immune system
• a 25% reduction in proliferation of both DN4 and DP thymocytes
• 50% reduction in total thymocyte numbers
• decrease in the number and percentage of DN4 cells and an increase in the DN3:DN4 ratio
• while the total number is reduced the percentage of DN cells is increased
• decrease in the number of CD4+ thymocytes
• however, the number of peripheral CD4+ lymph node T cells is not decreased
• decrease in the number of CD8+ thymocytes
• however, the number of peripheral CD8+ lymph node T cells is not decreased
