The tissue antigens most involved in graft rejection involve
A)Rh.
B)ABO.
C)MHC.
D)MLB.

Question

Quizplus · Accepted Answer

The major histocompatibility complex (MHC) is the most involved tissue antigen in graft rejection. This complex is a cluster of genes that code for proteins that play a key role in the immune response, specifically in recognizing foreign substances and presenting them to T cells. The presence of mismatched MHC antigens between the donor and recipient is the primary trigger for rejection in organ transplantation. Rh and ABO blood group antigens can also play a role in rejection, but to a lesser extent than MHC antigens. MLB is not a tissue antigen involved in graft rejection.
