Cytokine. Inhibits inflammatory cytokine production. Synergizes with IL2 in regulating interferon-gamma synthesis. May be critical in regulating inflammatory and immune responses. Defects in IL13 may be a cause of susceptibility to allergic rhinitis (ALRH). Allergic rhinitis is a common disease of complex inheritance and is characterized by mucosal inflammation caused by allergen exposure. Belongs to the IL-4/IL-13 family.
