Outline of Final Research Achievements |
The novel coronavirus pandemic has caused social stagnation and threatened the lives of the public. In this research project, I attempted to elucidate the innate immune recognition mechanism of novel coronaviruses and the innate immune evasion mechanism of novel coronaviruses. As a result, I found that novel coronaviruses are recognized by RIG-I-like receptors. Furthermore, I found that an accessory protein encoded in the novel coronavirus gene suppresses the innate immunity of the host.

Academic Significance and Societal Importance of the Research Achievements |
本研究ではRIG-IとMDA5の両方が新型コロナウイルスゲノムを認識し得ることを示した。その一方で、新型コロナウイルスのゲノム由来の蛋白質は強力に宿主のインターフェロン産生を抑制していることも発見した。このようなウイルスの生存戦略を明らかにすることは、新型コロナウイルス患者の免疫応答の理解や治療戦略を策定する上で重要な知見となることから意義深いと考える。
