Interleukin-25-mediated resistance against intestinal trematodes does not depend on the generation of Th2 responses

2020

AbstractInterleukin-25 (IL-25) is recognized as the most relevant initiator of protective Th2 responses in intestinal helminth infections. It is well known that IL-25 induces resistance against several species of intestinal helminths, including the trematode Echinostoma caproni. E. caproni has been extensively used as an experimental model to study the factors determining the resistance to intestinal infections. Herein, we assessed the role of IL-25 in the generation of resistance in mice to E. caproni infections. ICR mice are permissive hosts for E. caproni in which chronic infections are developed in relation to the lack of IL-25 production in response to primary infection and the consequ…

Treatment of mice with rIL-4 or rIL-13 induces a Th2 response and RELM-β overexpression in response to primary Echinostoma caproni and infection but not resistance to infection. (A) expression of cytokine mRNA in the intestinal tissue of rIL-4-treated or rIL-13-treated mice at 2 weeks post-primary infection with E. caproni; (B) expression of RELM-β mRNA in the intestinal tissue (F) of naïve mice, non-infected rIL-4- or rIL-13-treated mice and infected rIL-4- or rIL-13-treated mice at 2 weeks post-primary infection. The relative quantities (RQ) of cytokine genes are shown after normalization with β-actin and standardization of the relative amount against day 0 sam…
