Efficacy of DNA and fowlpox virus priming/boosting vaccines for simian/human immunodeficiency virus.
Further advances are required in understanding protection from AIDS by T-cell immunity. We analyzed a set of multigenic simian/human immunodeficiency virus (SHIV) DNA and fowlpox virus priming and boosting vaccines for immunogenicity and protective efficacy in outbred pigtail macaques. The number of vaccinations required, the effect of DNA vaccination alone, and the effect of cytokine (gamma in...
BACKGROUND CD8(+) cytotoxic T lymphocytes (CTLs) are crucial for eliminating hepatitis B virus (HBV) infected cells. DNA vaccination, a novel therapeutic strategy for chronic virus infection, has been shown to induce CTL responses. However, accumulated data have shown that CTLs could not be effectively induced by HBV DNA vaccination. METHODOLOGY/PRINCIPAL FINDINGS Here, we report that praziqu...
Vaccination against AIDS is hampered by great diversity between human immunodeficiency virus (HIV) strains. Heterologous B-subtype-based simian-human immunodeficiency virus (SHIV) DNA prime and poxvirus boost vaccine regimens can induce partial, T-cell-mediated, protective immunity in macaques. We analyzed a set of DNA, recombinant fowlpox viruses (FPV), and vaccinia viruses (VV) expressing sub...
Effective vaccination using in vitro peptide-loaded heat-shock proteins (HSP), tumor-derived HSP and HSP fusion proteins has been shown in viral, parasite and tumor model systems. We demonstrate protective DNA vaccination using gp96-peptide fusion proteins against the intracellular bacterial pathogen Listeria monocytogenes in a mouse model. In contrast to previous studies using pathogen-derived...
Effective vaccination using in vitro peptide-loaded heat shock proteins, tumor-derived heat shock proteins, and heat shock-fusion proteins has been shown in viral, parasite, and tumor model systems. We demonstrate protective DNA-vaccination using gp96-peptide fusion proteins against the intracellular bacterial pathogen Listeria monocytogenes in a mouse model. In contrast to previous studies usi...
Therapeutic vaccination against idiotype is a promising strategy for immunotherapy of B-cell malignancies. We have previously shown that CDR3-based DNA immunization can induce immune response against lymphoma and explored this strategy to provide protection in a murine B-cell lymphoma model. Here we performed vaccination employing as immunogen a naked DNA fusion product. The DNA vaccine was gen...
induction of antibodies against key neutralizing epitopes by HIV-1 gp120 DNA prime-protein boost vaccination compared to gp120 protein only vaccination" (2008). GSBS Student Publications. 353.
BACKGROUND Major histocompatibility complex (MHC) antigens are important for alloimmune responses as well as immune tolerance. Previous studies have shown that presentation of donor MHC antigens by donor-specific transfusion prior to or upon transplantation promotes transplant tolerance induced by other agents. However, it is unclear whether presentation of donor MHC antigens by DNA vaccination...
Vaccination with DNA and recombinant vaccinia viruses (rec.VV) has been studied with the coxsackievirus B3 (CVB3) model system. Plasmids encoding all structural proteins of CVB3, when injected intramuscularly, induced only low levels of virus-specific antibodies. However, DNA vaccination with the major structural protein VP1 protected 72.2% of mice from lethal challenge, whereas VP1 expressed b...
Abstract Background and objectives: Hepatitis B virus infection is a major health problem in worldwide. The prevalence of Occult and chronic HBV in hemodialysis patients is higher than standard in developing countries. People with occult HBV are negative for HBV surface antigen (HBsAg) but positive for HBV-DNA. We aimed to evaluate occult hepatitis B infection in patients under hemodialysis in ...
