Skewed V beta TCR repertoire of CD8+ T cells in murine Trypanosoma cruzi infection.

abstract：:Based on the evidence that CD8+ cytotoxic T cells (CTL) precursors do not appear to distinguish between virus-infected cells and viral peptide-pulsed syngeneic cells, we have developed methods for priming class I MHC molecule restricted CD8+ CTL with such peptides without using any adjuvant. We were able to prime in v...
