hematopoietic system
• lymph node T cells respond almost normally to plate-bound anti-CD3 and anti-CD28 but are deficient in response to anti-CD3 and PMA or anti-CD3 and calcium ionophore
• unlike wildtype lymph node T cells or heterozygous thymocytes heterozygous lymph node T cells proliferate in response to PMA alone
• partial block of thymocytes development at the CD25+CD44- stage of development just prior to proliferation
• T cell levels in spleen only 20% of normal levels at 3 to 4 weeks of age
• CD4+ spleen and lymph node T cells increase with age to wild-type levels but CD8+ remain at low levels
• decrease in total thymocyte number
