressed to SD were identified. Many of these genes belonged to the antiviral interferon response, yet they were upregulated in a cell type specific manner ( FIG. 2A ). Some genes were expressed in multiple cell types but were upregulated more strongly in specific cells from SD subjects ( FIG. 2B ); other genes were expressed essentially only during SD except in a few cell types ( FIG. 2C ); a few genes were expressed only in one cell type and only in subjects who subsequently developed SD (e.g. CD163 in monocytes,  FIG. 2D ). These results indicate that distinct cell populations respond differently to the same viral infection, confounding the performance of bulk assays, such as microarrays. Since this heterogeneity is not a hindrance but rather a resource within the single cell approach, the predictive potential of gene expression in specific cell types was explored. To do so, cells within the same patient and cell population were averaged and binary classification of severity at increasing thresholds of expression was tested, de facto simulating a pseudo-bulk assay that could be implemented in the clinic. A number of genes were identified in specific cell populations that showed great predictive power for distinguishing SD from other subjects, as assessed by receiver operating characteristic (ROC) curves ( FIG. 2E ). Two notable examples with optimal ROC performance (area under the curve=1) are MX2 in naive B lymphocytes and CD163 m double positive CD14 + /CD16 +  monocytes. 
     Virus in severe dengue patients is primarily associated with naive B cells. To define the cell subtypes that are associated with DENV in the PBMC samples, cells with viral RNA reads were focused on. Viral reads were detected in two samples only (out of six dengue confirmed samples analyzed), both of which were derived from subjects who had high viral loads in their serum and that subsequently progressed to SD (samples 1-026-1 and 1-036-1, see Tables 9A-9D). In both samples, a small number of monocytes were associated with viral RNA. A weak upregulation of CD4, EXT1, GPR132, ZIMZ1, SLC27A3, MUCL1, SFPQ, NFIL3, NBPF9, GAB3, PSG2, and NBPF15 was observed in these virus-associated monocytes (data not shown). Downregulated genes were AC090498.1, PSME2P6, GADH, DLG1, MBNL1, EXOC6, CLEC12A, PTBP3, and SOD1 (data not shown). The majority of virus-associated cells were B lymphocytes ( FIG. 3A ). No viral reads were detected in other types of leukocytes. These findings are in line with a previous report based on bulk qPCR assays (Srikiatkhachorn A, et al. (2012)  PLoS One  7:e51335). The fraction of uniquely mapped reads corresponding to viral RNA in those cells was heterogeneous but generally 1% or less, corresponding to several hundred reads per cell but much lower than was measured in cultured Huh7 cells as described by Zanini, F. et al. (2018)  eLIFE  7:e32942. 
     To determine whether a distinct subpopulation of B cells was specifically associated with DENV, the most upregulated genes in the virus-associated population versus other B cells from the same patients were identified. DENV-associated B cells were enriched but not exclusive to IgM/IGD isotypes as well as other markers of naive B lymphocytes, such as the transcription factor TCL1A. The surface receptors CD69, FCRL1, and CXCR4 that signal B cell activation and tissue-specific homing, and IRF1 that encodes an interferon related protein were also upregulated ( FIG. 3B ). A 2-dimensional embedding of the B cells via t-Distributed Stochastic Neighbor Embedding (tSNE) was identified from the two PBMC samples with detectable viral reads and measured no viral reads associated with cells belonging to the plasma cells or TYROBP +  clusters ( FIG. 3C ). The whole B cell receptor (BCR) locus was then assembled de novo, and it was found that virus-associated, IgM B cells tended to have less hypermutations than other NM B cells from the same subjects ( FIG. 3D ). In contrast, V/J usage in heavy and light chains was not apparently different between virus-associated and bystander B cells in the same subjects (data not shown) Moreover, expression of a number of genes were found in this study to correlate with intracellular viral abundance in DENV-infected Huh7 cells and are known to participate in intracellular viral dynamics was not altered in the virus-associated B cells, raising the possibility that these cells are associated but not infected with DENV. A slight anticorrelation is in general expected due to dropout effects. Single molecule fluorescence in situ hybridization smFISH) was performed to detect positive and negative strand DENV RNA from naive B cells and monocytes from a healthy blood donor. No evidence was observed of either DENV strand in these B cells, unlike monocytes or control Huh7 cells (data not shown). 
     In addition to counting the DENV reads, the reads were mapped in an iterative manner and ˜300,000 viral reads were recovered from patient 1-026-1 and ˜2,000 reads were recovered from patient 1-036-1. High coverage was obtained across the whole DENV genome and a third of the genome for these patients, respectively. The intrapatient population genomics showed a wide range of conservation levels, as determined by minor allele frequencies ( FIG. 3E  and  FIG. 4A ). Site-specific Shannon entropy restricted to positions with 200 or more virus reads did not correlate with cross-sectional entropy in DENV serotype 3 ( FIG. 3F  and  FIG. 4B ). This suggests that DENV genomic diversity within a single patient follows a distinct fitness landscape from DENV species as a whole, in agreement with previous evidence (as described in Parameswaran P, et al. (2012)  J Virol.  86:8546-8558) and unlike other viruses such as HIV-1 (as described in Zanini F, et al. (2016)  Elife  4: e11282). 
