Interleukin (Il)-18 Promotes the Development of Chronic Gastrointestinal Helminth Infection by Downregulating IL-13

Abstract

Expulsion of the gastrointestinal nematode Trichuris muris is mediated by a T helper (Th) 2 type response involving interleukin (IL)-4 and IL-13. Here we show that Th1 response-associated susceptibility involves prior activation of IL-18 and caspase-1 followed by IL-12 and interferon (IFN)-gamma in the intestine. IL-18-deficient mice are highly resistant to… (More)
