Skin is a unique target for vaccination. Targeting keratinocytes to produce proinflammatory mediators improve immunity rational approach vaccine design. Keratinocytes genetically engineered overexpress the stress response related transcription factor x-box binding protein 1 (XBP1) increased production of and co-delivered antigen. Keratinocyte-specific overexpression XBP1 through cutaneous genet...
background: the thiol-specific antioxidant (tsa) is an antigen of leishmania major which is believed to be the most promising molecule as a vaccine candidate against leishmaniasis. objectives: in this study, we investigated the protective efficacy of tsa-based dna vaccine against l. major infection. materials and methods: recombinant plasmid construction tsa (pctsa) was prepared and transfected...
High levels of infused anti-human immunodeficiency virus type 1 (HIV-1) neutralizing monoclonal antibodies (MAbs) can completely protect macaque monkeys against mucosal chimeric simian-human immunodeficiency virus (SHIV) infection. Antibody levels below the protective threshold do not prevent infection but can substantially reduce plasma viremia. To assess if HIV-1/SIV-specific cellular immunit...
background hypervariability of hcv proteins is an important obstacle to design an efficient vaccine for hcv infection. multi-epitope vaccines containing conserved epitopes of the virus could be a promising approach for protection against hcv. objectives cellular and humoral immune responses against multi-epitope dna and peptide vaccines were evaluated in balb/c mice. materials and methods in th...
The induction of systemic (IgG) and mucosal (IgA) antibody responses against the colonization factor I antigen (CFA/I) of enterotoxigenic Escherichia coli (ETEC) was evaluated in mice primed with an intramuscularly delivered CFA/I-encoding DNA vaccine followed by two oral immunizations with a live recombinant Salmonella typhimurium vaccine strain expressing the ETEC antigen. The booster effect ...
Transmissible spongiform encephalopathies (TSEs) can be ameliorated by prion protein (PrP)-specific antibodies, but active immunization is complicated by immune tolerance to the normal cellular host protein (PrP(C)). Here, we show that DNA immunization of wild-type mice can break immune tolerance against the prion protein, resulting in the induction of PrP-specific antibody and T-cell responses...
Genital infections with human papillomavirus (HPV) are increasingly recognized as a significant source of human disease; HPV is now implicated in up to 90% of cervical carcinomas. Neutralizing antibodies against papillomaviruses recognize conformational epitopes formed when viral capsid proteins assemble into virions or virus-like particles. Immunization with plasmid DNA encoding the major vira...
DNA-based immunization has initiated a new era of vaccine research. One of the main goals of gene vaccine development is the control of the levels of expression in vivo for efficient immunization. Modifying the vector to modulate expression or immunogenicity is of critical importance for the improvement of DNA vaccines. The most frequently used vectors for genetic immunization are plasmids. In ...
We tested the concept of combining DNA with protein to improve anti-HIV Env systemic and mucosal humoral immune responses. Rhesus macaques were vaccinated with DNA, DNA&protein co-immunization or DNA prime followed by protein boost, and the magnitude and mucosal dissemination of the antibody responses were monitored in both plasma and mucosal secretions. We achieved induction of robust humoral ...
