immune system
• thymi of mutant mice contain 10-fold fewer cells than do wild type thymi
• developing CD4+ T cells in the thymi of mutant mice have reduced expression of the T cell receptor (TCR) component CD3epsilon
• developing CD8+ T cells in the thymi of mutant mice have reduced expression of the T cell receptor (TCR) component CD3epsilon
• homozygous mutant mice have reduced numbers of CD4+ T cells in the periphery
• homozygous mutant mice have reduced numbers of CD8+ T cells in the periphery
• mutant mice previously immunized with irradiated, adenovirus transformed, syngeneic class I MHC deficient cells exhibit a reduced ability to kill an antigen specific, CD8+ cytotoxic T lymphocyte (CTL) target population (syngeneic splenocytes externally loaded with adenovirus E1B protein)
