immune system
increased T cell apoptosis ( J:141917 )
• the rate of T cells undergoing apoptosis in culture is slightly greater than in wild-type and Nfatc3tm1Grc/Nfatc3tm1Grc Tg(Lck-cre)I57Jxm mice
• however, the number of T cells initially undergoing apoptosis is normal
abnormal T cell differentiation ( J:141917 )
• T cell development is partially blocked after pre-TCR signaling and the DN4 population is reduced compared to in wild-type mice but is not more severe than in Nfatc3tm1Grc/Nfatc3tm1Grc Tg(Lck-cre)I57Jxm mice
abnormal double-negative T cell morphology ( J:141917 )
• mice exhibit an increase in DN1 and subsequently a more severe decrease in the number of DN4 T cells compared to in wild-type, Nfactc3 null or Nfact2 null mice
