Rett Syndrome Breakthrough: How MIT Researchers Linked MicroRNA to Leaky Brain Vessels (2026)

A groundbreaking discovery by MIT researchers has shed light on the complex nature of Rett syndrome, a severe developmental disorder. The study, published in Molecular Psychiatry, reveals a molecular chain reaction triggered by two common genetic mutations associated with Rett syndrome. This chain reaction compromises the structural integrity of developing brain blood vessels, leading to a concerning phenomenon known as "leaky brain vessels."
