AI: Scientists from Columbia University have discovered that the brain plays an important role in controlling the immune system. In a study in mice, they found that the brain can detect inflammation and modulate the immune response, boosting or suppressing it as needed. This discovery could lead to the development of new treatments for immune-related diseases such as rheumatoid arthritis, multiple sclerosis and inflammatory bowel disease. In addition, it may help create new approaches to treat acute inflammatory conditions, such as severe immune reactions due to viral infections.
