Outline of Final Research Achievements

MOGAD (Myelin oligodendrocyte glycoprotein antibody-associated disease) is a disease concept established by the discovery of conformation sensitive MOG antibodies. The clinical phenotype is diverse, and the severity and response to treatment vary from case to case, but the factors underlying these differences are unknown. In this study, we found that selective intrathecal MOG antibodies are involved in the clinical phenotype of cortical encephalitis and acute disseminated encephalomyelitis, that intrathecal active complement is elevated in cases of severe MOGAD, and that the activity level of perivascular deposition of complement differs among individuals.

Academic Significance and Societal Importance of the Research Achievements

MOG抗体の存在は古くから知られていたものの、臨床的な意義が再発見されたのは比較的新しく、その根本的な病態が不明な点も多く残されている。特に、重症例や再発抑制困難例が時に認められるものの、その治療法が定まっていない。本研究では、その一端が活性補体に見出される可能性を発見した。これは、今後本疾患を治療する上で、大きな影響を与えうるものと考えられる。一方で、補体活性のレベルが症例毎に異なることも重要な発見であり、抗補体治療を一律に適応することは不適切であることも示唆している。
