• mice exhibit normal numbers of neutrophil, eosinophil, basophil, macrophage, and neutrophil numbers, and normal antigen-specific T cell proliferation, T-dependent and T-independent antibody responses, and cytotoxic T lymphocyte (CTL) activity
• T cells exhibit defective cell cycle progression unlike in wild-type mice
• blocked at the CD4-CD8- double negative stage and CD4+CD8+ double-positive stage
• reduced CD3+, CD4+ and CD8+ T cells
• in an in vivo assay
• however, NK cells treated with phorbol myristate acetate (PMA)/ionomycin exhibit normal degranulation, granzyme B release, and tumor necrosis factor and IFN-gamma production
• in response to homeostatic expansion signals after transfer into irradiated wild-type mice, CD4+ T cells fail to proliferate and undergo apoptosis unlike wild-type mice
