Outline of Final Research Achievements

Schizophrenia (SCZ) affects approximately 1% of the population, and although prognosis is improved by pharmacotherapy and psychotherapy, the disease remains poorly understood. The applicant aims to understand the pathogenesis of SCZ by focusing on exosomes (EXO) in peripheral blood and analyzing microRNAs (miRNAs) in EXO. EXO is involved in intercellular communication and crosses the blood-brain barrier, which may reflect neuropsychiatric disorders. In this study, EXO of neural origin was extracted and analyzed for miRNA changes. The results showed a trend toward a decrease in miR-675-3p in the SCZ group, but the difference was not significant. In the future, we will proceed with analysis of treatment-resistant SCZ and comprehensive analysis of multiple miRNAs to develop new therapeutic targets.

Academic Significance and Societal Importance of the Research Achievements

この研究は、統合失調症(SCZ)の病態解明における新たなアプローチを提示する点で学術的に非常に意義がある。特に、末梢血から神経細胞由来のエクソソーム(EXO)を抽出し、その中のmicroRNA(miRNA)を解析することで、SCZに関連する分子生物学的変化を高精度で捉えることを目指している。この手法は、従来の対症療法的アプローチを超え、SCZの病因や病態の理解を深める可能性がある。特に治療抵抗性SCZに焦点を当てた研究は前例が少なく、この分野における新たな知見を提供する可能性が高い。また、抗精神病薬がEXO miRNAの発現に及ぼす影響を検討することで、薬物治療のメカニズム解明にも貢献する。
