There is no change in IL-25 and thymic stromal lymphopoietin (TSLP) production in the intestines of infected mice. Female IL-33^−/− and WT BALB/c mice (3 animals per group) were subcutaneously infected with 50 S. mansoni cercariae for 9 weeks and sacrificed at 6 and 9 wpi. Small intestines were homogenized with the gentleMACS Octo Dissociator and the cytokines were measured in the homogenate supernatants by ELISA. a IL-25 from infected and non-infected mice. b TSLP from infected and non-infected mice. Experiments were replicated twice with similar results. Data are presented as the mean with SEM. Mouse genotypes were compared using the Mann–Whitney test for non-infected mice and the unpaired two-tailed t-test with Welch’s correction for infected mice
