Jean Dausset

Jean Dausset was a French immunologist known for his groundbreaking research in the field of genetics and immune response. He won the Nobel Prize in Physiology or Medicine in 1980 for his discovery of human leukocyte antigens (HLA). These molecules are crucial for the immune system, helping the body distinguish between its own cells and foreign invaders like viruses and bacteria. Dausset's work significantly advanced our understanding of tissue compatibility, which is essential for organ transplants and treatments for autoimmune diseases. His contributions have had a lasting impact on medicine and immunology.
