Outline of Final Research Achievements

It is known that a patient having impaired glucose tolerance develops a decrease the ability for protecting infection due to leukocyte dysfunction. In recent years, the relationship between endoplasmic reticulum stress and glucose homeostasis has been suggested, so we have focused on macrophages, which play an important role in controlling infection. The present study revealed that induction of endoplasmic reticulum stress contributes to macrophage dysfunction through the CHOP pathway under septic hyperglycemic stress.

Academic Significance and Societal Importance of the Research Achievements

敗血症高血糖ストレス病態は集中治療および周術期に遭遇する頻度が高く、それらの病態は易感染性から手術創部感染を引き起こすことが問題である。本研究では、その易感染性メカニズムの一因が、CHOP経路を介した小胞体ストレスの誘導がトリガーとなっておこるマクロファージの機能障害の可能性があることを明らかにしたことに学術的意義があると考えている。そして、これらのメカニズムをターゲットとした治療に展開する可能性を秘めていることに社会的意義があると考えられる。
