hematopoietic system
• increase of single positive thymocytes, evident at 2 weeks of age and preceding the onset of inflammatory bowel disease
• 3- to 5-fold increased proliferative response to T cell receptor stimuli
• 20-fold increase in the number of granulocytes in spleens and peripheral blood
• elevated in the large intestine, and more modestly in the small intestine
• correlative to increases observed in patients with inflammatory bowel disease
• elevated in the large, but not small, intestine
• correlative to increases observed in patients with inflammatory bowel disease

immune system
• increase of single positive thymocytes, evident at 2 weeks of age and preceding the onset of inflammatory bowel disease
• 3- to 5-fold increased proliferative response to T cell receptor stimuli
• 20-fold increase in the number of granulocytes in spleens and peripheral blood
• elevated in the large intestine, and more modestly in the small intestine
• correlative to increases observed in patients with inflammatory bowel disease
• elevated in the large, but not small, intestine
• correlative to increases observed in patients with inflammatory bowel disease
• elevated cytokine levels produced by both thymocytes and peripheral T cells, indicating that mature thymocytes migrate properly to spleen and lymph nodes and retain a hyper-responsive cytokine production profile

endocrine/exocrine glands
• increase of single positive thymocytes, evident at 2 weeks of age and preceding the onset of inflammatory bowel disease
• 3- to 5-fold increased proliferative response to T cell receptor stimuli
