Soluble or sub-unit protein vaccines alone are incapable of generating antigen-specific cellular immune responses. This failure can be attributed to the manner in which the immune system processes antigen; endogenous antigens are cycled through the MHC class I pathway to stimulate CD8 + restricted responses and exogenous antigens are processed through the MHC class II pathway to generate humoral...
Tomatine adjuvant, consisting of tomatine, n-octyl-β-d-glucopyranoside (OGP), phosphatidylethanolamine and cholesterol is unique in that when combined with soluble protein antigen it elicits a cytotoxic T lymphocyte (CTL) response in immunized animals. The mechanisms underlying this property are unknown. In an attempt to understand how tomatine activates cellular immunity, we examined its potential...
Many vaccine adjuvants contain surface-active agents, but the immunological roles played by these components have been essentially ignored. The objective of this study was to examine possible apoptotic and necrotic effects of the surface-active agents, Pluronic L121 and Tween 80, which are components of L121-adjuvant (a formulation we synthesized with the aim of representing several commercially produced...
The tomatine adjuvant, consisting of tomatine, n-octyl-β-d-glucopyranoside, phosphatidylethanolamine, cholesterol, and ovalbumin, has recently been shown to potentiate the immunogenicity of protein antigen and elicit cytotoxic T-lymphocyte responses in immunized animals. The physicochemical properties of tomatine adjuvant have not been characterized. The aim of this study was to examine the microstructure...
The gE glycoprotein of varicella zoster virus (VZV) is involved with cell entry and it is the most abundant glycoprotein produced in VZV-infected cells. It is also the first glycoprotein to be recognized by the immune system and induces neutralizing antibodies and cellular immunity. We have shown previously that immunization with a DNA vaccine encoding full length gE induces high antibody titres in...
In this study we constructed a plasmid containing the gene encoding varicella-zoster virus transmembrane glycoprotein gE (VZV gE) and evaluated its utility for DNA immunization in mice. Our initial work demonstrates that intramuscular and subcutaneous injection of VZV gE DNA, without the use of costimulatory molecules or other adjuvant materials, results in the generation of antigen-specific antibodies...
Presentation of peptide on MHC class I molecules is essential to elicit cytolytic T cell (CTL) activity. Such peptides are a result of the cytosolic, or class I, antigen processing pathway. Due to the segregation of the class I and the exogenous processing pathway, soluble protein cannot enter the class I pathway and is thus incapable of inducing CTL. However careful formulation with adjuvants can...
