Genetic deficiencies of both IL-4 receptor alpha chain and IL-10 trigger early onset of severe colitis in mice
Inflammatory bowel diseases are associated with dysregulated inflammatory immune responses in the gastrointestinal tract. We found that deficiencies of both IL-4 receptor alpha chain (IL-4Rα) and IL-10 in BALB/c mice (IL-4Rα × IL-10 KO mice) highly induced spontaneous rectal prolapse and diarrhea. These mice also exhibited severe colitis in their cecum and colon and marked elevation of serum proinflammatory cytokines including TNFα and IFNγ. These pathologies were transmittable with their cecal contents containing Helicobacter spp. Their mesenteric LN cells produced TNFα and IFNγ in response to soluble H. hepaticus antigens and high titers of H. hepaticus-specific serum IgG were also detected. These results suggested the important function of IL-4Rα signaling in controlling the intestinal inflammation and the susceptibility to intestinal microbes including H. hepaticus. Therefore, these IL-4Rα × IL-10 KO mice potentially provide the significant murine model for clarifying the causes and control of spontaneous colitis and intestinal inflammation.

• Antigen receptor sites
• Autoimmunity
• Delayed-type hypersensitivity or cellular immunity
• Immunologic deficiency states and their reconstitution
• Immunologic surveillance and tumor immunity
• Immunomodulation
• Immunotherapy
• Lymphokines and cytokines
• Nonantibody immunity
• Parasite immunology
• Resistance to intracellular microbial and viral infection
• Thymus and lymphocyte immunobiology
• Transplantation immunology
• Tumor immunity.
