Researchers have strived for years to determine how neurons are produced and integrated into the brain throughout adult life. In an intriguing twist, scientists reporting in the August 11 issue of the Cell Press journal Developmental Cell provide evidence that adult-born neurons are derived from a special type of circulating blood cell produced by the immune system. The findings—which were made in crayfish—suggest that the immune system may contribute to the development of the unknown role of certain brain diseases in the development of brain and other tissues.