     Hundreds of non DENV-associated B cells (bystanders) were recovered from samples containing DENV-associated cells. Differential gene expression was computed between these bystanders and B cells from healthy controls, and a strong antiviral response via interferon stimulated genes IF16, IFI44L, and IFIT3 was identified ( FIG. 3G ). Moreover, it was considered whether the diversity of the immune repertoire (B and T cell receptors—BCR and TCR) could play a role in virus-cell association. Whereas assembled BCRs from patients with detected DENV-associated B cells scattered into small clones, the BCR repertoire of patients 1-013-1 and 1-020-1, who had no DENV-associated B cells, contained large clonal families (“lineages”) comprised of multiple plasmablasts sharing similar antibody heavy chains, indicating a rapid and large clonal expansion in the B cell compartment ( FIG. 3H ). Clones were called based on only the α/γ chain or only the β/δ chain in preparing the lineages. These large clonal families all contained cells belonging to healthy, dengue, and severe dengue patients, thereby supporting their assignment as public clonotypes. The fact that such plasmablast expansions were captured simply as part of these patients&#39; circulating B cell populations was surprising given the vast diversity of possible BCR rearrangements (see Georgiou G, et al. (2014)  Nat Biotechnol.  32:158-168) and could be indicative of a more extensive plasmablast response and concurrent rise in neutralizing antibody titers known to occur in response to acute dengue infection (see Appanna R, et al. (2016)  EBiomedicine  12:178-188). One clonal family had members belonging to both patients, while another featured two plasmablasts with nearly identical heavy chains, but distinct light chains. This raises the possibility of parallel somatic evolution (see Parameswaran P, et al. (2013)  Cell Host Microbe  13: 691-700). Large public clones in the a and chains, independent of disease status, were identified while β and δ clones were found to be mostly private. Within the T cell compartment, clustering by TCRβ/δ CDR3s produced clonal families that were largely private to an individual, while clustering according to TCRα/γ CDR3s revealed known invariant T cell subsets, including invariant natural killer T cells (iNKT) and mucosal associated invariant T cells (MAIT), as well as public γ chain CDR3 sequences (e.g. ALWEYQELGKKIKV (SEQ ID NO:342)) (data not shown) (see Ravens 5, et al. (2017)  Nat Immunol  18:393-401). 
     Multiple genes, particularly interferon response genes, were upregulated in a cell-specific manner prior to progression to SD. The expression of MX2 in naive B cells and CD163 in CD14 +  CD16 +  monocytes was predictive of SD. The majority of DENV-associated cells in the blood of two patients who progressed to SD were naive IgM B cells expressing the CD69 and CXCR4 receptors and antiviral genes, followed by monocytes. Bystander uninfected B cells also demonstrated immune activation, and plasmablasts from two patients exhibited antibody lineages with convergently hypermutated heavy chain sequences. Lastly, assembly of the DENV genome revealed diversity at unexpected genomic sites. This study presents a multi-faceted molecular elucidation of natural dengue infection in humans and proposes biomarkers for prediction of SD, with implications for profiling any tissue and viral infection, and for the development of a dengue prognostic assay. 
     The heavy and light chain amino acid and nucleic acid sequences of the BCR repertoire of patients 1-013-1 and 1-020-1 ( FIG. 3H ) are set forth above in Table 1 and Table 2. Table 3 and Table 4 further summarize the specific CDR amino acid sequences, the grouped lineages, the isotype, and the V and J types for each of these antibodies. Amino acids that vary between antibodies in a specific lineage are bolded. Table 3 also identifies the median pairwise percent similarity between the CDR3 amino acid sequences of the heavy chain sequences in each lineage. All of these sequences represent exemplary antibodies within the context of this disclosure. Further study of these antibody sequences are described in the subsequent examples. 
     Example 2. Recombinant Antibody Production 
     DNA sequences for the antibodies identified from patients 1-013-1 and 1-020-1 were synthesized as gene fragments (GenScript Biotech Corp.) with at least 15 base pair overlaps matching the 5′ signal sequence and 3′ constant region in human IgG 1 , kappa or lambda expression vectors. Vectors used were in-house constructs of Genbank LT615368.1, deposited by Tiller, T., et al. (2009) J. Immunol, Methods 350(1-2):183-193, Clones were generated based on the VDJ sequences set forth in Table 1 and Table 2. The flanking nucleotide sequence added to each of these nucleotide sequences are set forth below in Table 12. Certain antibody sequences were codon optimized prior to cloning using a  Homo sapiens  DNA codon optimization tool (Integrated DNA Technologies). The codon optimized sequences are set forth below in Table 13 and Table 14. Gibson assembly of the gene fragments was performed to prepare the coding sequences, and the coding sequences were cloned into the vectors. The clones were confirmed by sequencing. The clone DNA was transfected into 96-well blocks of 1 mL suspension 293 cells. Four days post-transfection, supernatants were assayed for antibody expression using an IgG ELISA. 
     Miniprep DNA (0.5 μg) for the MC and LC of each mAb was transfected into a 96-well, round bottom, deep well plate (VWR) containing 1 mL of 1.5×10 6  suspension 293 cells (Expi293 System Kit, ThermoFisher). Cultures were grown in a Multitron shaker (INFORS HT) for four days.

