초록

Nocardiopis sp. 유래의 protein kinase 저해제인 KT5720, KT5926을 사용하여 Vesicular Stomatitis Virus (VSV) 증식에 미치는 세포변성의 억제를 지표로서 연구하였다. 그 결과 CAMP의존 kinase를 저해하는 KT5720, mysion light chain kinase (MLCK)를 저해하는 KT5926이 VSV에 의한 세포변성을 억제시켰다. Protein kinase inhibitor KT5720은 VSV의 증식에 영향을 미치지는 않지만, 세포변성과정은 억제하는 것으로 나타났다. Virus RNA 및 단백질 합성에서 PKA KT5720이 영향을 미치지 않는 것은 virus 증식에 영향이 없는 것으로 나타난다. Virus 증식과정에서 성질이 다른 protein kinase가 관여하는데, 이것은 negative strand virus에 대한 항virus 제 개발에 중요한 역할을 한다고 생각한다.

I investigated the effect of KT5720, an inhibitor of protein kinase A, on the vesicular stomatitis virus (VSV) infection in BHK-21cell cultures. The virus inducted cytopathic effect (CPE) was almost completely suppressed by KT5720 at 5uM. The inhibitor, however, did not affect replication of the virus nor the synthesis of viral macromolecules. KT5720, did not block the cytoskeletal disruption, while the cell rounding was suppressed. And, the KT5720-sensitive function may be involved in developing the VSV-induced CPE, but not essential for the virus replications.
