    GlossaryHuman Leukocyte Antigen

    group of proteins on cell surfaces aiding immune recognition

    Human Leukocyte Antigen (HLA) refers to a group of proteins found on the surface of most cells in the body. These proteins play a crucial role in the immune system by helping it distinguish between the body's own cells and foreign invaders, such as viruses and bacteria. HLA typing is important in organ transplantation to ensure compatibility between donors and recipients, reducing the risk of rejection.
