| Outline of Final Research Achievements |
Erythropoietin (EPO), which is a therapeutic drug for anemia, has recently been known to have a neuroprotective effect, but the mechanism is unknown. In many brain diseases, microglia, which are one of the cells constituting the brain, are often activated. We focused on activated microglia, which damage the brain, and found that microglia have a receptor for EPO.
In this study, experiments were carried out using microglia culture cells and mice, and the neuroprotective effect of EPO was achieved by inhibiting the activity of microglia in the brain, such as inflammatory cytokine production and damaging phagocytosis. EPO may be useful as a therapeutic drug in acute brain diseases in the area of emergency and intensive care.

| Academic Significance and Societal Importance of the Research Achievements |
貧血の治療薬であるエリスロポエチンの脳神経保護作用の機序の一部を明らかにしたことで、救急・集中治療領域の急性期脳疾患に対するエリスロポエチン治療の適応が明らかになる。そして、エリスロポエチン治療を実際に行うことで急性期の脳障害を最小限にし、意識障害の改善、死亡率の改善、脳後遺症の軽減などが期待できるかもしれない。
