Outline of Final Research Achievements

The rat middle cerebral artery was transient occluded and stroke model was prepared. The subcutaneous administration of a mixture of IL-3 and GM-CSF from the next day reduced the brain tissue loss and improved cognitive dysfunction. The cytokine mixture increased Bcl-xL expression in neurons but reduce that in microglia. These results suggest that the cytokine mixture inhibited neuronal apoptotic changes, thereby preventing aggravating effects of activated microglia.

Academic Significance and Societal Importance of the Research Achievements

本研究は、脳梗塞後の虚血辺縁部の慢性的な神経細胞死の拡大を防ぐ方法を、サイトカイン投与という形で可能になることを明らかにし、現実的な治療法を提示したことになり、医学医療上の意義は大変大きい。また、脳梗塞後の亜急性期の神経細胞死の原因はよくわかっていなかったが、神経細胞障害が引き金となってマイクログリアの活性化が生じ、そのマイクログリアは抗アポトーシス因子 Bcl-xL発現によって防がれていることを示した意義も大きい。フローサイトメトリーにおいて、CD200をターゲットとして用いれば神経細胞を分離できることを明らかにした点は、今後の研究手法の発展につながる。
