Outline of Final Research Achievements

The purpose of this recent research is to clarify the pathological mechanism of the cochlea and vestibular symptom accompanied with fibromyalgia. We had investigated the clinical symptom like tinnitus, deafness, vertigo and dizziness those accompanied with the patient with fibromyalgia.
Then, our recent study aimed the analysis of the molecular mechanism through the experiment used cultural inner ear cells. Especially, we had cleared the parts of the mechanism of apoptosis and necroptosis among the cultural inner ear cells utilizing the endoplastic reticulum stress induced by added tunicamycin exposure. Then we suggested the possibility of the distant miRNA propagation of the pathological information from those inner ear cells towards the distant organs using exosomes transportation.

Academic Significance and Societal Importance of the Research Achievements

線維筋痛症は近年着目されてきた疾患で全身の筋痛のみならず多様な症状を呈する。しかしその病態メカニズムには未解明な部分も多く、それゆえに確実な治療法もいまだ模索されている状況である。本研究で我々は線維筋痛症における蝸牛・前庭症状に対して分子生物学的に病態へのアプローチをおこない、小胞体ストレスを受けた際の内耳培養細胞ならびにエクソソームの動向における新たな知見を得てきた。この研究成果はのちの線維筋痛症の諸症状への解明につながるとともに新たな根本的な治療薬の開発につながる可能性をもち斬新なものである。
