N normal phenotype
homeostasis/metabolism
abnormal circulating interleukin level ( J:216867 )
• low levels of IL22 after DSS treatment
increased circulating interleukin-17 level ( J:216867 )
• increase in levels after DSS treatment is less than for controls
decreased physiological sensitivity to xenobiotic ( J:216867 )
• significantly less weight loss after treatment with Sodium Dextran Sulfate (DSS) than in controls

immune system
decreased susceptibility to induced colitis ( J:216867 )
• less colon shortening
• decreased leukocyte infiltration
• less crypt loss
• reduced epithelial hyperplasia

growth/size/body
weight loss ( J:216867 )
• 15% weight loss after treatment with 2.5% Sodium Dextran Sulfate (DSS) for 5 days
• fail to recover until 10 days after treatment
• IL22 treatment protects against weight loss

digestive/alimentary system
abnormal large intestine crypts of Lieberkuhn morphology ( J:216867 )
• increased crypt loss and epithelial damage after treatment with 2.5% DSS for 5 days
• IL22 treatment protects against crypt loss
decreased colon length ( J:216867 )
• short colon after treatment with 2.5% DSS for 5 days
• IL22 treatment protects against colon shortening

immune system
abnormal circulating interleukin level ( J:216867 )
• reduced expression of IL22 after DSS treatment
decreased interleukin-17 secretion ( J:216867 )
• reduced expression after DSS treatment

homeostasis/metabolism
abnormal circulating interleukin level ( J:216867 )
• reduced expression of IL22 after DSS treatment

endocrine/exocrine glands
abnormal large intestine crypts of Lieberkuhn morphology ( J:216867 )
• increased crypt loss and epithelial damage after treatment with 2.5% DSS for 5 days
• IL22 treatment protects against crypt loss
