Also provided are novel purified and isolated polynucleotides encoding the variant gD molecules. HSV gD-1 and gD-2 region IV variants or fragments thereof are specifically contemplated by the invention. The presently preferred variant molecule gD-1( DELTA 290-299t) is the product of recombinant expression in Sf9 cells of a fusion protein including the signal peptide of honeybee melittin and Patton strain HSV-1 gD wherein (1) the Patton strain amino acid residues 290 through 299 of the mature gD-1 protein have been replaced with the amino acid residues arginine, lysine, isoleucine and phenylalanine, and (2) Patton strain amino acid residues 308 through 369 have been replaced with five histidine residues.

Administration of gD variant molecules of the invention to mammalian subjects, especially humans, for the purpose of preventing HSV infection and/or ameliorating pathological sequelae of HSV infection is specifically contemplated.

Description: HERPES SIMPLEX VIRUS GLYCOPROTEIN D VARIANTS Field of the Invention The present invention relates generally to novel herpes simplex virus glycoprotein D molecules. More particularly, the present invention relates to variant glycoprotein D molecules which are capable of blocking infection of cells by herpes simplex virus. Background of the Invention Herpes simplex viruses (HSV) are human pathogens which cause a variety of disease states including cold sores, eye and genital infections, life- threatening neonatal infections, and encephalitis. HSV is also capable of establishing latent infections in ganglia. The strains designated HSV-1 (oral) and HSV-2 (genital) are members of the family Herpesviridae and are classified in the subfamily alphaherpesvirinae and the genus simplex virus. The viruses have an enveloped double-stranded DNA genome of 150 kilobases (kb) including at least seventy-two open reading frames which encode at least eleven giycoproteins. The genomes of HSV-1 and HSV-2 exhibit extensive homology in regions which are known to encode proteins responsible for antigenic specificity and/or biological activity. Upon infection, several viral giycoproteins act singly or in concert to bind HSV to a susceptible cell and trigger direct fusion between the virion envelope and the cell membrane. Glycoprotein D (gD) of HSV is a component of the virion envelope which plays an essential role in HSV entry into susceptible mammalian cells. The evidence to date suggests that gD binds to a cellular molecule following the initial interaction of HSV giycoproteins gC and gB with heparan sulfate proteoglycans. The interaction between gD and its receptor may stabilize the virus- cell complex prior to membrane fusion which is mediated by other essential giycoproteins such as gB, gH, and gL. See Sisk et al, J. Virol., 68(3): 766-775 (1994) and Tal-Singer et al. , J. Virol. , 69(1): 4471-4483 (1995). The nucleotide sequence of the Patton strain of HSV-1 gD (gD-1) (SEQ ID NO: 3) was first reported in Watson et al. , Science, 218: 381-384 (1982). The strain 333 HSV-2 gD (gD-2) was described in Muggeridge et al. , J. Virol. , 64(S): 3617-3626 (1990). The nucleotide sequence of the strain 333 gD-2 gene is set out in SEQ ID NO: 14 herein. The HSV giycoproteins have been the subject of intense research in development of vaccines useful in preventing or treating HSV infections. See especially, U.S. Patent Nos. 4,709,011 issued November 24, 1987; 4,762,708 issued August 9, 1988; and 5,149,660 issued September 22, 1992; all to co-inventors herein. In addition, significant effort has been expended in the development of anti- viral agents such as nucleoside analogues and interf erons. Nucleoside analogues idoxuridine, trifluridine, vidarabine and acyclovir interfere with HSV genome replication. Interferons interfere with the translation of viral proteins. While some clinical benefit in ameliorating the sequelae of HSV infection has been achieved by treatment with nucleoside analogues and interferons, therapy with both types of compounds can involve significant side effects. See Fields and Knipe, Eds., Fundamental Virology, Chapter 16, Raven Press, New York, New York (1986). Patients treated with acyclovir, for example, may exhibit local inflammation at sites where the drug is administered, renal dysfunction, and encephalopathic changes. Moreover, HSV mutants resistant to acyclovir have been observed and suppression of recurrences ceases when acyclovir is discontinued [Straus et al. , N. Eng. J. Med. , 310: 1545-1550 (1984)] . Experience in the use of vidarabine has revealed neurologic toxicity. Patients treated with interferon may exhibit fever, fatigue, anorexia, weight loss, nausea and vomiting, bone marrow suppression, pain at injection sites, lymphadenopathy, and mild hair loss. Fibroblast interferon has also been reported to induce the formation of anti-interferon antibodies. There thus exists a need in the art for additional products useful in preventing or treating HSV infection. Summarv of the Invention The present invention provides variant HSV gD molecules capable of preventing infection of cells by HSV-1 and/or HSV-2. Also provided are novel purified and isolated polynucleotides (i.e. , DNA and RNA both sense and antisense strands) encoding the variant gD molecules. HSV gD-1 and gD-2 region IV variants or fragments thereof are