Medical researchers have used a bone marrow transplant to replace faulty immune system cells in models of Rett syndrome. The procedure arrested many severe symptoms of the childhood disorder, including abnormal breathing and movement, and extended the lifespan of Rett mouse models. Exploring the function of microglia deficient in the Rett protein scientists uncovered a completely novel approach to this devastating neurological syndrome.