     Example 3. Neutralization Assays 
     Sera was obtained from subjects 013-1 and 020-1 as identified in Example 1. Reporter virus particles (RVPs) generated by complementation of a GFP-expressing sub-genomic West Nile virus (WNV) replicon with the structural genes of Dengue virus serotypes 1-4 (DENV1-4), Zika virus (ZIKV), or WNV were incubated with a 1:240 dilution of heat-inactivated sera for 1 hour at room temperature before addition of Raji cells that stably express DC-SIGN-R. After 2 days of incubation at 37° C., infection was scored as a percentage of GFP-positive cells by flow cytometry. Antibody-mediated neutralization of virus infectivity was measured as the percent reduction of GFP-positive cells in the presence versus absence of antibody. Table 15 below shows the percent neutralization of DENV1-4, ZIKV, and WNV RVPs by serum antibodies from patients 013-1 and 020-1.

     IgG-containing supernatant (range of 3-3709 ng/ml, see Table 14, 4 th  column) obtained following co-transfection of Expi293 cells with 33 out of the 38 paired heavy and light chain sequences from these subjects were tested for virus neutralizing activing as described in the prior paragraph. Neutralization was calculated as the percentage of reduction of infected cells observed in the presence versus absence of antibody. Monoclonal antibody C10(described by Dejnirattisai W., et al. (2015)  Nat Immunol.  16(2):170-177) and monoclonal antibody E16 (described by Oliphant T, et al. (2005)  Nat Med  11(5):522-530) were used as positive controls for neutralization of DENV and WNV, respectively. The data from this experiment is shown in Table 16 below. 
     Monoclonal antibodies with at least 50% neutralizing activity will be scaled up for production, quantified by ELISA, and re-tested in the neutralization assay using ten serial five-fold dilutions (starting at 10 μg/ml). Antibody dose-response neutralization curves will be analyzed by non-linear regression (GraphPad Prism v 6.0g, GraphPad Software Inc.) to calculate the concentration of antibody required to inhibit infection by 50% (IC50). 
     Example 4. ELISA to Quantify IgG in Expi293 Supernatants 
     Plates (96 well, Nunc Maxisorb, VWK) were coated overnight with anti-Human IgG, Fcγ (Jackson Immunoresearch) at 2 μg/ml in PBS, pH7.2. The next day the plate was washed 3×300 μl PBST and blocked for 1 hour in 1% BSA/PBS. A human IgG (Jackson Immunoresearch) standard curve was prepared in 1/3 dilutions starting from 100 ng/mL, in assay diluent (0.5% BSA/PBS/0.05% Tween-20). Supernatants from Expi293 cells expressing the patient antibodies as described in Example 2 were diluted in assay diluent between 1/5 and 1/500. Both standards and samples were allowed to bind for 2 hours, washed 6×300 μl PBST and a 1/5000 cocktail of anti-human kappa-HRP and lambda-HRP antibodies (SouthernBiotech) added for 1 hour in assay diluent. After 6×300 ul PBST washes, the plate was developed with TMB (KPL). The data for this experiment is shown in Table 16 (fourth column from left).

     Example 5. ELISA to Detect Antigen-Specific Antibodies 
     To immobilize RVPs, high-binding 96-well plates (Corning) were coated with 3 of an anti-flavivirus E protein mouse monoclonal antibody 4G2 (Novus Biologicals) in 100 PBS at 4° C. overnight. Plates were washed six times in wash buffer (PBS containing 0.05% Tween 20) followed by incubation with 100 μl blocking buffer (1% BSA in PBS). Next, DENV2 RVPs as described in Example 3 was added in 100 μl blocking buffer. One microgram of DENV2 recombinant E protein (Native Antigen) was immobilized directly on the plate in 100 ul PBS overnight at 4° C.). Plates were then incubated for 1 hour at room temperature and washed six times with wash buffer. Human mAbs from subjects 013-1 or 020-1 as described in Example 2 were diluted in blocking buffer (100 μl; 2 μg/ml) and added to the plates and incubated for 1 hour at room temperature. Positive controls were monoclonal antibody 2B7 (described by Dejnirattisai W., et al. (2015)  Nat Immunol.  16(2):170-177), which binds only to RVP, and mouse monoclonal antibody 3H5-1 (described by Henchal E A, et al. (1982)  Am J Trop Med Hyg  31(4):830-836), which binds to both rE and RVP, WNV-specific mAb CR4354 (described by Kaufmann B, et al. (2010)  Proc Natl Acad Sci USA  107(44):18950-189:5:5) was used as an isotype control antibody. After washing the plates again with wash buffer, 100 μl of HRP-conjugated mouse anti-human IgG (Thermo Scientific) or HRP-conjugated goat anti-mouse IgG (Thermo Scientific) diluted 1:1000 in blocking buffer was added to plates and incubated for 1 hour at room temperature. 1-Step™ Ultra TMB-ELISA substrate (Thermo Scientific) was added to the plates (100 μl/well) and incubated for six minutes at room temperature in the dark. The reaction was stopped by the addition of 100 μl 1N hydrocholoric acid (Fisher), and the optical density at a wavelength of 450 nm was determined (Spectramax i3, Molecular Devices). The data from this experiment is shown in  FIG. 5 . 