specifically contemplated by the invention. Generally described, variant gD-1 and gD-2 molecules of the invention are subject to variation and amino acid sequence modification in "region IV" amino acid residues comprising amino acids 277 through 310 of the native Patton strain gD- 1 sequence which are conserved, for example, as residues 276 through 309 of strain 333 gD-2. Modifications preferably include deletions of one or more amino acids at region IV amino acids 290-300 of gD-1 (residues 289 through 299 of gD-2) and most preferably the deletion of, e.g. , gD-1 amino acids 290-299. One or more amino acid residues not normally present in region IV may replace one or more region IV residues deleted. It is also preferred that "transmembrane" region amino acid sequences ordinarily present in native gD-1 and gD-2 proteins be deleted, for example, by deletion of carboxy terminal residues 306-369 of gD-1 (305 through 368 of gD-2). The above-noted modifications do not operate to delete any of the native potential N-linked glycosylation sites of gD-1 and gD-2 polypeptides, so that recombinant expression of the molecules in host cells capable of glycosylation will ordinarily be expected to result in formation of glycoprotein products. Variant gD-1 and gD-2 proteins and giycoproteins of the invention, when produced by recombinant methods, may include additional amino acid residues as artifacts of the expression system employed (e.g. , residues remaining after signal sequence processing of fusion proteins) or as a result of modification for purposes of facilitating protein/glycoprotein isolation (e.g. , a polyhistidine carboxy terminal sequence). The presently preferred gD-1 variant molecule, designated gD-l(Δ290- 299t), is the product of recombinant expression in Sf9 cells of a fusion protein including the signal peptide of honeybee melittin [Tessier et a , Gene, 98: 177-183 (1991)] and Patton strain HSV-1 gD wherein (1) the Patton strain amino acid residues 290 through 299 of the mature gD-1 protein have been replaced with the amino acid residues arginine, lysine, isoleucine and phenylalanine, and (2) Patton strain amino acid residues 308 through 369 have been replaced with five histidine residues. When expressed in Sf9 cells, cleavage of the melittin signal peptide results in the presence of aspartate and proline residues at the amino terminus of the variant molecule. The amino acid sequence of gD-l(Δ290-299t) is set out in SEQ ID NO: 2 and the preferred DNA sequence encoding gD-l(Δ290-299t) is set out in SEQ ID NO: 1. Also provided are full-length gD variants in which step (1) above is performed, but step (2) is not. The amino acid sequence of such a variant, designated gD-l(Δ290-299) is set out in SEQ ID NO: 11 and the preferred DNA sequence encoding gD-l(Δ290-299) is set out in SEQ ID NO: 10. Autonomously replicating recombinant constructions such as plasmid and viral DNA vectors incorporating sequences encoding variant gD molecules and especially vectors wherein DNA encoding variant gD molecules is operatively linked to an endogenous or exogenous expression control DNA sequence and a transcription terminator are also provided. According to another aspect of the invention, procaryotic or eucaryotic host cells are stably transformed with DNA sequences of the invention in a manner allowing the desired variant gD molecule or fragment thereof to be expressed therein. Host cells expressing variant gD molecules can serve a variety of useful purposes. Such cells constitute a valuable source of immunogen for the development of antibody substances specifically immunoreactive with the gD variants. Host cells of the invention are conspicuously useful in methods for the large scale production of variant gD molecules or fragments thereof wherein the cells are grown in a suitable culture medium and the desired polypeptide products are isolated from the cells or from the medium in which the cells are grown by, for example, immunoaffinity purification or purification on nickel affinity columns. HSV variant gD molecules may be chemically synthesized, but are preferably produced by recombinant procedures involving procaryotic or eucaryotic host cells of the invention. The use of insect (e.g. , Sf9 cells) or mammalian host cells is expected to provide for such post-translational modifications (e.g. , myristolation, glycosylation, truncation, lipidation and tyrosine, serine or threonine phosphorylation) as may be needed to confer optimal biological activity on recombinant expression products of the invention. Recombinant expression products of the invention may also be chemically modified, for example, modification by attachment of polyethylene glycol groups for the purpose of prolonging the half-life of the products upon intravenous administration. Also comprehended by the present invention are antibody substances (e.g. , monoclonal and polyclonal antibodies, single chain antibodies, chimeric murine variable region/human constant region antibodies, CDR-grafted antibodies and the like) and other binding proteins specific for the variant gD molecules. Anti-idiotypic antibodies specific for the variant gD molecule-specific antibody substances are also contemplated. Antibody substances of the invention are conspicuously useful in purifying or detecting variant molecules of the