HLA genes (Human Leukocyte Antigen)

HLA genes, or Human Leukocyte Antigens, are a group of genes that produce proteins on the surface of our cells. These proteins help the immune system distinguish between the body's own cells and foreign invaders like bacteria and viruses. They play a crucial role in immune responses and are important for tissue compatibility, especially in organ transplants. Variations in HLA genes are common and influence how individuals respond to infections and autoimmune diseases. Essentially, HLA genes are vital for immune system function and personal identity, ensuring our bodies recognize what belongs and what doesn't.
