Comparison study on clinical and neuropathological characteristics of hamsters inoculated with scrapie strain 263K in different challenging pathways.

Objective: To understand the infectious characteristics of a hamster-adapted scrapie strain 263K with five different routes of infection including intracerebral (i.c.), intraperitoneal (i.

Coupling of antigen to cholera toxin for dendritic cell vaccination promotes the induction of MHC class I-restricted cytotoxic T cells and the rejection of a cognate antigen-expressing model tumor.

We previously demonstrated that cholera toxin (CT) is highly efficient as a combined carrier and adjuvant for dendritic cell (DC) vaccination, inducing strong Th1-dominated B cell and CD4(+) T cell responses. In this study we show that vaccination with DC pre-pulsed ex vivo with CT-conjugated OVA (OVA-CT) gives rise to OVA-specific CD8(+) T cells that produce IFN-gamma and are cytotoxic for OVA-expressing E.G7 tumor cells both in vitro and in vivo.

A mucosally administered recombinant fusion protein vaccine against schistosomiasis protecting against immunopathology and infection.

We have constructed and efficiently produced and purified a candidate vaccine against schistosomiasis consisting of a novel hybrid protein in which two dominant T- and B-cell epitopes from Schistosoma mansoni 28 kDa glutathione-S-transferase (Sm28GST) antigen (a.a 24-43 and 191-212) are fused to cholera toxin B subunit (CTB). Intranasal treatment of S.
