Outline of Final Research Achievements

Glial inflammation is a common characteristic in neuroinflammation in neurodegenerative diseases such as Parkinson’s disease and Alzheimer’s disease. We investigated the role of short- and medium-chain fatty acids in glial inflammatory responses. We found that short- or medium-chain fatty acids inhibited microglial inflammatory responses such as NO, ROS production and phagocytotic activity. The results obtained potentiate the possibility that short- and medium-chain fatty acids are effective therapeutic drug for neurodegenerative diseases.

Academic Significance and Societal Importance of the Research Achievements

神経炎症反応が進むことにより神経変性疾患の病態が増悪・進行することから、これを抑える方法の開発は喫緊の課題である。本課題では短鎖および中鎖脂肪酸が中枢グリア細胞の炎症反応を抑制し神経炎症を軽減可能なことを明らかにした。短鎖および中鎖脂肪酸は食を介して摂取可能であり、既存の治療薬と比較して副作用も少ないと考えられる。神経変性疾患の治療に対する短鎖および中鎖脂肪酸の新たな可能性を提示した。
