Multiple Sclerosis Could Be Treated With a Surprise Medication

An already approved medication used for bladder problems might help to treat multiple sclerosis, according to researchers at the State University of New York at Buffalo.
Lead author Fraser J. Sim, PhD, Assistant Professor in the Department of Pharmacology and Toxicology in the University at Buffalo School of Medicine and Biomedical Sciences stated “We have identified a new drug target that promotes stem cell therapy for myelin-based disease, such as MS.”
The research appeared in the Journal of Neuroscience and was funded by the National Multiple Sclerosis Society, the Kalec Multiple Sclerosis Foundation and the Empire State Stem Cell Fund.
The medication is called solifenacin, which has already been approved by the federal drug administration (FDA) to treat overactive bladder. The drug targets a receptor for the neurotransmitter acetylcholine, known as the muscarinic receptor. It could also act on cells that remyelinate the nerves of the body. Myelin is the fatty substance that wraps around neurons and is damaged in multiple sclerosis due to an autoimmune attack. Oligodendocytes are specialized cells that produce the myelin.
“Our hypothesis is that in MS, the oligodendrocyte progenitor cells seem to get stuck,” Sim noted. “When these cells don’t mature properly, they don’t differentiate into myelinating oligodendrocytes.”
In the study, Sim and his coworkers studied the molecular pathways that control how oligodendrocyte cells formed. Then they tried to identify drugs that could change how much myelin the oligodendrocytes produce.
