mortality/aging
• mice begin to die at 6 months of age due to wasting and diarrhea

immune system
• T cells Th1, Th2 and CTL (cytotoxic T lymphocyte) differentiation is enhanced while Th17-cell differentiation is inhibited
• in the experimental autoimmune encephalomyelitis model, the number of IL-17 producing T cells is reduced in animals that do and those that do not develop encephalomyelitis
• as determined by transplantation experiments, defects in Th17 cell differentiation occur in an autocrine manner
• T cell activation is enhanced
• following activation, interferon-gamma levels are increased relative to in control cells
• in the experimental autoimmune encephalomyelitis model, only mice that develop encephalomyelitis produce great amounts of interferon-gamma
• following activation, IL-4 levels are increased whereas IL-17 levels are decreased relative to in control cells
• 6 of 8 mice did not develop encephalomyelitis and only 2 showed mild disease compared to controls which all develop severe disease
• the number of IL-17 producing T cells is reduced in animals that do and those that do not develop encephalomyelitis
• only mice that develop encephalomyelitis produce great amounts of interferon-gamma
• mice present with mononuclear infiltrate in the lungs, parenchyma of the liver, and colon
• severe colitis is associated with disruption of the crypt architecture, crypt abscess formation and epithelium hyperplasia

digestive/alimentary system
• epithelium hyperplasia is associated with colitis
• disruption of crypt architecture is associated with colitis
• associated with colitis
• at 4 to 12 months of age, heavy mononuclear cell infiltrate of the lamina propria and subglandular areas of the colon is detected
• at 4 months of age
• severe colitis is associated with disruption of the crypt architecture, crypt abscess formation and epithelium hyperplasia

growth/size/body
• at 4 months of age mice display signs of wasting

liver/biliary system
• mononuclear cell clusters are detected in the parenchyma of mice with colitis

renal/urinary system
• IgG deposits accumulate in the glomeruli

respiratory system
• mononuclear cell infiltrate is present in the lungs of mice with colitis

endocrine/exocrine glands
• disruption of crypt architecture is associated with colitis
• associated with colitis

hematopoietic system
• T cells Th1, Th2 and CTL (cytotoxic T lymphocyte) differentiation is enhanced while Th17-cell differentiation is inhibited
• in the experimental autoimmune encephalomyelitis model, the number of IL-17 producing T cells is reduced in animals that do and those that do not develop encephalomyelitis
• as determined by transplantation experiments, defects in Th17 cell differentiation occur in an autocrine manner
• T cell activation is enhanced

homeostasis/metabolism
• following activation, interferon-gamma levels are increased relative to in control cells
• in the experimental autoimmune encephalomyelitis model, only mice that develop encephalomyelitis produce great amounts of interferon-gamma
• following activation, IL-4 levels are increased whereas IL-17 levels are decreased relative to in control cells
