Outline of Research at the Start

脳腫瘍に浸潤するマクロファージは、CD47-SIRPαによる免疫チェックポイントや免疫抑制性M2タイプへの分化により貪食能は低下し、腫瘍の進行・悪性化に寄与している。本研究では、髄芽腫脳移植マウスモデルに対してSIRPα抗体やSIRPα結合環状ペプチドを用いてCD47-SIRPαシグナルを抑制させ、インターフェロンγ(IFNγ) などを用いてマクロファージを免疫抑制性M2タイプから免疫促進性M1タイプへ分化誘導させることによりマクロファージの貪食能を亢進させ、抗腫瘍効果を促進するか否かを検討する。なり、臨床的意義は高いものと考える。

Outline of Final Research Achievements

Due to the difficulty of conducting analyses using medulloblastoma cell models, we investigated the relationship between macrophage function and epilepsy onset in glioblastoma. We analyzed the concentration of the macrophage-associated molecule sCD163 in the cerebrospinal fluid (CSF) of glioblastoma patients and examined the association between intratumoral metabolites and the presence or absence of seizures. CSF sCD163 levels showed a positive correlation with the number of CD163-positive M2 macrophages in tumor tissue, and both were significantly lower in the preoperative seizure group compared to the non-seizure group. Magnetic resonance spectroscopy revealed an inverse correlation between glutathione (GSH) concentration and the number of sCD163-positive M2 macrophages. Lower sCD163 levels were associated with a lower incidence of seizures. These findings suggest that CD163-expressing macrophages may suppress epileptic activity.

Academic Significance and Societal Importance of the Research Achievements

マクロファージのM2タイプは腫瘍免疫微小環境に強く作用し、抗炎症作用があると言われているが、神経の異常活動であるてんかんの発症を抑制している可能性が示唆された。マクロファージには様々なタイプがあり、腫瘍内でさまざまな機能を有しているが、M2マクロファージの作用を強化することで、脳腫瘍患者の生活の質を低下させるてんかんの発症を抑制させる可能性があり、社会的意義はあるものと思われる。
