HLA (Human leukocyte antigen)

Human leukocyte antigen (HLA) refers to a group of proteins on the surface of most cells in the body, crucial for the immune system's ability to recognize self from non-self. HLA helps the immune system identify which cells belong to the body and which are invaders, such as bacteria or viruses. Each person has a unique HLA profile, influencing their response to diseases, effectiveness of organ transplants, and susceptibility to certain autoimmune conditions. Understanding HLA is vital in fields like transplantation and immunology, as it helps ensure compatibility and manage immune responses effectively.

    Human Leukocyte Antigens (HLA) are proteins found on the surface of cells that help the immune system identify which cells belong to the body and which are foreign, like viruses or bacteria. Each person has a unique set of HLA markers inherited from their parents. These markers play a crucial role in organ transplantation, as a close match between donor and recipient HLA profiles reduces the risk of rejection. HLA is also significant in autoimmune diseases and the body’s response to infections, making it an essential aspect of immunology and overall health.
