Outline of Final Research Achievements

Whether microglia which activated in the spinal cord lesions of multiple sclerosis model mice are neuroprotective or neurotoxic is controversial. We have reviewed the gene expression pattern of microglia and discovered that these activated microglia expressed neuroprotective factors. In this study, we aimed to develop new treatment for the chronic phase of multiple sclerosis which there are currently no treatment options by amplifying neuroprotective effect of microglia. In the previous gene expression analysis, expression of EDNRB was up-regulated in activated microglia. It was able to reduce the severity of the disease by the administration of the selective antagonist of EDNRB, BQ788. Therefore, BQ788 was expected as a new therapeutic agents to treat chronic phase of multiple sclerosis.
