Interleukin 1 β (IL-1B) and IL-1 antagonist receptor (IL-1RN) gene polymorphisms are associated with the genetic susceptibility and steroid dependence in patients with ulcerative colitis.

Abstract excerpt

BACKGROUND: Ulcerative colitis (UC) is an inflammatory bowel disease of unknown etiology. Among cytokines induced in UC, interleukin 1 antagonist (IL-1ra) and interleukin 1 β (IL-1β) seems to have a central role because of its immunoregulatory and proinflammatory activities. GOAL: To determine the association between IL-1RA and IL-1B gene polymorphisms and the clinical features of UC in the Mexican Mestizo...
