digestive/alimentary system
• expression analysis indicates enhanced differentiation and increased numbers of goblet cells
• increased proliferation of intestinal stem cells in the colon and in culture
• increased expression of tight junction proteins
• intestinal epithelial barrier integrity degradation in response to DSS is reduced at 2.5 days post treatment as determined by increased leakage of FITC-dextran into the blood stream in wild-type mice but not mutants
• reduced endocytosis of Occludin in TNF-treated cells in culture
• show milder symptoms (decreased weight loss, decreased Disease Activity Index, longer colons, reduced histological colon damage) following dextran sodium sulfate (DSS)-induced colitis
• no differences in body weight or colon length are seen in the absence of DSS treatment

immune system
• show milder symptoms (decreased weight loss, decreased Disease Activity Index, longer colons, reduced histological colon damage) following dextran sodium sulfate (DSS)-induced colitis
• no differences in body weight or colon length are seen in the absence of DSS treatment
• decrease in DSS-stimulated expression of Il1b and Il6
• cultured bone marrow derived macrophages show reduced Il1b and Il6 expression after LPS and Ifng treatment

homeostasis/metabolism
• intestinal epithelial barrier integrity degradation in response to DSS is reduced at 2.5 days post treatment as determined by increased leakage of FITC-dextran into the blood stream in wild-type mice but not mutants

endocrine/exocrine glands
• expression analysis indicates enhanced differentiation and increased numbers of goblet cells

cellular
• expression analysis indicates enhanced differentiation and increased numbers of goblet cells

hematopoietic system
• decrease in DSS-stimulated expression of Il1b and Il6
• cultured bone marrow derived macrophages show reduced Il1b and Il6 expression after LPS and Ifng treatment
