Question

Quizplus · Accepted Answer

The Human Leukocyte Antigen (HLA) System is the human counterpart of the major histocompatibility complex. It refers to a group of genes that code for proteins on the cell surface that play a central role in the immune system's recognition of self from nonself. These proteins help the immune system to distinguish between foreign agents, such as bacteria or viruses, and healthy body cells. HLA genes are highly polymorphic, which means that there is a high degree of variability within the population. This is important for transplant medicine, as matching HLA types between a donor and recipient can help reduce the risk of transplant rejection.
