Key Concepts

Immunosuppressive Drugs

Immunosuppressive drugs are medications used to deliberately reduce or suppress the recipient's immune system to prevent it from attacking the transplanted organ. Their use is critical in the management of transplant patients as it helps prevent rejection and ensures the longevity of the graft.

MHC Tissue Antigens

MHC tissue antigens (also known as human leukocyte antigens or HLA in humans) are vital for immune recognition. Matching these antigens between the donor and the recipient minimizes immune system discrepancies, reducing the chance of organ rejection and enhancing the likelihood of a successful transplant.

ABO Blood Group Antigens

ABO blood group antigens are specific protein markers on the surface of red blood cells that play a crucial role in blood transfusion and organ transplantation. Matching these antigens between donor and recipient reduces the risk of rejection and other immune complications, thereby increasing transplant success.
