IL7 and schistosomiasis: Of note, neither the morphology of liver macrophages (Figure S2) nor the development and fecundity of parasites (Figure S3) was significantly affected when mice were injected with IL‐7, anti‐IL‐7 neutralizing antibody or anti‐CD127 blocking antibody 3 weeks after S. japonicum infection, indicating that IL‐7 signalling contributes to the liver pathology in schistosomiasis via regulation of host immune responses instead of affecting the development and fecundity of parasites per se.