invention. Administration of gD variant molecules or fragments thereof to mammalian subjects, especially humans, for the purpose of preventing HSV infection and/or ameliorating pathological sequelae of HSV infection is specifically contemplated. Various animal models for HSV infection are accepted in the art and include, but are not limited to, the rabbit and mouse eye models of herpes keratitis [Hill et al., Curr. Eye Res. , 6: 1065-1071 (1987) and Rock and Fraser, Nature, 302: 523-525 (1983)], cutaneous herpes infection of hairless (nude) mice [Metcalf et al., Infect. Immunol., 26: 1164-1171 (1979)], vaginal lesions in the guinea pig and mouse [Stanberry et ah, J. Infect. Dis., 146: 397-404 (1982)], foot pad model in mice [Stevens and Cook, Science, 173: 843-845 (1971)], zosterform skin model in mice [Hill et al., J. Gen. Virol. , 39: 21-28 (1982)], and experimental herpes simplex encephalitis induced by intracerebral viral inoculation in mice [Tenser, J. Infect. Dis. , 147: 956 (1983)]. For review, see Stevens, Microbiol. Rev., 53: 318-332 (1989) and Stanberry, Current Topics in Microbiol. and Immunol., 179: 15-30 (1992). The gD variant molecules are administered to the mammal in an amount sufficient to block infection of susceptible cells by HSV. Administration may be by intravenous, intramuscular, subcutaneous, oral, suppository, mucosal, or topical routes. Also contemplated is DNA immunization wherein DNA encoding a gD variant molecule of the invention is provided to a mammal. Compositions of the invention, when administered intravenously, intramuscularly, or orally, are administered in quantities so that variant gD molecules are provided at unit doses effective at inhibiting viral infectivity, for example, unit doses of from 0.01 micrograms to 100 milligrams of gD variant molecule per kilogram of the recipient mammal's body weight. If administered orally or topically, compositions of the invention will include from about 0.0001 % to 20% variant gD molecule. Compositions of the invention also include therapeutically acceptable carriers (e.g. , diluents and/or adjuvants). For general dosage and formulation considerations see Remington: The Science and Practice of Pharmacy, 19th ed. , Mack Publishing Co., Easton, PA (1995). It is also contemplated that the HSV gD variant molecules may act as immunogens in a mammalian recipient when administered by systemic or mucosal routes. Immunization of animals with wild type gD stimulates the production of virus neutralizing antibodies and protects them from lethal challenge with HSV-1 and HSV-2 [Long et al., Infect. Immunol., 37: 761-764 (1984)]. The contemplated dual nature of the gD variant molecules is an advantage of the invention not shared by prior anti-HSV compounds discussed herein.

Detailed Description of the Invention Numerous variant HSV-1 molecules were constructed and analyzed for the ability to rescue infectivity of the gD-null virus F-gD/3 [Ligas and Johnson, J. Virol , 62: 1486-1494 (1988)]. Variant molecules with mutations in one of four regions of gD (region I comprising amino acid residues 27 through 43, region II comprising amino acid residues 126 through 161, region III comprising amino acid residues 225 through 246, and region IV comprising amino acid residues 277 through 310) were unable to effect rescue. The four regions of gD-1 were thus determined to be necessary for entry of HSV into susceptible cells. Further analysis of representative variant molecules, each including mutations in one of the regions, identified a region IV gD variant molecule with particularly potent anti-viral activity. The following examples illustrate the invention wherein Example 1 describes the construction of vectors encoding variant gD-1 molecules of the invention, Example 2 describes recombinant expression of the variants in mammalian and insect cells, Example 3 presents results of analyses of the conformation of the variants and the ability of the variants to complement the null virus F-gD/3, and Example 4 presents results of analyses of the ability of the variants to bind HSV susceptible cells and to block infection of HSV-susceptible cells by HSV-1 strains. Example 5 describes assays demonstrating the ability of variants of the invention to block infection by various other HSV-1 strains while Example 6 describes assays demonstrating that variants block infection of susceptible cells by HSV-2. Example 7 demonstrates the ability of variants of the invention to induce production of HSV neutralizing antibodies when the variants are utilized as immunogens. Example 8 describes methods for producing monoclonal antibodies specifically immunoreactive with variants of the invention. Example 1 HSV gD-1 variants were constructed by linker-insertion mutagenesis essentially as described in Chiang et al, J. Virol , 68(4): 2529-2543 (1994) which is incorporated by reference herein. A gene encoding the region IV HSV gD-1 variant gD-l(Δ290-299t) was constructed from the wild-type gD-1 gene as follows. First, a plasmid pHC236 containing a 12-base Bglll linker inserted at amino acid 290 of gD-1, was generated by oligonucleotide-directed mutagenesis [Kunkel et al, Methods Enzymol, 154: 367-382 (1988)]. The Hindlll fragment containing the entire coding region of gD-1 was excised from plasmid pWW78 described in Muggeridge et