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]

Even though a record 41,000 organ transplants were conducted in the U.S. last year, more than 100,000 Americans are estimated to be on the transplant waiting list. An average of 17 people die each ...
Organ trade (also known as the blood market or the red market) is the trading of human organs, tissues, or other body products, usually for transplantation. [1] [2] According to the World Health Organization (WHO), organ trade is a commercial transplantation where there is a profit, or transplantations that occur outside of national medical systems.
While lung transplants carry certain associated risks, they can also extend life expectancy and enhance the quality of life for end-stage pulmonary patients. While the precise details of surgery will depend on the exact type of transplant, there are many steps which are common to all of these procedures.
If the organ donor is human, most countries require that the donor be legally dead for consideration of organ transplantation (e.g. cardiac death or brain death). For some organs, a living donor can be the source of the organ. For example, living donors can donate one kidney or part of their liver to a well-matched recipient. [2]
Xenotransplantation is a cross-species tissue transplantation from animal to human. [10] [11] The development of blood vessel anastomosis opened the door for xenotransplantation during the 20th century, which led to numerous attempts in organ transplantations with tissues from nonhuman primates (NHPs).
