• decreased CD8+ effector T cells in the peripheral blood lymphocytes compared with control mice and more so than in Tcf7tm1Cle homozygotes following infection with actA- L. monocytogenes-expressing ovalbumin
• decreased memory precursors and memory CD8+ T cells compared with control mice and more so than in Tcf7tm1Cle homozygotes following infection with actA- L. monocytogenes-expressing ovalbumin
• following infection with actA- L. monocytogenes-expressing ovalbumin, memory CD8+ T cells exhibit impaired maturation, function and recall response compared with control mice

immune system
• mutants infected with lymphocytic choriomeningitis virus (LCMV) to induce T-cell activation and thus cre-expression exhibit better survival of effector CD8 T cells under serum-starvation conditions compared to controls, but only show modest effects on the expansion and contraction of effector CD8 T cells
• clonal burst of mutant effector CD8 T cells is about 1/2 that of wild-type controls and there is a slight, but not significant reduction in the number of memory T cells that form in lymphoid and nonlymphoid tissues
• production of IL-2 by CD8 T cells is diminished in mutants infected with LCMV to induce T-cell activation and thus cre-expression
