Abstract

Immune responsiveness to schistosomal worm antigen was investigated in the individuals infected with Schistosoma japonicum by measuring the antigen-specific proliferative response of the peripheral T lymphocytes in vitro. Out of 57 infected individuals, 10 (17.5%) were low responders, whereas 47 (82.5%) were high responders to this antigen. The strong association between the HLA-Aw24-Bw52-DwI2 haplotype and the low responder group was demonstrated. Because the association of the low responder group was strongest with the HLA-D specificity, Dw12, and because the HLA-D region was assumed to be comparable to the I region of the murine H-2 complex, it was suggested that the low responsiveness to schistosomal worm antigen was controlled by a single dominant imune suppresssion gene that was in strong linkage disequilibrium with HLA-Dw12.
