The four main types of tissue transplantation are xenotransplantation, allotransplantation, isotransplantation and autotransplantation, while the common tissues transplanted include skin, bone, corneal and vessel grafts. [3] Tissue transplantation comes with risks and complications, including immune rejection and viral infections.
[2] [19] Adults are significantly likely to suffer from hyperacute rejection, [1] thrombosis, or death, but could be considered to be an acceptable risk if the alternative is death. [6] In the case of ABOi renal transplantation, aggressive antibody removal is required, along with supplemental medication, with the resulting condition being ...
Acute rejection is a category of rejection that occurs on the timescale of weeks to months, with most episodes occurring within the first 3 months to 1 year after transplantation. [ 6 ] [ 8 ] Unlike hyperacute rejection, acute rejection is thought to arise from two distinct immunological mechanisms as lymphocytes , a subset of white blood cells ...
As with many operations, allotransplantation risks some side effects. A limiting factor in tissue allotransplantation for reconstructive surgery deals with the side effects of immunosuppression (metabolic disorders, malignancies, opportunistic infections) which is a predominant issue. The risk of transmitting infection is high.
The Banff Foundation for Allograft Pathology also known as the Banff Foundation for Transplant Pathology is a nonprofit Swiss foundation which aims to "lead development and dissemination of the international Banff Classification of Allograft Pathology and to facilitate multidisciplinary, collaborative research to enhance its scientific basis and clinical utility to improve the care of ...
Rejection mediated by T lymphocytes sensitized by direct allorecognition pathway is predominant in the short period after the transplantation, but usually subsides with depletion of passenger cells while indirect recognition contributes to continuing graft damage and plays role in chronic rejection.
The Immunologic Constant of Rejection (ICR), is a notion introduced by biologists to group a shared set of genes expressed in tissue destructive-pathogenic conditions like cancer and infection, along a diverse set of physiological circumstances of tissue damage or organ failure, including autoimmune disease or allograft rejection.

The first short-term success in human hand transplant surgery occurred with Clint Hallam, [4] from New Zealand. Hallam lost his hand in an accident while in prison. [5] [6] [7] The operation was performed on September 23, 1998, [8] in Lyon, France, by a team assembled from different countries around the world led by French Professor Jean-Michel Dubernard, including Professor Nadey Hakim, from ...
