Histocompatibility
Histocompatibility
Histocompatibility (pronounced: his-toh-kom-pat-uh-bil-uh-tee) is a term used in immunology to describe the compatibility between the tissues of different individuals, which is determined by the similarity of their antigens, specifically the Major Histocompatibility Complex (MHC).
Etymology
The term "histocompatibility" is derived from the Greek words "histo" meaning tissue, and "compatibility", which refers to the ability of two things to exist or work together without conflict.
Definition
Histocompatibility is a crucial factor in successful organ transplantation. It refers to the degree of similarity between the alleles of the MHC in the donor and recipient. The greater the similarity, the less likely it is that the recipient's immune system will recognize the transplanted tissue as foreign and mount an immune response against it.
