Abstract: Following HBV vaccination, the anamnestic response rate in HIV+ patients with isolated anti-HBc and negative anti-HBe test is low and comparable to that seen in anti-HBc– subjects. This finding suggests that anti-HBc alone may not be a reliable screening test to assess protection from HBV infection in HIV+ subjects. Te ...

Abstract: <p><b>BACKGROUND:</b> HIV envelope derived vaccines have been shown to induce partial to complete protection against infection in the chimpanzee model. Therefore, it was of interest to determine the type of immune response that was persistent in chimpanzees either immunized 6 to 12 years ago or those that resisted po ...

Abstract: Recent evidence suggests that after repeated stimulations with inactivated C. albicans (CA) cells, CD2F1 mice respond with a cytokine pattern typical of T-helper 1 (ThI) subset development. The purpose of this study was to analyse the sequence of immunological events which, soon after priming mice with CA, lead to the ...

Abstract: BACKGROUND: DermaVir is a novel topical DNA vaccine expressing structural and regulatory gene products in dendritic cells (DC) that polarize naïve T cells towards a Th1 response. Based on data showing that DermaVir therapeutic immunization induced T-cell mediated immune responses and inhibited viral load rebound in chr ...

Abstract: In a previous work we selected montanide ISA720 (M-ISA720) among different adjuvants for the vaccination with a V3 loop based multi-epitope polypeptide TAB9. In this paper we present the evaluation of the toxicity and immunogenicity of this formulation in non-human primates. TAB9 in M-ISA720 was highly immunogenic in ...

Abstract: CD4 T cells play a central role in viral immunity. They provide help for B cells and CD8 T cells and can act as effectors themselves. Despite their importance, relatively little is known about the magnitude and duration of virus-specific CD4 T-cell responses. In particular, it is not known whether both CD4 Th1 memory ...

Abstract: Sterile immunity was induced in rhesus monkeys against challenge with SHIV SF13 using an ISCOM based strategy. The vaccine formulation and immunization schedule would be acceptable for further study in human clinical trials. Immune responses were primed by i.m. injections of 30 micrograms of Chiron s recombinant HIV-1 ...

Abstract: We previously showed that immunization with HIV-1(LAI) gp160 vaccines, in a recombinant virus priming and subunit protein boosting regimen, protected macaques against SHIV HXBc2 challenge. In the present study, we examined the role of (1) priming with live recombinant vaccinia virus vs. subunit antigens, (2) surface a ...
