immune system
increased T cell proliferation ( J:153235 )
• peripheral T cells proliferation is increased in the absence of stimulation due to homeostatic expansion compared to in wild-type mice
abnormal T cell differentiation ( J:153235 )
• differentiation of double positive T cells in the thymus is inhibited compared to in wild-type mice
• however, mice exhibit normal beta selection, negative selection, peripheral activation, and homeostatic proliferation
decreased CD4-positive, alpha-beta T cell number ( J:153235 )
• CD4+ T cells are decreased in the thymus as early as in neonates but mildly in the periphery compared to in wild-type mice
• CD4+ T cells are decreased in the spleen and lymph nodes compared to in wild-type mice
decreased CD8-positive, alpha-beta T cell number ( J:153235 )
• CD8+ T cells are decreased in the thymus as early as in neonates but mildly in the periphery compared to in wild-type mice
• CD8+ T cells are decreased in the spleen and lymph nodes compared to in wild-type mice
increased memory T cell number ( J:153235 )
• mice exhibit an increase in the number of memory/activated CD4+ T cells compared with wild-type mice
