Outline of Final Research Achievements

Cerebral brain edema is an important complication of traumatic brain injury (TBI). Glial activation, namely astrocyte swelling is responsible for the edema. We investigated the effect of inflammasome on the activation of glial cells such as microglia and astrocytes and its role in TBI. We found that the activation of inflammasome augmented inflammatory responses such as nitric oxide (NO) and reactive oxygen species (ROS) production and IL-1 bete excretion after TBI and that pre-treatment of acetate or lauric acid reduced these responses. The results obtained potentiate the possibility that short- and medium-chain fatty acids are effective therapeutic drug for brain edema after TBI.

Academic Significance and Societal Importance of the Research Achievements

TBI後みられる脳浮腫に対する治療薬の開発は喫緊の課題である。TBI後の脳浮腫にはインフラマソームの活性化が関与することを新たに見出した。さらにこの活性化を抑制することにより、TBI後にみられる種々の炎症性反応が抑えられ浮腫を軽減出来ることを明らかにした。この作用をもつ候補として、食を介して摂取可能な短鎖および中鎖脂肪酸の可能性を提示した。
