immune system
decreased CD8-positive, alpha-beta T cell number ( J:189838 )
• 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
abnormal memory T cell physiology ( J:189838 )
• following infection with actA- L. monocytogenes-expressing ovalbumin, memory CD8+ T cells exhibit impaired maturation, function and recall response compared with control mice
decreased tumor necrosis factor secretion ( J:189838 )
• from CD8+ effector T cells following infection with actA- L. monocytogenes-expressing ovalbumin

hematopoietic system
