| Research Abstract |
The disease becomes severe in individuals who possess anti-AQP4 antibodies, together with anti-myelin oligodendrocyte glycoprotein (MOG) antibodies. In optic neuritis models, visual acuity decreases first, infiltration of microglia andinflammatory cells. Thereafter, the number of axons decreases and latency of visually evoked potential (VEP) is prolonged. Applying this phenomenon, cell therapy using dendritic cells transfected with CGRP or dendritic cells transfected with IL-10 was attempted, and was found to be effective in suppressing optic neuritis. At the same time, as a more practical therapy, administration of the new multiple sclerosis drug fingolimodsuggests suppression of cell infiltration into the optic nerve.
