Myelin-associated inhibitors are proteins found in the central nervous system that play a role in preventing nerve regeneration after injury. They are part of the myelin sheath, which insulates nerve fibers and helps transmit electrical signals efficiently. When nerves are damaged, these inhibitors can hinder the growth of new nerve connections, making recovery more difficult. These inhibitors include proteins such as Nogo-A, OMgp, and MAG. Research into myelin-associated inhibitors aims to understand their mechanisms and find ways to block their effects, potentially leading to improved treatments for conditions like spinal cord injuries and multiple sclerosis.
