The mechanism of action of micafungin against pteropine orthoreovirus infection in the human A549 cell line.

ABSTRACT: Pteropine orthoreovirus (PRV) is a fusogenic virus carried by bats that causes respiratory illnesses in humans. Micafungin (MCFG), an approved drug for treatment of fungal infections, has been shown to inhibit the propagation of PRV, but its precise mechanism of action remains unclear. In this study, we investigated the molecular mechanism of action of MCFG against PRV propagation. A molecular docking simulation showed that the p17 protein of PRV is likely to be the primary target of MCFG. Differential gene expression analysis was performed to compare MCFG-treated PRV-infected host cells with untreated infected cells, and IL-6 was found to be the main regulator induced by MCFG. Silencing of IL-6 using siRNA resulted in markedly increased levels of PRV release and syncytium formation and ma
