What Causes Kidney Transplant Rejection?

Rejection is usually due to the action of the immune system. The immune system is the body's defense mechanism against harmful foreign substances such as microbes, cancer cells, and toxins. You can find the best and right chronic renal failure treatment in South Texas to improve your health.

If the antigen of the donor’s kidney does not match the antigen of the recipient donor, the body's own immune system recognizes the kidney as foreign and sends antibodies to attack the "invasive kidney".

No human being has the exact same antigen as another person's antigen for identical twins. Antigens from people who are not identical twins can only be combined, but not the same. Therefore, the body always sends antibodies to attack the antigens in the transplanted kidney tissue, if the twins are not identical.

To counter the immune system's defense mechanisms against antigens in the transplanted kidney, doctors use drugs that are responsible for suppressing the immune system.
