Dendritic cells act as the major antigen presenting cells in the body and play a central role in intriguing the adaptive immune response. Protective immunity against schistosome and immuno-pathological response in host caused by eggs are both closely associated with Th2 response. Further understanding on immune mechanism will contribute to the development of vaccines against schistosome infection, as well as the relief of the pathological lesion in schistosomiasis. This article discusses the central role of dendritic cells in the mechanism of Th2 response induced by schistosome (including eggs).
