Researchers remyelinate neurons
German neurogenetics at the Max-Planck-Institute for Experimental Medicine have cured the rare incurable hereditary Charcot-Marie-Tooth disease by simply supplementing the food of mice carrying the disease-causing duplication of the PMP22 gene with lecithin. The phospholipid supplementation enabled Schwann cells deficient in lipid synthesis to restore the insulating myelin sheet around peripheral neurons which is needed to speed up neuronal transmission.
