immune system
• with mononuclear cell infiltration of the colon seen at 4 - 6 months of age
• in older mice numbers of activated/memory T cells increases; however, these cells contain only unrecombined alleles
• markedly reduced numbers of peripheral T cells
• at 4 - 6 months of age almost no naive T cells are found in the spleen and lymph nodes
• severe decrease in the number of CD24low mature cells while the number of CD24high immature cells is similar to controls
• severe decrease in the number of CD24low mature cells while the number of CD24high immature cells is similar to controls
• no detectable regulatory T cells in the thymus or spleen at 6 weeks of age
• decreased numbers of single positive T cells, especially CD8+ cells, while the numbers of double negative and double positive T cells is similar to controls
• seen at 4 - 6 months of age
• increase in the numbers of myeloid lineage cells (macrophages, neutrophils) but almost a complete absence of naive T cells is detected at 4 - 6 months of age
• dose-dependent induction of cell death in response to TNF stimulation unlike controls cells which are viable after TNF stimulation
• impaired proliferation in response to anti-CD3 stimulation with or without co-stimulation by anti-CD28
• seen at 4 - 6 months of age

digestive/alimentary system
• at 4 - 6 months of age, loss of goblet cells is seen in the large intestine but not in the small intestine
• prominent ulceration is seen at 4 - 6 months of age in the large, but not the small, intestine
• stiff colon present at 4 - 6 months of age
• seen at 4 - 6 months of age
• severe diarrhea beginning at 4 - 6 months of age
• with mononuclear cell infiltration of the colon seen at 4 - 6 months of age

growth/size/body
• begins at 4 - 6 months of age
• seen at 4 - 6 months of age
• increase in the numbers of myeloid lineage cells (macrophages, neutrophils) but almost a complete absence of naive T cells is detected at 4 - 6 months of age

hematopoietic system