     Example 6. Binding Profile of Purified IgGs 
     Production of six antibodies (J9, C4, B10, L8, M1, I7) was scaled up by transfection of 5-50 ml ExpiCHO cells (Invitrogen), followed by IgG purification over a Protein A column (MabSelect SuRe, GE Healthcare). These antibodies were selected based on their ability to neutralize &gt;50% of infection by at least four of the six viruses tested in Table 16. Consistent with the pilot screen using crude IgG-containing supernatant (Example 5,  FIG. 5 ), B10, L8, M1, I7 were found to bind to both DENV2 soluble recombinant E (rE) protein and RVPs, while J9 bound to RVPs only. No binding of C4 was detected to either rE or RVPs, despite performing the ELISA under two different temperature conditions (25° C. or 37° C.). These data are summarized in  FIGS. 6A-6B . 
     Example 7. Neutralization Potency of IgGs 
     Dose-response neutralization assays as described in Example 3 were performed to obtain IC50 values, which represent the antibody concentration at which 50% of virus infection is inhibited. As controls, we included previously described anti-flavivirus broadly neutralizing antibodies EDE1 C10 and EDE2 B7 (described by Dejnirattisai W., et al. (2015)  Nat Immunol.  16(2):170-177) and the WNV-specific mAb CR4354 (described by Kaufmann B, et al. (2010)  Proc Natl Acad Sci USA  107(44):18950-18955). The results are summarized in Table 17. Despite undetectable binding to DENV2 by ELISA ( FIGS. 6A-6B ), antibody C4 neutralized all four serotypes of DENV (DENV1-4), although with low potency against DENV4. J9 displayed the highest potency, neutralizing DENV1-4 with an average IC50 of 23 ng/ml. Although, unlike the EDE1 C10, J9 did not neutralize ZIKV, it inhibited some DENV serotypes with up to approximately 60-fold greater potency.

     Example 8. Impact of Heavy Chain Modification on J9 Neutralizing Activity 
     As shown in Table 13, the modified J9 heavy chain DNA sequence used for recombinant antibody production (SEQ ID NO:332) included a deletion of a glycine residue present in the native amino acid sequence. A new gene fragment that included the native glycine residue in the heavy chain sequence (SEQ ID NO:50) was synthesized for recombinant IgG production with the corresponding light chain using similar methods as those described in Example 2. The IgG encoding the native heavy chain sequence is referred to in the following examples as J9v1. As shown in  FIG. 7 , J9 and J9v1 displayed similar breadth and potency in their neutralizing activity against DENV1-4. The amino acid residue sequences of J9v1. VH (SEQ ID NO:442) and J9 VH (SEQ ID NO:442) are shown below with the deleted Glycine reside underlined.

     Example 9. Neutralization Potency of Fabs 
     To determine whether J9v1 requires bivalent binding for potent neutralization, Fab fragments from IgG (Pierce Fab Preparation Kit, Thermo Scientific) were generated and purified and tested in neutralization assays at 2× molar concentration relative to IgG. Despite a reduction in neutralization potency relative to IgG, J9v1 Fab was still able to neutralize DENV2 completely. In contrast Fab fragments of C4 and EDE1 C10, for which a large proportion of viruses remained infectious at the highest concentration tested (6.7 μg/ml for J9v1, EDE1 C10, EDE2 B7; 20 μg/ml for C4). These results are shown in  FIGS. 8A-8D . 
     Example 10. Potential for Antibody-Dependent Enhancement In Vitro 
     In vitro, sub-neutralizing concentrations of antibodies can facilitate entry into host cells expressing Fc gamma receptor (FcγR). This process, termed antibody-dependent enhancement (ADE), has been implicated in pathogenesis as the risk of severe disease following secondary DENV infection is highest within a range of intermediate concentrations of pre-existing DENV-specific antibodies, beyond which protection. ADE potential of the antibodies was measured in K562 cells, which express FcγR and are poorly permissive for infection in the absence of antibodies, making them a useful system in which to study ADE. The experiment setup is similar to the neutralization assay described in Example 3, except that K562, not Raji-DCSIGNR, cells, were used. For each antibody tested (J9v1, C4, L8, and controls EDE1. C10 and CR4354), the peak enhancement titer was calculated, which is the concentration at which the highest level of ADE of DENV2, ZIKV, or WNV was observed. Consistent with its high neutralization potency. J9v1 displayed the lowest peak enhancement titer (10 ng/ml) against DENV2, beyond which neutralization was observed ( FIG. 9A  and  FIG. 9D ). At high antibody concentrations, C4 and L8, modestly enhanced ZIKV infection ( FIG. 9B  and  FIG. 9E ). L8 also mediated ADE of WNV ( FIG. 9C  and  FIG. 9F ) with no neutralization observed even at the highest antibody concentration tested (10 μg/ml). Thus, despite DENV-specific neutralizing activity, C4 and L8 displayed binding cross-reactivity against other flaviviruses. In contrast, J9v1 did not enhance ZIKV or WNV infection, suggesting an inability to bind these flaviviruses. Overall, these results suggest that the high neutralization potency of J9v1 limits its potential for ADE to a narrow range of low antibody concentrations, beyond which neutralization is observed. 
     Example 11. Effect of Virus Particle Maturation on Neutralizing Activity 
     Although cleavage of prM, a chaperone protein for the envelope (E) glycoproteins from the virus particle surface is a required step in the flavivirus life cycle, infectious particles produced in vitro are often heterogeneous with respect to their prM content. A recent study showed that DENV isolated directly from plasma of acutely infected individuals displayed increased prM cleavage efficiency and were less sensitive to neutralization than DE′ passaged in cell lines (Raut, R. et al., 2019, Proc. Natl. Acad. Sci USA 116(1):227-232), suggesting that the ability to neutralize mature DENV particles lacking prM is important for antibody-mediated protection against circulating viruses. 