al, supra, and then subcloned into the Hindlll site of M13 mpl 8. The sequence of the Patton strain wild type gD-1 coding region present in the Hindlll fragment is set out in SEQ ID NO: 3. A 37 base mutagenic oligonucleotide primer, 5' AGTTTGGTGGGAGGAAGATCTTCCTTTGCGGCGCCAC 3* (SEQ ID NO: 5) which corresponds to nucleotides 1171 to 1196 of SEQ ID NO: 3 and which contained a 12 bp Bglll linker (underlined), was used to synthesize the replicative form (RF) of M13 mpl8. The mutated gD-1 gene was then excised from RF DNA and inserted into the expression vector pRS Vnt EPA (Chiang et al. , supra) which contains the long terminal repeat of Rous sarcoma virus as a promoter and the SV40 early polyadenylation signal. The resulting construct designated pH236 encodes full- length gD-1 with the amino acid arginine replacing isoleucine at residue 290 and the amino acids lysine, isoleucine, phenylalanine, and leucine inserted after the arginine residue. Second, a plasmid pHC237 containing a 12-base Bglll linker inserted at amino acid 300 of gD-1 was constructed by a three-step PCR procedure. The 5' segment of the gD-1 gene was synthesized using a gD-1 upstream primer, 5' CCCAAGCTTATCCTTAAGGTCTCTTT 3' (SEQ ID NO: 6) which corresponds to nucleotides 206 to 223 of SEQ ID NO: 3 and which contains the recognition sequence for the restriction enzyme Hindlll (underlined) to facilitate subsequent insertion into expression vector pRSVnt EPA, and an anti-sense strand primer, 5' TCGCGGCGTCCTGGAAGATCTTCCGGATCGACGGGAT 3' (SEQ ID NO: 7) which corresponds to nucleotides 1201 to 1225 of SEQ ID NO: 3 and which contains the -Sgflll linker (underlined). The primers were used to amplify gD-1 sequences from plasmid pRE4 [Cohen et al , J. Virol , 62: 1932-1940 (1988)]. The 3' segment of the gene was synthesized using a sense primer, 5' GAAGATCTTCCGAGAACCAGCGCACCGTC 3' (SEQ ID NO: 8) which corresponds to nucleotides 991 to 1008 of SEQ ID NO: 3, and a gD-1 downstream primer, 5' CCCAAGCTTCCCGCAGACCTGACCCCC 3' (SEQ ID NO: 9) which corresponds to nucleotides 1449 to 1466 of SEQ ID NO: 3 and which contains the recognition sequence for Hindlll (underlined), to amplify sequences from template plasmid pRE4. In both cases, twenty-five cycles of amplification were performed; in each cycle the template was denatured at 94 "C for 1 minute, primers were then annealed to the template at 55 ° C for 2 minutes, and the bound primers were extended at 72 °C for 3 minutes. The 5' and the 3' DNA segments were purified by electroelution. The segments were linked by an additional round of amplification wherein the gD-1 upstream and downstream primers and the 5' and the 3' segments as templates. The mutant DNA product was electroeluted, Hindlll digested and ligated with pRSVnt EPA. The proper orientation of the insert was determined by restriction enzyme analysis. The resulting plasmid pHC237 encodes full length gD-1 with arginine, lysine, isoleucine, and phenylalanine residues inserted after amino acid 299. Third, the BamΗl-Bglϊl fragment of pHC236 including 5' gD coding sequences was ligated to the BgKl-BamHI fragment of pHC237 including 3' gD coding sequences to generate the plasmid pHC240. This plasmid encodes the variant gD molecule gD-l(Δ290-299). The DNA and deduced amino acid sequences of gD- 1(Δ290-299) are set out in SEQ ID NOs: 10 and 11, respectively. Fourth, in a further variant of this molecule, the plasmid pHC240 was further engineered to produce the plasmid designated pAN258, which contains six histidine residues at its carboxy terminus and is soluble in an aqueous medium. Amino acid residues 300 through 306 of the wild-type gD-1 protein corresponded to amino acid residues 295-300 of the variant. Thus, a soluble form of variant gD-l(Δ290-299) was generated by PCR using plasmid pHC240 as template. Primers 5' TTTTGGATCCCAAATATGCCTTGGCGGATG 3' (SEQ ID NO: 12), which corresponds to nucleotides 316 to 334 of SEQ ID NO: 10 and contains a BamHI restriction site (underlined), and 5' GGCGCTGCGGAATGGTAGTAGTAGTAGTAATTGACGTCTTTT 3' (SEQ ID NO: 13), which corresponds to nucleotides 1202 to 1215 of SEQ ID NO: 10 and encodes a tyrosine residue and a six residue poly histidine tail (double underlined) and a PstI site (underlined), were used to truncate the encoded protein at amino acid 306 of SEQ ID NO: 11. Forty-five amplification cycles of 1 minute at 94"C, 30 seconds at 52 β C, and 2 minutes at 75°C were performed. The amplification products were examined on a 1 % agarose gel and the desired fragment was purified from the gel. The fragment was then digested with Ba iHl and PstI and inserted into similarly digested plasmid pVTBac [Tessier et al. , supra] for use in baculovirus expression. The plasmid pVTBac includes a melittin signal peptide and cleavage site (two residues upstream of the gD-1 mature protein initial lysine residue) to allow for secretion of the protein of interest from baculovirus-infected host cells. The resulting plasmid pAN258 encoded the region IV variant gD molecule with a carboxy-terminal truncation which was designated gD-l(Δ290-299t). The DNA and deduced amino acid sequences of the variant are set out in SEQ ID NOs: 1 and 2, respectively. Genes encoding full length and truncated region I, II, and III HSV gD- 1 variant molecules were constructed by similar standard recombinant DNA methods. The