The Enigma of Autoimmunity | For decades, scientists believed T cells were key defenders against infections and cancers. However, it remained unclear how the immune system could attack invaders without harming the body itself. While central tolerance in the thymus—the organ behind the breastbone—was known to train T cells to distinguish self from non-self, it did not explain why autoimmune diseases could still develop later in life. T cells originate in the bone marrow and travel to the thymus to mature, learning to differentiate between self and foreign cells. Yet, some harmful T cells seemed to escape this process, and the mechanism for controlling them remained unknown. (Image: Canva)
