Inhibition of human xenogenic or allogenic antibodies to reduce xenograft or allograft rejection in human recipients

摘要

Reactivity between an alloantigen and an anti-alloantigen is indicative of immunological reactivity between two biological samples of the same species. Reactivity between a xenoantigen and an anti-xenoantigen is indicative of immunological reactivity between two biological samples of different species. In many cases both of the reactions are indicative of an antibody-mediated rejection. Anti-antibodies can be employed to reduce cross-reactivity in many transplantation-type situations, either within a similar species, or across species lines. These anti-antibodies are prepared against the antibodies responsible for the antibody-mediated rejection. These anti-antibodies can then be used in vivo or in vitro to complex with the antibodies thus reducing or eliminating reactivity between an alloantigen and an anti-alloantigen or reactivity between a xenoantigen and an anti-xenoantigen between any two species combinations. These antibodies may also be used to target and eliminate the B-cells that produce anti-xenogenic antibodies.