full length variants were designated gD-l(v34), gD-l(vl26), and gD-l(v243), respectively, and the truncated variants were designated gD-l(v34t), gD-l(vl26t), gD-l(v243t), gD-l(Δ277-290t), and gD-l(Δ277-300t), respectively. The full length and truncated variants gD-l(v34) and gD-l(v34t) contained a glycine at position 34 instead of the valine residue at position 34 of wild type gD-1 and lysine, isoleucine, phenylalanine, and leucine residues inserted after the glycine; gD-l(vl26) and gD- l(vl26t) contained a glycine at position 126 instead of the alanine residue at position 126 of wild type gD-1 and contained lysine, isoleucine, phenylalanine and proline residues inserted after the glycine; and gD-l(v243) and gD-l(v243t) contained a glycine residue at position 243 and contained glycine, arginine, serine, and serine residues inserted after the glycine. The truncated variants gD-l(Δ277-290t) and gD- l(Δ277-300t) lacked Patton residues 277 to 290 and 277 to 300, respectively; were truncated at Patton amino acid 306; and contained five additional histidine residues after at the carboxy terminus. A gene encoding a secreted version of wild type gD-1 designated gD-l(306t) containing Patton strain gD-1 residues 1 through 307 and five additional histine residues at the carboxy terminus was also constructed to provide a soluble control protein. FIGURE 1 is a schematic drawing which shows significant features of wild type gD-1 and truncated wild type gD-l(306t) and gD-l(Δ290-299t) molecules cysteine residues (c), disulfide bonds (S-S), and potential N-linked glycosylation sites. Example 2 Full length variant gD molecules were expressed in COS-1 or L cells transfected with the genes described in Example 1 by a modified calcium phosphate- DNA coprecipitation method described in Cohen et al. , supra. Full-length variants may also be expressed using baculovirus vectors in Sf9 cells [Landolfi et al , Vaccine, 11: 407-414 (1993)]. Truncated variant gD molecules were expressed in Sf9 cells. pVTbac vectors containing the genes encoding the variants were cotransfected with wild type baculovirus DNA in the form of BaculoGold (Pharmingen, San Diego, CA) linear DNA into Sf9 cells. Cotransfection was mediated by cationic liposomes (Lipofectin, GIBCO, Grand Island, NY) according to the manufacturer's specifications. Recombinant virus stocks were prepared essentially as described in Sisk et al. , supra. To express the truncated variant gD molecules, suspension cultures of Sf9 cells were infected with one of the recombinant virus stocks, cells were pelleted and the medium containing the variant gD molecules was subjected to immunoaffinity chromatography on a DL-6 (produced by hybridoma ATCC HB 8606) IgG Sepharose column as described in Sisk et al , supra to purify the variants. Variants gD-l(Δ277-290t) and gD-l(Δ277-300t), in which the epitope recognized by the DL-6 antibody was deleted, can be purified by immunoaffinity chromatography using antibodies specific for other epitopes of gD-1 such as antibodies described in Muggeridge et al. , Chapter 20 in van Regenmortel and Neurath, Eds. , Immunochemistry of Viruses, II, The Basis for Serodiagnosis and Vaccines, Elsevier Science Publishers (1990). Example 3 The structural and functional characteristics of the variant gD-1 molecules in comparison to wild type gD-1 were examined by various assays. The structural integrity of the variants was assessed by measuring the ability of each variant to bind to monoclonal antibodies recognizing discontinuous gD- 1 epitopes as a reflection of conformation; studying cell surface expression as a reflection of proper transport, and measuring protein aggregation as an indication of improper folding. The variants were also examined by circular dichroism. Five monoclonal antibodies (AP7, HD1, DL11, ABD, and DL2) recognizing different gD-1 discontinuous epitopes (Chiang et al , supra and Muggeridge et al. , supra) were used to examine the antigenic conformation of the variants. Cytoplasmic extracts containing full length variants were prepared from COS-1 cells at 40 hours posttransfection and assayed for antibody binding by Western blot. Baculovirus-produced truncated region I, II, III, and IV variants were assayed for antibody binding by ELISA. Binding of the antibodies to the truncated variants was similar to that seen for the full length variant molecules. In each case, the variant proteins were still bound by one or more of the monoclonal antibodies which recognize conformational epitopes indicating that the conformation of the gD variants was not grossly altered by the mutations. The region IV variant was bound by all but monoclonal antibody AP7 indicating that its conformation was the most similar to wild type gD. Given the extensive homology between wild type gD-1 and gD-2 [see FIGURE 2 which presents an alignment of the Patton strain gD-1 amino acid sequence (SEQ ID NO: 4) and the strain 333 gD-2 amino acid sequence (SEQ ID NO: 15)], the invention specifically contemplates that region IV gD-2 variants which contain mutations coπesponding to the gD-1 mutations described herein will have similar characteristics. When examined by circular dichroism, the region III and IV variants [gD-l(v243) and gD-l(Δ290-299t)] resembled gD-l(306t) in secondary structure, but the region I variant gD-l(v34) and