BACKGROUND Maternal antibody is the major form of protection against disease in early life; however, its presence interferes with active immunization of offspring. In order to overcome the immunosuppression caused by maternal antibody, several immune strategies were explored in this paper using mouse model and influenza vaccines. RESULTS The results showed that: i) when the offspring were imm...
Development of a vaccine against human immunodeficiency virus type 1 (HIV-1) is the main hope for controlling the acquired immunodeficiency syndrome pandemic. An ideal HIV vaccine should induce neutralizing antibodies, CD4+ helper T cells, and CD8+ cytotoxic T cells. While the induction of broadly neutralizing antibodies remains a highly challenging goal, there are a number of technologies capa...
1. When different forms of SARS coronavirus (SARS-CoV) spike protein-based vaccines for generation of a neutralising antibody response to SARS-CoV were injected into a mouse model, all the mice immunised with intramuscular tPA-optimised 800 DNA vaccine boosted with intraperitoneal recombinant spike polypeptide generated by Escherichia coli and intramuscular CTLA4Hinge SARS800 DNA vaccine booste...
Cellular immune responses, particularly those associated with CD3(+) CD8(+) cytotoxic T lymphocytes (CTL), play a primary role in controlling viral infection, including persistent infection with human immunodeficiency virus type 1 (HIV-1). Accordingly, recent HIV-1 vaccine research efforts have focused on establishing the optimal means of eliciting such antiviral CTL immune responses. We evalua...
background and aims: the aim of this study was cloning and expression of rabies virus glycoprotein by a eukaryotic expression plasmid pcdna3.1(+) in bsr cell line. this construct might be used for a potential dna vaccine. materials and methods: glycoprotein gene was synthesized and cloned into pbluescript vector and then sub cloned into eukaryotic expression vector (pcdna3.1(+)). after verifica...
Although the use of recombinant hepatitis B virus surface (HBsAg) protein vaccine has successfully reduced global hepatitis B infection, there are still a number of vaccine recipients who do not develop detectable antibody responses. Various novel vaccination approaches, including DNA vaccines, have been used to further improve the coverage of vaccine protection. Our previous studies demonstrat...
Several approaches have been explored to eradicate HIV; however, a multigene vaccine appears to be the best option, given their proven potential to elicit broad, effective responses in animal models. The Pr55Gag protein is an excellent vaccine candidate in its own right, given that it can assemble into large, enveloped, virus-like particles (VLPs) which are highly immunogenic, and can moreover ...
BACKGROUND An effective therapeutic vaccine that could augment immune control of HIV-1 replication may abrogate or delay the need for antiretroviral therapy. AIDS Clinical Trials Group (ACTG) A5187 was a phase I/II, randomized, placebo-controlled, double-blinded trial to evaluate the safety and immunogenicity of an HIV-1 DNA vaccine (VRC-HVDNA 009-00-VP) in subjects treated with antiretroviral ...
backgrounds: most of the hepatitis c virus (hcv) infections elicit poor immune responses and 75% to 85% of cases become chronic therefore, the development of an effective vaccine against hcv is of paramount importance. in this study, we aimed to evaluate co-administration of hcv non-structural protein 2 and il-12 dna vaccines in c57bl/6 mice. methods: a plasmid encoding full-length hcv ns2 prot...
