Most human tissue and organ transplants are allografts. Due to the genetic difference between the organ and the recipient, the recipient's immune system will identify the organ as foreign and attempt to destroy it, causing transplant rejection. The risk of transplant rejection can be estimated by measuring the panel-reactive antibody level.
Cytomegalovirus (CMV) is the most common opportunistic infection that may occur after a kidney and other solid organ transplants and is a risk factor for graft failure or acute rejection. [79] [81] BK virus is now being increasingly recognised as a transplant risk factor which may lead to kidney disease or transplant failure if untreated. [82]
The donor kidney is typically placed inferior of the normal anatomical location. Kidney transplantation is the organ transplant of a kidney in a patient with end-stage renal disease. Kidney transplantation is typically classified as deceased-donor (formerly known as cadaveric) or living-donor transplantation depending on the source of the ...
At 5 years post-transplant, 80% of lung transplants, 60% of heart transplants and 50% of kidney transplants are affected, while liver transplants are only affected 10% of the time. [20] Therefore, chronic rejection explains long-term morbidity in most lung-transplant recipients, [ 23 ] [ 24 ] the median survival roughly 4.7 years, about half ...
A beating heart awaiting transplant. American medical researcher Simon Flexner was one of the first people to mention the possibility of heart transplantation. In 1907, he wrote the paper "Tendencies in Pathology," in which he said that it would be possible one day by surgery to replace diseased human organs – including arteries, stomach, kidneys and heart.
Xenotransplantation (xenos-from the Greek meaning "foreign" or strange [1] [2]), or heterologous transplant, is the transplantation of living cells, tissues or organs from one species to another. [3] Such cells, tissues or organs are called xenografts or xenotransplants .

Graft-versus-host disease (GvHD) is a syndrome, characterized by inflammation in different organs. GvHD is commonly associated with bone marrow transplants and stem cell transplants. White blood cells of the donor's immune system which remain within the donated tissue (the graft) recognize the recipient (the host) as foreign (non-self). The ...