the region II variant gD-l(vl26) differed in secondary structure. Finally, to examine the functional characteristics of the variant gD-1 molecules, the ability of the variants to rescue the infectivity of the gD-null virus F- gD 3 was assayed. The virus replicates in and forms plaques on VD60 cells which contain an integrated gD gene under the control of its own promoter. L cells transiently transfected with genes encoding a variant were then superinfected with F- gD3. Pseudotype particles were harvested and titered on VD60 cells. The number of plaques measure the extent to which the variant gD molecule rescued the infectivity of the null virus. When infectivity was rescued with the wild type gD gene, the yields were typically 2 x IO 6 PFU of progeny extracellular virus and 10° PFU of intracellular virus. Virus yields from wild-type gD were considered to be 100%. The region I, II, III, and IV variant gD-1 molecules were able to complement the null virus in some cases only at very low levels and in other cases not at all. These experiments indicated that while mutations in regions I, II, III, and IV had minor effects on the conformation of the variant gD molecules, the mutations still had profound effects on the functional characteristics of the molecules. Example 4 Functional properties ofthe baculovirus-produced truncated variant gD molecules were examined further in cell binding and HSV blocking assays. Binding of the variants to fixed Vero and BHK cells was measured by ELISA as described in Tal-Singer et al, supra. Truncated wild type gD-l(306t) and the truncated region I, II, III, and IV variant gD-1 molecules all bound to the fixed cells. The ability of the variants to block HSV-1 infection of susceptible cells was measured by three assays diagrammed in FIGURE 3, a plaque formation assay, a cell to cell spread assay, and an HSV-l/lacZ+ entry assay. The plaque formation assays were performed as described in Tal-Singer et al. , supra. Briefly Vero or BHK cell monolayers in 48-well plates were treated with region I, II, III, or IV variant or BSA diluted in 5% DMEM for 1.5 hours at 4°C. HSV-1 strain NS was added at 50 PFU per well for 1.5 hours and then treated with variant or BSA. After 24 hours at 37° C, the medium was removed and the cells were fixed and air dried. Virus titers were determined by immunoperoxidase assay and the amount of variant needed to block HSV infection was titrated. Results of the assays for the truncated wild type gD-1 molecule and the gD-l(Δ290-299t) variant are presented in FIGURES 4 A and 4B. If the amount of wild type gD-l(306t) needed to block infection by more than 60% is equal to 1, the region I variant gD-l(v34t) failed to block infection at all, the region III variant gD-l(v243t) blocked one-half as well as wild type, and the region II variant gD-l(vl26t) blocked as well as wild type. In comparison to these results, a significant increase in ability to block infection was exhibited by the region IV variant gD-l(Δ290-299t). It was able to block infection by HSV-1 about 400 times better than wild type gD-1. When variant gD-l(Δ290-299t) was denatured by heating to 65 °C for five minutes and then chilled to 4°C before the plaque formation assay was performed, the variant was incapable of blocking HSV-1 infection. Heat denaturation destroys secondary and tertiary structure of gD but leaves disulfide bonds intact. See FIGURE 5. The region IV variant gD-l(Δ290-299t) exhibited similar blocking effects in cell to cell spread and HSV/lacZ+ entry assays. The cell to cell spread assay was performed in the same manner as the plaque formation assay, except that the gD proteins were not added until three hours after cells were infected with HSV-1. Results of the assays are presented in FIGURE 6. In HSV/lacZ+ assays, confluent Vero cell monolayers in 96 well culture plates were preincubated with variant diluted in DMEM (BioWhittaker, Walkersville, MD) + 5% fetal bovine serum for 90 minutes at 4°C. To each well, 1.5 x IO 4 PFU/well of 7134 virus, an HSV-1 KOS strain with both copies of ICPO gene replaced by E. coli lacZ gene [Cai et al, J. Virol, 63: 4579-4589 (1989)], conesponding to an MOI of about 0.4, was added for 90 minutes at 4°C. After four hours incubation at 37 °C the medium was removed and the cells were lysed with 0.5% NP40. The NP40 lysates were transfened to a new 96 well plate, β- galactosidase activity was detected by adding CPRG (Boehringer Mannheim, Indianapolis, IN) substrate solution. Absorbance was measured at 570 nm using a Microplate Biokinetics Reader (Bio-Tek Instruments, Winooski, VT). Results of the assay are presented in FIGURE 7. Results of the three types of assays are summarized in FIGURE 8 wherein micromolar amounts of protein necessary for 50% inhibition of 50 PFU HSV (or for 50% inhibition of 1.5x10* PFU as measured by beta-galatosidase production for "entry" values) are shown and wherein "NE" indicates the protein had no effect. It is clear that while the gD-1 variants exhibit similar conformations and cell binding properties that the region IV variant is a significantly more potent HSV inhibitory compound. Example 5 Baculovirus-produced region IV variant gD molecules of the invention were also examined in plaque formation assays as described in Example 4 for the ability to block infection of susceptible