Transplantation Immunology

Transplantation is the process of moving cells, tissues, or organs from one place to another, either inside the same person or between a donor and a recipient. One that has failed or been harmed due to illness or injury may be replaced with healthy organ or tissue from a donor. Both cellular (mediated by lymphocytes) and humoral (mediated by antibodies) systems have a role in the immunological response to an organ transplant. The T cells have a key role in the rejection of grafts, despite the involvement of other cell types. The sensitization stage and the effector stage make up the rejection reaction.
