Graft Rejection Can Be Reduced By

Question

Graft rejection can be reduced by
A) preventing B cell activation.
B) antiphagocytic factors.
C) antihistimines.
D) preventing T cell proliferation.
E) epinephrine.

Accepted Answer

Graft rejection is mainly caused by T cells recognizing foreign antigens on the transplanted tissue and attacking it. Therefore, preventing T cell proliferation (such as with immunosuppressive drugs) is the most effective way to reduce graft rejection. Preventing B cell activation, antiphagocytic factors, antihistamines, and epinephrine do not directly target the underlying mechanism of T cell-mediated graft rejection.
