Outline of Research at the Start

現在、感染症治療の主体は抗菌薬や抗ウイルス薬などにより担われているが、これらの薬剤はそれぞれ標的微生物が限定的であるため、新興・再興感染症への対応は困難であった。一方、免疫機能を人為的に賦活化する「宿主志向型治療」が提唱されているが、炎症惹起による副作用が問題となっている。申請者は最近、獲得免疫の中核を担うはずのCD4 T細胞中に、自然免疫的感染防御機能を有する新規「MP細胞」を同定した。そこで本研究ではMP細胞の特性や感染防御機能、炎症惹起能の全容を解明することにより、副作用を最小化しつつあらゆる病原体に幅広く対応し得る新規「免疫賦活化治療」を創出することを目標とする。

Outline of Final Research Achievements

CD4 T lymphocytes play an essential role in adaptive immunity. Within this population, we reported a novel “memory-phenotype” (MP) cell subpopulation that possesses innate immune function in pathogen infection. Based on this finding, we aimed to identify phenotypic markers of MP cells and reveal their immunological significance in host defense as well as autoimmunity. In this study, we found that CD127, Sca1, and Bcl2 are differentially expressed by MP vs. foreign antigen-specific memory cells and that MP cells themselves can be divided into four subpopulations depending on the marker expression. Furthermore, we defined innate immune function as well as autoimmune activities of the CD127(hi) Sca1(hi) MP subset (Front Immunol 2022). Together these results suggest CD127(hi) Sca1(hi) MP cells as a potential therapeutic target in infectious disease by deliberately activating their innate immune activities.

Academic Significance and Societal Importance of the Research Achievements

本研究により、MP細胞がCD127、Sca1発現により4分画に分類されること、うちCD127(hi) Sca1(hi) MP分画が最も強い自然免疫活性ならびに自己免疫活性を有することが明らかになった。今後、同分画の活性化機構や免疫学的機能の全容が明らかになれば、MP細胞を人為的に活性化することによる新たな感染症治療戦略「免疫賦活化治療」(JMA J 2022)の創出、抑制による新たな自己免疫・炎症性疾患治療法の提唱などにつながり得るものと期待される。
