Each stage of schistosome in human body can cause disease. Pathogenic factors released by the parasites induce host immune responses and cause a series of immunopathological changes. As a major cell population in in- nate immunity, macrophages are important in the initiation and development of schistosomiasis. This paper summarizes the activation and polarization of macrophages, and the role of macrophages in schistosome immunopathology and immune evasion.
