2004 MAR 31 - (NewsRx.com & NewsRx.net) -- Co-immunization with an HIV-1 Tat transduction peptide-rotavirus enterotoxin fusion protein stimulates a Th1 mucosal immune response in mice.
According to published research from the United States, "The cholera toxin B subunit (CTB) and a 12-aa HIV-1 Tat transduction peptide were genetically linked to a 90-aa peptide from the murine rotavirus non-structural enterotoxin protein (NSP4) for comparison of receptor directed and transduction peptide mediated antigen targeting to the gut-associated lymphoid tissues for enhanced protection against rotavirus infection. Oral immunization with Tat-NSP4[subscript]90 fusion protein isolated from Escherichia coli generated detectable anti-NSP4[subscript]90 IgG titers in mice."
"CTB-NSP4[subscript]90 fusion protein stimulated higher serum IgG titers than CTB fused to a 22-aa immunodominant epitope NSP4[subscript]22 indicating the presence of additional immunogenic epitopes in the NSP4[subscript]90 peptide," reported Tae-Geum Kim and colleagues at Loma Linda University. "Mice immunized with CTB-NSP4[subscript]22 stimulated high IgG2a antibody levels suggesting a dominant Th1 lymphocyte response. However, mice immunized with CTB-NSP490 generated similar levels of IgG1 and ...