     The ability of J9v1, C4, and control antibodies EDE1 C10 and mouse monoclonal antibody E60 (Oliphant, T. et al., 2006, J. Virol. 80(24):12149-59) to neutralize DENV2 produced using standard methods (prM+) or in the presence of overexpressed human furin (prM−), which increases prM cleavage efficiency, was compared. As previously shown, E60 did not efficiently neutralize prM− DENV2 ( FIG. 10D  and  FIG. 10E ), Similarly, increased prM cleavage efficiency reduced C4 neutralization potency ( FIG. 10B  and  FIG. 10E ), resulting in a large proportion of viruses that remained infectious at the highest concentration tested (10 μg/ml). In contrast, virion maturation state had minimal effects on the neutralization potency of J9v1 ( FIG. 10A  and  FIG. 10E ) and EDE1 C10 ( FIG. 10C  and  FIG. 10E ). 
     Example 12. Mechanism of Neutralization 
     It was investigated whether J9v1 and C4 could inhibit infectivity after virus attachment to cells, which is a characteristic of many potently neutralizing antibodies against flaviviruses. Neutralization assays as described in Example 3 were performed with a few modifications. Specifically, antibodies were incubated with virus either before (pre-) or after (post-) the addition of Raji-DCSIGNR cells at 4° C. Following wash steps in cold media to remove unbound virus, cells were incubated for 48 h at 37° C. and infection measured by flow cytometry as described in Example 3. 
     As observed with the control mouse mAb m3H5-1 (Henchal, E. A., et al., 1982, Amer. J. Trop. Med. Hyg. 31(4):830-836), when added after virus attachment to cells, C4 failed to inhibit 40-50% of infection at the highest concentration tested (300 μg/mL) ( FIG. 11B  and  FIG. 11D ). In contrast, J9v1 ( FIG. 11A ) and EDE1 C10 ( FIG. 11C ) potently neutralized DENV2 infection in both pre- and post-attachment neutralization assays. 
     Example 13. Lineage Analysis of J9 Clonal Family 
     To gain insight into the in vivo development of the bNAb J9 and J8 clones, PBMCs from sample 1-013-02 (the next sample timepoint of the donor from which J9 and J8 mAbs were identified in plasmablasts) were used to perform next generation sequencing of the B cell receptor (BCR) repertoire. The PBMCs were also polyclonally stimulated to increase the percentage of antigen specific sequences (Waltari et al., 2019, Frontiers in Immunology, Vol. 10, June 25, Article 1452) and both analyses were focused on the heavy chain repertoires, which are sufficient to identify clonal relationships (Zhou &amp; Kleinstein, 2019, bioRxiv, doi.org/10.1101/665760; pre-preint of article; available online Jun. 18, 2019), 
     A. Materials and Methods 
     Preparation of Growth-Arrested Feeder Cells, Human fibroblast cell line MRC-5 (CCL-171) was obtained from ATCC (Manassas, Va.) and grown in B cell growth media containing Corning® DMEM [+] 4.5 g/L glucose, sodium pyruvate [−] L-glutamine (VWR International, Radnor, Pa.), 1×Pen/Strep/Glu and 10% ultralow IgG HI-FBS (Thermo Fisher Scientific, Waltham, Mass.), to 80% confluence before being treated for 4 h with 5 μg/ml mitomycin C (Tocris, R&amp;D Systems). Monolayers of growth arrested cells were washed 3 times with PBS, harvested with trypsin, neutralized with growth media, washed 1× in growth media and finally cryopreserved using 10% DMSO, 30% HI-FBS in growth media. 
     Preparation of PBMCs for BCR Repertoire Analysis. The day before PBMCs were thawed, 1.2×10 6  feeder cells were seeded in a T25 flask (VWR) in 4 ml of B cell growth media and cultured overnight in a humidified 37° C. 5% CO 2  incubator. PBMCs were quickly thawed at 37° C., washed 1× in 10 ml of growth media, and divided in half. One half was resuspended in 4 ml of 2×B cell growth media containing 2×ITS from 100× Insulin, Transferrin, Selenium (Thermo Fisher Scientific), 20 ng/ml 2 ng/ml IL-2. King/ml 10 ng/ml IL-6 (R&amp;D Systems, Minneapolis, Minn.) and 4 μg/ml CpG (ODN 2006-G5, InvivoGen, San Diego, Calif.). The 4 ml of PBMCs were then added to the T25 flask with 4 ml of conditioned feeder cell media. The final 8 ml cell culture was allowed to grow for 5 days at 37° C., 5% CO 2  in a humidified incubator. At day 5 the cells were pelleted at 350×g for 5 min, resuspended and lysed in Qiagen RLT buffer with beta-mercaptoethanol for 10 min, frozen on dry ice, and transferred to −80° C. storage until RNA purification. The second half of PBMCs were immediately lysed in RLT buffer without further processing. 
