Outline of Final Research Achievements |
Rhinovirus is the causative agent of respiratory tract infections. However, there have been a few cases where rhinoviruses were detected in patients with non-respiratory tract symptoms (nRTS), such as myocarditis and encephalitis. In this study, we performed a genetic analysis of rhinoviruses detected in patients with nRTS. The results showed that the serotype A105 was detected exclusively in patients with nRTS. Three patients with serotype A105 were admitted to different hospitals in various months, suggesting that a specific serotype might be involved in the pathogenesis of rhinovirus-induced nRTS.

Academic Significance and Societal Importance of the Research Achievements |
一般的な風邪の原因ウイルスであるライノウイルスが、下気道感染症のみならず、脳炎や心筋炎・心膜炎を呈した重症患者から検出されている。しかし呼吸器症状以外の患者症状に焦点を当てたライノウイルス感染症の研究は非常に限られており、その病原性発現機序はほとんど不明である。そのような背景の中、本研究では非呼吸器症状を示した患者より検出されたライノウイルスの解析を行い、特定の血清型が非呼吸器症状の発現に関与する可能性を示唆した。本研究は未だ不明な点が多く残るライノウイルスの病原性発現機序の解明に貢献するものである。
