A protein activated by vitamin D could be involved in repairing damage to myelin in people with multiple sclerosis (MS), according to new research from the University of Cambridge. The study, published today in the Journal of Cell Biology, offers significant evidence that vitamin D could be a possible treatment for MS in the future.
Researchers, from the MS Society Cambridge Centre for Myelin Repair, identified that the ‘vitamin D receptor’ protein pairs with an existing protein, called the RXR gamma receptor, already known to be involved in the repair of myelin, the protective sheath surrounding nerve fibres.
By adding vitamin D to brain stem cells where the proteins were present, they found the production rate of oligodendrocytes (myelin making cells) increased by 80%. When they blocked the vitamin D receptor to stop it from working, the RXR gamma protein alone was unable to stimulate the production of oligodendrocytes.
