digestive/alimentary system
• less colon shortening
• decreased leukocyte infiltration
• less crypt loss
• reduced epithelial hyperplasia

immune system
• less colon shortening
• decreased leukocyte infiltration
• less crypt loss
• reduced epithelial hyperplasia
• 15 days after aerosol challenge with M. tuberculosis, mice produce less CD4+ T cells with an activated CD44hiCXCR3+ phenotype than wild-type
• following vaccination against M. tuberculosis, mice do not lower bacterial burden in the lung 30 days after challenge and fail to elicit an accelerated IFN-gamma or IL-17 T cell recall response
• low levels of IL22 after DSS treatment
• increase in levels after DSS treatment is less than for controls
• 15 days after aerosol challenge with M. tuberculosis, mice fail to produce mononuclear granulomatous structures as wild-type mice do
• following vaccination against M. tuberculosis, mice do not lower bacterial burden in the lung 30 days after challenge and fail to elicit an accelerated IFN-gamma or IL-17 T cell recall response

homeostasis/metabolism
• low levels of IL22 after DSS treatment
• increase in levels after DSS treatment is less than for controls
• significantly less weight loss after treatment with Sodium Dextran Sulfate (DSS) than in controls
