Outline of Final Research Achievements

Infectious diseases caused by arboviruses (viruses transmitted by blood-sucking arthropods and can also grow in the arthropods), such as dengue fever and SFTS, have become a severe problem on public health worldwide. A common feature of arboviruses is that they can grow in both vertebrates and arthropods. In this study, we compared host factor networks between vertebrates and arthropods, and extracted a homologous core network. We then identified several host factors that are likely to be associated with arbovirus replication in cells.

Academic Significance and Societal Importance of the Research Achievements

アルボウイルス(蚊やマダニなどの吸血性節足動物によって媒介されるウイルスのうち、節足動物体内でも増殖するウイルス)は、吸血に乗じて感染を繰り返すために、脊椎動物と節足動物という大きくことなる環境を往復することに特化しているウイルスである。そのため、他のウイルスと異なり、脊椎動物と節足動物の両方に保存されている因子を利用して増殖できると考えられる。本研究では、そうした因子を明らかにし、アルボウイルス感染症に対する治療薬の開発などに役立つ成果を得た。
