immune system
• nave CD4+ T cells stimulated in vitro through the TCR only have a third the proliferative response as control mice
• 66% fewer naive CD4+ T cells go into S-phase with 24 hours of TCR stimulation compared to controls
• the S-phase entry defect can be partly overcome by CD28 stimulation
• allogeneic proliferative response of nave CD4+ T cells is reduced 6-fold compared to controls
• the amount of IL-2 required for a half maximal proliferation response is 100-fold higher than in controls
• CD4+ memory T cells are reduced by 3-fold in the spleen
• splenic CD8+ memory T cells are also reduced
• reconstitution of wild-type mice with both wild-type and mutant bone marrow demonstrate an intrinsic defect of mutant hematopoietic cells to produce CD4+ memory T cells
• there is a 75% decrease in the number of regulatory T cells found in the spleen, lymph node and thymus of mice
• reconstitution of wild-type mice with both wild-type and mutant bone marrow demonstrate an intrinsic defect of mutant hematopoietic cells to produce CD4+ regulatory T cells
• nave CD4+ T cells only produce one-third the amount of IL-2 as controls after in vitro stimulation
• most mice have small or absent inguinal lymph nodes
