Researchers develop gene therapy to boost brain repair for demyelinating diseases
(Medical Xpress) -- Our bodies are full of tiny superheroesantibodies that fight foreign invaders, cells that regenerate, and structures that ensure our systems run smoothly. One such structure is myelina material that forms a protective, insulating cape around the axons of our nerve cells so that they can send signals quickly and efficiently. But myelin, and the specialized cells called oligodendrocytes that make it, become damaged in demyelinating diseases like multiple sclerosis (MS), leaving neurons without their myelin sheaths. As a consequence, the affected neurons can no longer communicate correctly and are prone to damage. Researchers from the California Institute of Technology (Caltech) now believe they have found a way to help the brain replace damaged oligodendrocytes and myelin.
