Mechanism of action

BIIB122 blocks LINGO-1 (leucine-rich repeat and Ig domain-containing nogo receptor-interacting protein), which is a negative regulator of oligodendrocyte differentiation and myelin formation. By inhibiting LINGO-1, the drug aims to promote remyelination and restore neurological function in demyelinating diseases. This mechanism is intended to support repair and regeneration of damaged myelin in conditions like multiple sclerosis.