cells by different HSV-1 strains as well as two mutant HSV-1 strains, the infectivity of which is not blocked by wild type gD- l(306t). The various strains can be differentiated by comparison of their nucleotide and amino acid sequences. When the wild type gD-l(306t) and variant gD-1 molecule Δ290-299t were tested in plaque formation assays in which HSV-1 strains HFEM, KOS, and 17 were utilized, the variant gD-1 (Δ290-299t) molecule exhibited an enhanced inhibitory effect on each strain in comparison to the wild type gD-1. Compare FIGURES 9A (306t) and 9B (Δ290-299t). These results are consistent with the results presented for HSV-1 strain NS in the foregoing example. Moreover, the variant gD-l(Δ290-299t) was able to inhibit infection by two mutant HSV-1 strains ridl and rid2 (FIGURE 10) while the wild type molecule could not. The ridl and rid2 mutant strains were generated by passaging HSV-1 strain KOS on gD-expressing cells to select viruses that could overcome the ability of wild type gD-1 to inhibit infectivity of the viruses. See Dean et al, Virology, 199: 67-80 (1994). Neither wild type gD-1 (data not shown) nor the variant gD-l(Δ290-299t) was able to inhibit infection by the mutant HSV-1 strain ANG (FIGURE 9). The ANG virus strain is described in Dean et al, J. Virol , 69(8): 5171-5176 (1995) as a strain that is almost completely resistant to gD-mediated interference (i.e., the ANG virus can infect cells expressing gD). Table 1 below sets out the concentration of gD-1 molecule necessary for 50% inhibition of 50 PFU HSV as measured in the plaque formation assays. In the Table, "NE" indicates the molecule had no effect on the infectivity of the indicated virus strain and "--" indicates the value cannot be calculated. Table 1 IC 50 (nM) Virus Strain gD-l(306t) gD-l(Δ290-299t) Fold difference HSV-1 NS 1600 4.0 400 KOS 218 2.6 84 17 139 4.8 29 HFEM 180 16.4 11 rid2 NE 150 — HSV-2 333 164 1.5 109 The region IV variant gD-l(Δ290-299t) can thus inhibit herpesviruses more effectively than wild type gD-2 protein and can inhibit herpesviruses that wild type gD-l(306t) cannot. Example 6 The ability of gD-1 molecules to inhibit other herpesviruses was also investigated. The gD-1 variant (Δ290-299t) molecule was tested in plaque formation assays (Example 4) involving HSV-2 strain 333 and bovine herpes 1 (BHV-1), a related alphaherpesvirus. As shown in FIGURE 11, the Δ290-299t variant inhibited HSV-1 but not BHV-1, demonstrating that its inhibitory ability is specific for HSV infection. Moreover, as shown in FIGURE 12, the gD-1 variant (Δ290-299t) molecule inhibited HSV-2 at an IC 50 level of 1.5nm while wild type gD-1 inhibited HSV-2 at an IC 50 level of 164nm. Thus, gD-l(Δ290-299t) had a 109-fold greater effect on HSV-2 plaque formation than did wild type gD-l(306t). Example 7 Polyclonal antibodies specific for wild type gD-l(306t) and the gD-1 variant (Δ290-299t) molecule were elicited in rabbits. The polyclonal antbodies were then assayed for the ability to neutralize HSV-1 infectivity. Two rabbits (designated R122 and R123) were intially immunized with an inoculation of 100 μg purified gD-l(306t), while two rabbits (designated R130 and R131) were initially immunized with an inoculation of 100 μg purified gD-l(Δ299- 299t). Both sets of initial inocula were mixed at a 1:1 ratio with Freund's complete adjuvant and given subcutaneuosly in inguinal and axillary regions and intramuscularly in hind limbs. No more than 0.2 ml per subcutaneous site and no more than 0.5ml per intramuscular site were administered. After two weeks, each rabbit was boosted with 50 μg of its respective antigen mixed at a 1:1 ratio with Freund's incomplete adjuvant. The first boosts (and all subsequent boosts) were given subcutaneously along the back and intramuscularly in the hind limbs. No more than 0.2 ml per subcutaneous site and no more than 0.5 ml per intramuscular site were administered. The rabbits were similarly boosted at weeks 3, 7, 10, and 14. Tests bleeds were taken at weeks 5, 8, 11, and 16. Neutralization assays were performed with polyclonal sera from the fourth bleed. The polyclonal antibodies were assayed for the ability to neutralize HSV-1 infectivity. The ability of the antibodies to inhibit infectivity indicates that the antigenic conformation of the variant gD molecule is similar to the wild type gD molecule. Wild type gD is known to induce production of potent virus-neutralizing antibodies when injected into animals. The rabbit sera were heat treated at 56 °C for 30 minutes to inactivate complement. Vero cells were grown in 48 well plates until the monoplayer was nearly confluent. Serial two-fold dilutions of serum were prepared in DMEM medium containing 5% fetal bovine serum (FBS), then mixed with an equal volume of HSV-1 strain KOS in the same medium. The virus concentration was adjusted to give approximately 100 plaques per well of the 48 well plate in the absence of neutralizing antibody. Each virus-rabbit serum mixture was plated in duplicate onto the Vero cell monolayers and incubated for 1 hour at 37°C. Each well of the 48 well plate was then overlaid with medium and incubated at 37 °C until visible plaques developed. The medium was removed and the cells were fixed with a mixture of methanol and acetone and dried. Plaques were visualized by incubating the