Outline of Research at the Start

ヒトに病原性があるISKウイルスと病原性がないと考えられるSTBウイルスについて、本研究ではその病原性の発現機序と、更に2ウイルス間にある増殖性や病原性の相違の機序を明らかにすることを主目的とする。ISKウイルスおよびSTBウイルスを含めKeterah orthonairovirusの生物学的あるいはウイルス学的解析に取り組んでいる研究者は国内外を通し我々のグループのみであり、本研究なくしてはKeterah orthonairovirusの学術研究は進まない。

Outline of Final Research Achievements

We compared virological characteristics of two orthonairoviruses, Issyk-Kul virus which causes Issyk-Kul disease, and soft tick bunyavirus which was found in Japan and is similar with Issyk-Kul virus.
Followings were revealed; no apparent growth difference in 8 mammalian cell lines, partial cross-reactivities of anti-sera, no apparent pathogenicity difference in IFNAR1-KO mice, and monoclonal antibodies to the viral envelope and Avigan were effective in treatment in mouse model.
These findings support further therapeutic development against Issyk-Kul and related diseases because therapeutic candidates were found, whereas we could not exclude a possibility that soft tick bunyavirus in Japan causes a disease in humans.

Academic Significance and Societal Importance of the Research Achievements

日本で発見されたsoft tick bnyavirusとIssyk-Kul熱をおこすIssyk-Kulウイルスはウイルス学的に非常に似ていた。Issyk-Kul熱は日本で発生しておらず、不明熱の原因としてsoft tick bnyavirusが少ないながらある可能性が考えられた。単クローン抗体やインフルエンザ薬のアビガンがマウスモデルで治療効果を示したことから、これらの開発を進めることでsoft tick bnyavirus(や関連ウイルス)による感染症あるいはIssyk-Kul熱の国内侵淫に備えることができる。