     BCR Primer Design and Pool Preparation. Dry oligos of desalted purity (IDT) were reconstituted at 100 μM in Qiagen EB and stored in aliquots at −80° C. The oligos are shown in Table 18 and contain sufficient random base pairs to act as unique molecular identifiers (UMIs) for every mRNA transcript present in a sample. LAM are added in variations of 8 or 12 nucleotide stretches to offset the high level of sequence similarity and lower Illumina sequencing accuracy in Ig amplicons at the 3′ and 5′ ends (see table footnotes). A pool of IgH RT primers was made by mixing 10 μl of each primer from the individual 100 μM stocks (100 μl final volume). Separately 10 μl of each of lambda RT primers were mixed from individual 100 μM stocks (20 μl final volume). Next, a 10 μM, 5:1 molar mix of Ig heavy:lambda chain RT primers was made using 16.7 μl RT primer pool and 3.3 μl lambda RT primer pool, in a final 180 μl of Qiagen EB. The same procedure and molar ratio were repeated in the preparation of the IgH (n=12): lambda (n=16) forward primers. Kappa RT and forward primer pools were prepared by mixing 10 μl of each kappa RT (n=2) primer or kappa forward (n=8) primer from the individual 100 μM stocks and then diluting the mix to 10 μM final.

                   1 The 5′ end of the primers correspond to adapter sequences for PE indexing, the middle 8 or 12 Ns for random barcode UMIs (unique molecular identifiers), followed by gene-specific sequences (constant domain reverse or framework 1 region forward). Primer design was based on primers used in Vollmers et al. 2013, Proc. Natl Acad. Sci. USA 110 (33) 13463-13468 and Waltari et al. 2019. At each N position, oligos were synthesized using a 25/25/25/25 mix of each nucleotide.

     BCR Amplicon Preparation. Total RNA yields from the PBMC and stimulated PBMCs were determined by absorbance at 260 nm on the NanoDrop™ One (Thermo Fisher Scientific). An input of 100 ng total RNA was used for first strand cDNA synthesis with gene-specific reverse transcription (RT) primers directed to the constant regions. The RT primers for IgG, IgM, IgA and lambda were pooled, whereas the kappa RT was done in a separate reaction. Light chain kappa RT was carried out in separate reactions because the transcript abundance and amplification efficiency tended to out-compete heavy and lambda chains in multiplexed reactions. Primers are shown in Table 18. One hundred nanograms total RNA was added on ice to 10 μM of pooled RI primers for HC/lambda or kappa chain (primer pools as described above and in Table 18) and 1 mM of dNTP in a 10 μl final volume, allowed to anneal for 3 min at 72° C., and returned to ice. First strand reverse transcription was performed using SuperScript III RT (200 U/μl, Thermo Fisher Scientific). To the 10 μl annealed sample, on ice, 4 μl of 5× Superscript RT buffer, 1 μl 0.1M dithiothreitol, 1 μl Superase-IN (20 U/μl, Thermo Fisher), and of RNase free water were added, to give a final volume of 20 μl. cDNA was made in a thermocycler for 1 hour at 50° C., 5 min 85° C., 4° C. hold, Second-strand cDNA was synthesized using Phusion High Fidelity Polymerase (Thermo Fisher). To the 20 μl first strand cDNA, 10 μl of 5× Phusion buffer, 1 μl of 10 mM dNTPs, 0.5 μl Phusion Tag, 1.5 μl DMSO, 7 μl of RNase free water, and 10 μl of the 10 μM pool of forward primers (as described above and shown in Table 18), were added, to give a final volume of 50 μl. Samples were incubated at 98° C. for 4 min, 52° C. for 1 min, 72° C. for 5 min and 4° C. hold. Double-stranded cDNA was transferred to a low retention DNase-free 1.5 ml Eppendorf tube and purified two times using Agencourt® AMPure® XP beads (Beckman Coulter, Brea, Calif.), at a volume ratio of 1:1, and eluted in 25 μl of Qiagen EB buffer. Double-stranded cDNA was PCR amplified with Platinum DNA Polymerase High Fidelity (5 U/μl HiFi Taq, Thermo Fisher). To the 25 μl of eluted second strand cDNA, 5 μl of 10×HiFi Taq buffer, 2 μl of 50 mM MgSO4, 1 μl 10 mM dNTPs, 0.2 HiFi Taq, 1 μl each of two PE primers completing Illumina adapter sequences (Table 18) and 14.8 μl of water, were added, to give a final volume of 50 μl. Samples were run at 94° C. for 2 min, 27 cycles of 94° C. for 30 sec, 65° C. for 30 sec, and 68° C. for 2 min, followed by 68° C. for 7 min and 4° C. hold. Final libraries were run on 2% E-Gel™ EX agarose gels (Thermo Fisher Scientific) and bands extracted with Quantum Prep Freeze N′ Squeeze™ DNA Extraction Spin Columns (BioRad, Hercules, Calif.). After one clean-up with 1:1 Agencourt® AMPure® XP beads, amplicons were eluted in 25-35 μl Qiagen EB. An aliquot was diluted to 5-500 μg/μl and 2 μl quantified on the Agilent Fragment Analyzer Automated CE System using the DNT-474 High Sensitivity, 1 bp-6000 bp, NGS Fragment Analysis Kit (Advanced Analytical Technologies, Agilent Technologies, Santa Clara, Calif.), according to the manufacturer&#39;s instructions. Pairs of samples (PBMC and stimulated PBMC amplicons) were sequenced together using different Illumina barcodes to demultiplex after sequencing, Amplicon mixtures corresponding to 10:1 ratios of heavy chain+lambda:kappa were submitted for 300 forward×250 reverse sequencing with MiSeq v3 kits (Illumina) at the Chan Zuckerberg Biohub Genomics Center, Addition of 15-20% v/v PhiX Control Library was added to increase sequence diversity and overall sequencing performance. Each MiSeq run resulted in 7.5-20 million paired raw reads, which was reduced to 0.5-3.5 million unique Ig sequences after processing. All MiSeq data was deposited in the NCBI Sequence Read Archive (SRA) database under accession PRJNA524904. 