monolayers with a cocktail of antibodies to giycoproteins gD, gB and gC, then performing a "black plaque assay" using horseradish peroxidase conjugated protein A, followed by addition of the substrate 4-chloro-l -naphthol. Plaques were then counted. The results of the assays are presented in Table 2 below wherein the titer value is the dilution of antibody that reduced HSV-1 plaque number by 50%. Table 2 Polyclonal Antibody Antigen Neutralization titer R122 gD-l(306t) 640 R123 gD-l(306t) 1280 R130 gD-l(Δ290-299t) 1280 R131 gD-l(Δ290-299t) 640 Wild type and gD-l(Δ290-299t) rabbit polyclonal anitsera had similar neutralization titers suggests that gD-l(Δ290-299t) retains wild type immunogencity. This result is consistent with the analyses of three dimensional structure presented in Example 3. Example 8 Monoclonal antibodies specific for gD-1 variants of the invention may be generated as follows. To generate monoclonal antibodies, female Balb/c mice are immunized with 50 μg of a variant gD-1 molecule. The immunogen is prepared in complete Freund's adjuvant, with subsequent boosts (25 μg antigen in incomplete Freund's) at about 21 day intervals. Cell lines producing monoclonal antibodies are isolated as follows. Briefly a single cell suspension is formed by suspending immunized mouse spleen cells in serum free RPMI 1640, supplemented with 2mM L-glutamine, ImM sodium pyruvate, 100 units/ml penicillin, and 100 μg/ml streptomycin (RPMI) (Gibco, Canada). The cell suspension is filtered through sterile 70-mesh Nitex cell strainer (Becton Dickinson, Parsippany, NJ), and washed twice by centrifuging at 200 g for 5 minutes and resuspending the pellet in 20 ml serum free RPMI. Thymocytes taken from three naive Balb/c mice are prepared in this manner. NS-1 myeloma cells kept in log phase in RPMI with 11 % fetal bovine serum (FBS) (Hyclone Laboratories, Inc. , Logan, UT) for three days prior to fusion, are centrifuged at 200 g for 5 minutes, and the pellet is washed twice as described in the foregoing paragraph. After washing, each cell suspension is brought to a final volume of 10 ml in serum free RPMI, and 10 μl was diluted 10:100. Twenty μl of each dilution is removed, mixed with 20 μl 0.4% trypan blue stain in 0.85% saline (Gibco), loaded onto a hemacytometer and counted. Two x 10 8 spleen cells are combined with 4 x IO 7 NS-1 cells, centrifuged, and the supernatant was aspirated. The cell pellet is dislodged by tapping the tube and 2 ml of 37° C PEG 1500 (50% in 75mM Hepes, pH 8.0) (Boehringer Mannheim) is added with stirring over the course of 1 minute, followed by adding 14 ml of serum free RPMI over 7 minutes. An additional 16 ml RPMI is added and the cells are centrifuged at 200 g for 10 minutes. After discarding the supernatant, the pellet is resuspended in 200 ml RPMI containing 15% FBS, 100μM sodium hypoxanthine, 0.4μM aminopterin, 16μM thymidine (HAT) (Gibco), 25 units/ml IL-6 (Mallinckrodt, Folcrost, PA), and 1.5 x 10° thymocytes/ml. The suspension is dispensed into ten 96-well flat bottom tissue culture plates at 200 μl/well. Cells in plates are fed 3 to 4 times between fusing and screening by aspirating approximately half the medium from each well with an 18 G needle and replenishing plating medium described above except containing 10 units/ml IL-6 and lacking thymocytes. Fusions are screened when cell growth reaches 60-80 % confluency (day 7 to 9) by ELISA on the particular gD-1 variant that was used as the immunogen in comparison to wild type gD-1 and/or other variant gD-1 molecules. Immunlon 4 plates (Dynatech, Cambridge, MA) are coated at 4°C overnight with 100 ng/well protein in 30mM carbonate buffer, pH 9.6. Plates are blocked with 100 μg/well 0.5% fish skin gelatin in PBS for one hour at 37° C, washed 3 times with PBS, 0.05% Tween 20 (PBST) and 50 μl culture supernatant is added. After incubation at 37° C for 30 minutes, and washing as described above, 50 μl of horseradish peroxidase conjugated goat anti-mouse IgG(fc) (Jackson ImmunoResearch, West Grove, PA) diluted 1:3500 in PBST is added. Plates are incubated as above, washed 4 times with PBST and 100 μl substrate, consisting of 1 mg/ml o-phenyl diamine and 0.1. μl/ml H 2 O 2 in lOOmM citrate, pH 4.5, was added. The color reaction is stopped in 5-10 minutes with the addition of 50 μl of 15% H 2 SO 4 . A 490 is read on a plate reader. Wells showing preferential reactivity the variant preparation of interest over the control preparations are plated at limiting dilutions to isolate monoclonal cell lines producing antibodies specific for that variant gD-1 molecule. While the present invention has been described in terms of specific embodiments, it is understood that variations and modifications will occur to those skilled in the art. For example, conesponding region IV variant gD-2 molecules and other region IV variant gD-1 molecules will be constructed and tested in the same assays for the ability to block HSV-1 and/or HSV-2 infection. Other variants specifically contemplated include, but are not limited to, variants comprising insertions at gD-1 residue 290, and variants comprising insertions at gD-1 residue 300. These variants may be made as either full-length or carboxy terminal truncated gD molecules. Accordingly only such limitations as appear in the claims should be placed on the invention.
