Research Abstract

It was known that B cells played an important role as well as T cells for acute and chronic rejection. We sensitized B cells in the patients of blood type incompatibility liver transplantation and the bone marrow transplantation, with a donor antigen using humanized-NOG mouse in ex-vivo and evaluated donor antibody production ability. As a result, it was shown that reactive B-cell clones were removed at the stage when immature B cells matured by the antigens in the organ and induced the tolerance. The suppression of the chronic rejection, the possibility that, besides, tolerance was obtained for T-cell immunity were demonstrated by B-cell removal.
