Outline of Final Research Achievements

Patients with motor impairment occasionally have swallowing dysfunction. Synuclin is a protein which is related to motor impairment diseases including Parkinson’s disease. In this study, we examined the distribution of alpha-synuclein nerve fibers in the pharynx. We also examined the alpha-syunclein were contained in small- to medium-sized neurons in the vagus and glossopharyngeal ganglia.

Academic Significance and Societal Importance of the Research Achievements

筋萎縮症にかかわらず、嚥下障害が発生すると、生活の質の著しい低下が起こると考えられる。しかしながら、現状では、嚥下障害を完全に戻す方法は確立されていない。
本研究では、咽頭周囲においてalpha-synucleinを含む神経線維の分布を明らかにすることができた。さらなる応用研究が進むことで、新たな嚥下障害の治療法の確立につながる可能性があるため、本研究成果は社会的意義が高いと考えれれる。
