| Outline of Final Research Achievements |
Multiple sclerosis is a disorder that autoreactive lymphocytes invade into central nervous system (CNS) and destroy it. The inhibition of disruption of the CNS barriers (which allows the lymphocytes invade into the CNS) is an important therapeutic strategy. However, it remained to be elucidated for the molecular mechanism of CNS barrier breakdown. The present study was the first to clarify that “claudin-11” contributes to the tight junction formation of several CNS barriers and its down-regulation causes the breakdown of CNS barriers in multiple sclerosis.
