We created and produced a novel self-assembling nanoparticle platform for delivery of peptide epitopes that induces CD8 + and CD4 + T cells that are protective against Toxoplasma gondii infection. These self-assembling polypeptide nanoparticles (SAPNs) are composed of linear peptide (LP) monomers which contain two coiled-coil oligomerization domains, the dense granule 7 (GRA7 20–28...
Schistosomasis is a world-wide parasitic disease. Although chemotherapy is the main treatment method for schistosomasis currently, it cannot prevent schistosome reinfection. Up to now no effective vaccine is available to prevent schistosomiasis. Dendritic cells (DCs) are one of the key players in the cellular immune response and play an important role in antigen presentation as antigen-presenting...
110 children who were given the complete course of the inactivated hepatitis A vaccine (Havrix™) were followed up 10 years later. Age-matched healthy children who were not inoculated served as controls. One month after two primary injections, all children were positive for serum antibody. After 10 years, 99.09% of inoculated children remained positive for serum anti-HAV antibody, with a geometric...
Epitope vaccine is a promising option for therapeutic vaccination against Helicobacter pylori (H. pylori) infection. In this study, we constructed a multi-epitope vaccine with five epitopes and mucosal adjuvant E. coli heat-labile enterotoxin B subunit (LTB) named HUepi-LTB and evaluated its therapeutic effect against H. pylori infection in BALB/c mice model. HUepi-LTB containing three Th epitopes...
Urease plays a crucial role in the survival and pathogenesis of Helicobacter pylori (H. pylori), and antibody neutralizing the urease activity may be implicated for the protection against H. pylori infection. Previously, a neutralizing monoclonal antibody (MAb) 6E6 against UreB of H. pylori was developed. In this work, we try to identify the B-cell epitope recognized by neutralizing MAb 6E6. Following...
Mucosal immune responses induced by HIV-1 vaccines are likely critical for prevention. We report a Phase 1 safety and immunogenicity trial in eight participants using the vaccinia-based TBC-3B vaccine given subcutaneously to determine the relationship between HIV-1 specific systemic and gastrointestinal mucosal responses. Across all subjects, detectable levels of blood vaccinia- and HIV-1-specific...
CD4 + T cells play important roles in protection against Helicobacter pylori (H. pylori) infection. In order to better understand the immune responses of H. pylori infection and improve immune interventions against this pathogen, we identified the Th epitopes in UreB of H. pylori, an excellent vaccine candidate antigen. By using the RANKPEP prediction algorithm, we have identified and characterized...
