Keywordsコロナウイルス / オルガノイド / インフルエンザウイルス / 風邪コロナウイルス
Outline of Research at the Start

現在、ヒトの世界に存在する風邪コロナウイルスは4種類である。しかし、これらを効率よく分離培養できる細胞は存在しない。風邪コロナウイルスの増殖部位は、鼻腔などの上気道である。従って、ヒト鼻腔組織を再現できれば、すべての風邪コロナウイルスを効率よく分離培養できる系を確立できると予想される。そこで本研究では、ES細胞を分化誘導することでヒト鼻腔オルガノイドを作出し、さらに2次元のシート状に培養することで、風邪コロナウイルスの新たな分離培養法を開発することを目的とする。

Outline of Final Research Achievements

Efficient culturing of human coronaviruses poses a challenge due to the absence of cell lines capable of culturing all four types. Here, we aimed to establish human nasal organoids as a platform for studying these viruses. Initially, we established 2D nasal organoids as a novel culture system of human coronaviruses. Using this system, we demonstrated that 229E, OC43, and NL63 viruses replicated as effectively, if not more so, in nasal organoids compared to conventional cultured cell lines. Notably, HKU1 virus, which failed to replicate in conventional cultured cell lines, showed successful replication in nasal organoids. These results indicate the potential of our 2D nasal organoids as a novel culture system for human coronaviruses.

Academic Significance and Societal Importance of the Research Achievements

ウイルス培養については、HCoV-229EはHela-ACE2-TMPRSS2細胞で、HCoV-NL63はLLC-MK2細胞で、HVoV-OC43の実験室株はHRT-18細胞で増殖可能であることが報告されているが、すべての風邪コロナウイルスの増殖をサポートする細胞はない。さらにHCoV-HKU1は培養できる細胞株が存在しない。本研究によりヒトに感染する全てのコロナウイルス(SARS-CoV-2含む)が増殖可能な培養系を確立できたことは、コロナウイルスの基礎研究を進展させるだけでなく、地方衛生研究所等における疫学調査の強化にも大きく貢献すると考えられる。