     BCR Repertoire Data Analysis Pipeline, After completion of MiSeq sequencing, antibody repertoires were analyzed using methods based on the Immcantation pipeline. An overview of BCR sequencing analysis and practical considerations included in the Immcantation pipeline, are reviewed in Yaari, G. and Kleinstein, S. H., 2015, Genome Medicine, Vo. 7, Article 121 (doi: 10.1186/s13073-015-0243-2). This pipeline, available at immcantation.readthedocs.io, continues to be updated as the field advances, and is composed of multiple software packages: pRESTO, Change-O, SHazaM, TIgGER, and Alakazam. Because the Immcantation pipeline can be run using Docker containers, a cloud-based workflow was created incorporating Reflow (available at github.com/grailbio/reflow) that allowed for seamless processing of the constituent Immcantation software packages. The workflow is available at Github (github.com/czbiohub/bcell_pipeline). Some key characteristics of this new workflow include the use of unique molecular identifiers (UMIs) at both 5′ and 3′ ends of the Ig sequences, the collapse of sequences with identical UMIs, the use of the IgBLAST algorithm (Ye, J. et al., 2013 , Nucleic Acids Research  41 (Web Server Issue):W34-W40, pub. online May 11, 2013) to calculate general Ig characteristics of each sequence, and the determination of clonal families by first calculating a clonal threshold nucleotide distance via a nearest-neighbor algorithm and then collapsing sequences based on this threshold (Gupta, N. T. et al., 2017, J. Immunology 198(6):2489-2499). We ran the initial steps using the pRESTO script (presto-abseq.sh at bitbucket.org/kleinstein/immcantation/src/97a70949607b6671a182a84d5052b705d1677891/pipe lines/?at=default) with variations that are included in the Github repository for this work. Given that sample and amplicon preparation included UMIs of varying lengths at both 5′ and 3′ ends to improve sequencing quality, code to standardize the UNIT length for subsequent steps (8 bp at each end) was included. The script first removes reads with average Q scores less than 20, and then annotates the reads based on 5′ or 3′ amplicon primers. All reads with identical UMIs are then collapsed, with consensus sequences created and UMI numbers annotated into the sequence name. This is followed by assembly of 5′ and 3′ paired-ends, at which point the UMIs at both ends are combined to create a 16 bp signature per cDNA transcript, also annotated into the sequence name. In the next step, the constant regions are re-analyzed for each paired read, and isotype and subtype annotated into the sequence name. The final pRESTO steps include collapsing of identical BCR sequences of the same isotype followed by filtering to only include BCR sequences that were found in 2 or more representative reads per UMI, to avoid including sequences that vary only due to sequencing error. The workflow continues with subsequent Immcantation packages, using the following scripts without changes at the website above: Change-0 IgBLAST (changed-igblast.sh), which calculates Ig repertoire characteristics, TigGER (tigger-genotype.R), which estimates novel V-gene alleles, SHazaM (shazam-threshold.R), which determines the optimal threshold for delineating clonal families, and Change-O Clone (changeo-clone.sh) that groups the sequences into clonal families. Lastly, a series of R scripts based on Alakazam were used to visualize results (scripts available at the Github page for this work). This workflow includes both heavy and light chain reads, and all outputs include both sequences, but without knowledge of pairing. As such, analysis was focused only on the more diverse heavy chain results. In addition to the Immcantation procedure of optimizing the clonal threshold value during each analysis (using SHazaM), a second strategy to identify mAb matches to clonal families in the repertoire was used. For these comparisons, all unique heavy chain sequences (i.e. not only those with 2 or more UMIs) were included, the mAb sequences appended, and a constant 12% threshold value in Change-0 was applied to delineate clonal families. 
