Paragraph: Background: Chronic Hepatitis B (CHB) remains a major problem for global public health. Viral persistence and immune defects are the two major reasons for CHB, and it was hypothesized that based on a transient clearance of serum viral DNA and HBsAg "window stage", active immunization against hepatitis B virus (HBV) might initiate effective host immune responses versus HBV to achieve functional cure of CHB. Methods: Two experimental mouse models that mice hydrodynamic injected HBV DNA or infected with recombinant AAV/HBV were used. The "sandwich" therapeutic effect by using a potent human anti-HBsAg neutralizing monoclonal antibody (G12) in combination with antiviral drug tenofovir disoproxil fumarate (TDF), followed by active immunization with HBsAg-HBsAb (mYIC) was evaluated. Findings: A single G12 injection rapidly cleared serum HBsAg in HDI-HBV carrier mice, with a synergistic effect in decreasing viral DNA load when TDF was given orally. When both serum viral DNA and HBsAg load became low or undetectable, mYIC was administered. A more effective clearance of viral DNA and HBsAg was observed and serum HBsAb was developed only in these "sandwich"-treated mice. Efficient intrahepatic anti-HBV immune responses were also observed in these mice, including the formation of aggregates of myeloid cells with CD8 + T cells and increased TNF-α, granzyme B production. The "sandwich" combination therapy not only efficiently decreased HBsAg and HBV DNA levels but also induced effective cellular and humoral immunity, which may result in functional cure of CHB. Research in context section Persistence of HBV cccDNA and various host immune defects were shown as the two main obstacles for HBV clearance. Blocking a single target will not be sufficient to achieve functional cure of CHB.

Therapeutic vaccination for CHB showed substantial efficacy. A humanized HBsAb G12 could efficiently block HBV infection and decrease HBsAg level in mice model. This research showed that when both serum viral DNA and HB-sAg load became low or undetectable by antiviral and HBsAb treatment, therapeutic vaccine (mYIC) add on induced effective, host humoral and intrahepatic cellular anti-HBV immune responses, with more rapid and efficient clearance of HBV and HBsAg. Based on optimized antiviral treatment with potent human HB-sAb to rapidly decrease serum HBsAg, followed by boosting host with active immunization provides a novel strategy for functional cure of CHB.

Paragraph: Plasmodium falciparum erythrocyte invasion is a multistep process that involves a spectrum of interactions that are not well characterized. We have characterized a 113-kDa immunogenic protein, PF3D7_1431400 (PF14_0293), that possesses coiled-coil structures. The protein is localized on the surfaces of both merozoites and gametocytes, hence the name Plasmodium falciparum surface-related antigen (PfSRA). The processed 32-kDa fragment of PfSRA binds normal human erythrocytes with different sensitivities to enzyme treatments. Temporal imaging from initial attachment to internalization of viable merozoites revealed that a fragment of PfSRA, along with PfMSP1 19, is internalized after invasion. Moreover, parasite growth inhibition assays showed that PfSRA P1 antibodies potently inhibited erythrocyte invasion of both sialic acid-dependent and -independent parasite strains. Also, immunoepidemiological studies show that malaria-infected populations have naturally acquired antibodies against PfSRA. Overall, the results demonstrate that PfSRA has the structural and functional characteristics of a very promising target for vaccine development.

Paragraph: Mouse Hepatitis Virus (MHV) is a single-stranded positive sense RNA virus with the ability to promote acute and chronic diseases in mice. The MHV spike protein (S) is a major virulence determinant which in addition to binding to cellular receptors to mediate cell entry and facilitate virus spread to adjacent cells by cell-cell fusion, also is a molecular mimic of the Fc␥RII receptor. This molecular mimicry of Fc␥RII by the MHV S protein is also exhibited by other lineage 2a betacoronaviruses, with the exception of the human coronavirus HCoV-OC43. In this work we undertook a mutational analysis to attempt to identify specific amino acid sequences within the spike glycoprotein crucial for molecular mimicry of Fc␥RII. Although we were unsuccessful in isolating mutant viruses which were specifically defective in that property, we identified several mutations with interesting phenotypes. Mutation of the cysteine in position 547 to alanine and alanine replacements at residues 581-586 was lethal. Replacing proline 939 with the corresponding HCoV-OC43 residue, leucine, decreased the ability MHV to induce cell-cell fusion, providing experimental support for an earlier proposal that residues 929-944 make up the fusion peptide of the MHV S protein.
