HLA

HLA, or Human Leukocyte Antigen, refers to a group of genes found on your cells that help your immune system distinguish between your body's own cells and foreign invaders like germs or transplanted tissues. These genes produce proteins on the surface of cells that act as markers, signaling whether a cell belongs to you or is foreign. Proper HLA matching is essential for successful organ transplants and understanding immune responses. Variations in HLA genes among individuals influence susceptibility to certain diseases and the body's ability to accept or reject transplants.
