What is allograft rejection?
Allograft rejection is the consequence of the recipient’s alloimmune response to nonself antigens expressed by donor tissues. … In the direct pathway, recipient T cells react to intact allogeneic MHC molecules expressed on the surface of donor cells. This pathway would activate host CD4 or CD8 T cells.
