AIM To explore the therapeutic effect of fasudil and its possible mechanisms in experimental autoimmune encephalomyelitis(EAE) mice. METHODS Female C57BL/6 mice were immunized with MOG_(35-55) peptides to establish chronic EAE model. These mice were randomly divided into early treatment group in which fasudil 40 mg·kg~(-1)·d~(-1) was injected intraperitoneally on day 3 post- immunization, late treatment group in which fasudil was injected in a similar manner at onset of symptoms and EAE control group.