     B. Results 
     In the repertoire of sample 1-013-02, a total of 43,758 BCR sequences related to the variable heavy chain (VH) of J9 and J8 were identified. Nine and fourteen clones with a 100% match at the nucleotide level to J9 and J8 in the stimulated PBMC repertoire were identified, respectively. A parsimony-based network construction of the heavy chain sequences clonally related to J8 &amp; J9 VH at the nucleotide level is shown in  FIG. 12A . Sequences were limited to 118 that met 3 criteria: 1) highest numbers of unique molecular identifier (UMI) counts (&gt;35 in PBMC repertoire and &gt;150 in stimulated PBMC repertoire IgG sequences and &gt;15 in IgA sequences), 2) &lt;5% somatic hypermutation, and 3) 97% identity to J9 or J8 sequences. The J9 and J8 lineage derived from a founder clone using a VDJ recombination of IGHV1-69 with IGHD2-2 and MEW with no CDRH3 insertions or deletions. The majority of clones were of the IgG 1  subtype, with no IgM identified having a UMI count &gt;2 and only a small percentage of IgA (1.8% of stimulated PBMC relatives;  FIG. 12A , squares). The numbers along lines of the lineage represent the nucleotide changes from the founding IGVH1-69*05 germline. Sequences obtained from the PBMC repertoire are shown in the lightest gray and the greater number obtained from the antigen-enriched stimulated PBMC repertoire, are shown in gray. Sequences found in both sample conditions are shown in dark gray. The relative size of the circles correlates to the number of reads for the sequence, which in turn is thought to correlate to the number of B cells present in the sample, with larger circles representing more abundant clones. These abundant clones, the founder clone and a consensus sequence derived from the 43,758 clonotypes are listed by nucleotide and amino acid sequence in Tables 19A-19B. Regarding Table 19A, forward primers used for NGS do not cover the first 24 nucleotides (8 amino acids) in VH framework 1. Many positions indicate a selection pressure preference for a particular size, charge, or hydrophobicity as shown in Table 20. The framework 2 glycine insertion of J9v1 was removed in a recombinant mAb variant (J9) and shown to not be necessary for function as shown in Example 8. Variant VII sequences would preferably retain the identity of the invariable amino acid residues identified in Table 20 so as to reduce likelihood of impact on function. 
     Overall, the repertoire showed a rapid expansion of class switched IgG 1  with numerous point nucleotide (nt) mutations from germline, strongly suggesting both J9 (28 nt) and J8 (27 nt) plasmablasts derived from memory B cells from a prior infection. Less mutated IgG clones A (3 nt), B (5 nt), and C (5 nt) close to the top of the tree of the acute phase repertoire could represent antibodies derived from a de novo immune response, or from less mutated memory clones. Several VH mutations occur towards the top of the lineage tree including CDR-H2 I53F, CDR-H3 T99A/P and D100cH ( FIG. 12A , clones labeled A, B and C), and are retained throughout the continued somatic hypermutation (SH v1) of the VH, and therefore may be required for activity. An amino acid alignment of the founder, J9 and J8 VH sequences is shown in  FIG. 12B  (full sequences listed in Table 21A; founder CDR sequences listed in Table 21B), The three residues that are predicted to be key for improving or initiating the founder clone&#39;s binding to DENV are in bold. The numbering used in Table 20 and  FIG. 12B  follows the Kabat system (Kabat E. A. et al, 1991 , Sequences of Proteins Immunological Interest , Fifth Edition. NIH Publication No. 91-3242) and the CDRs are defined using a combination of residues defined by Chothia C. and Lesk M., 1987, J Mol Biol. 196: 901-917 and Kabat (1991).

     Clonotypes conforming to the J8/J9 lineage derived from deep sequencing 1-013-02 PBMC were also found in the same donor&#39;s convalescent PBMC sample (1-013-03; 227 sequences) and a second donor&#39;s acute and convalescent PBMC samples (1-(20-02 and 1-020-03; 36 and 3 sequences, respectively) from the same cohort of Colombian DENV patients. In addition, 82 clonotypes of J8 and J9 were identified by in silico analysis of sequences from a different cohort DENV patients from Nicaragua (subjects 289, 311, 320, 517 and 524) deposited in the Observed Antibody Space resource (antibodymap.org) by Parameswara P. et al. (Convergent antibody signatures in human dengue.  Cell Host Microbe  13(6): 691-700). These sequences are expressly excluded from the embodiments described in this disclosure. The J9/J8 clonotypes were members of hundreds of thousands of VII sequences from the Nicaraguan cohort deposited but were not identified as convergent among subjects. 
     The light chains of both J9 and J8 used the same founder germline IGKV3-11 and IGKJ2 genes with identical CDR lengths (but include different 6nt insertions in CDRL3), and SHM (10 nt and 3nt, respectively) with only one mutation in common (CDRL2 position T56S). Immunoglobulin heavy and light chains assemble into a single BCR protein for binding and selection by antigen, therefore the LC sequences are expected to contribute uniquely to the activities of the J8 and J9 mAbs. However, as the NGS data does not include VH/VL pairing, relationships between the sequenced VII and VL repertoires cannot be assigned. It is expected that the VII founder sequence and the J8 and J9 VH sequences will function with LC other than those identified in the studies described in this disclosure. From the BCR repertoire analysis, the number of VL sequences are more than 100-fold fewer than HC sequences using 0.18/9 LC/HC sequence constraints. 
     Example 14. Broadly Neutralizing Antibodies from Divergent Lineages 
     Although no neutralizing activity was detected for J8 in the initial screen with crude IgG-containing supernatant (see Table 16), the lineage analysis described in Example 13 revealed that this antibody belonged to a clonally expanded family of extensively matured antibodies, suggesting antigen-selection. Therefore, J8 IgG was expressed and purified and re-tested in neutralization assays along with J9v1 and EDE1 C10 as controls. As shown in  FIG. 13 , J8 displayed similarly broad and potent neutralizing activity against DENV1-4 as J9v1, indicating that multiple maturation pathways within this lineage led to broadly neutralizing antibodies. Indeed, chimeric IgG expressing J9v1 heavy chain with J8 light chain and vice versa displayed similar neutralizing activity against DENV1 and DENV2. However, chimeric IgG expressing J9v1 heavy chain with J8 light chain displayed less potent neutralization of DENV 3 and DENV4, suggesting that the light chain contributed to the neutralizing activity of J9v1 against these viruses.
