immune system
increased T cell apoptosis ( J:187325 )
• in CD8+ T cells following IL2 withdrawal
decreased T cell proliferation ( J:187325 )
• induced by cytokines or LCMV
• however, proliferation induced by anti-CD3 and anti-CD28 is almost normal
abnormal leukocyte morphology ( J:187325 )
• slight increase in splenic B to T cell ratio compared to in control mice
• however, total numbers are normal
abnormal T cell subpopulation ratio ( J:187325 )
• the ratio of CD4 to CD8 is modestly increased compared to in control mice
abnormal regulatory T cell physiology ( J:187325 )
• T regulatory cells transferred into Rag2 null mice exhibit increased colitis compared with mice receiving wild-type cells
