hematopoietic system
• thymocytes show a 50% reduction in frequency of apoptosis compared to wild-type littermates
• 2-fold increase in frequency of apoptosis in spleen is detected
• enlargement is more moderate compared to homozygotes
• thymic weight is increased by 30% compared to wild-type littermates
• slight reduction in frequency of CD44-expressing cells is observed, suggesting a deficit in memory T cell development
• a 50% reduction in cells memory cells (showing high CD44 expression) is observed in spleen, compared to controls
