title: Genetic control of immune responses to Schistosoma japonicum.
abstract: The mouse IgE antibody response to S. japonicum antigen (Sj) was found to be under control of a gene(s) linked to the major histocompatibility complex. In some strains but not all among low responders, however, T cell responsiveness to Sj could be demonstrated by the induction of carrier effect as well as by proliferation response. Resistance to reinfection with a large dose of S. japonicum cercariae was demonstrated in most strains examined, except C57BL/6, irrespective of the immune responsiveness. Further studies will be needed to elucidate whether genetically regulated immune responses may affect susceptibility to or pathogenesis of schistosomiasis japonica in the mouse.
