• despite the reduction in T cell differentiation in the thymus, the numbers and ratios of CD4+ or CD8+ T cells in the spleen and lymph nodes, VDJ rearrangement, and the numbers and function of NK cells are normal
decreased T cell proliferation ( J:15579 )
• intraepithelial lymphocytes fail to proliferate in response to stimulation with anti-CD3 antibodies and ConA unlike heterozygous cells
decreased splenocyte proliferation ( J:15579 )
