HSP90 ATPase activity is required for PDCoV infection.A, schematic of infection and inhibitor treatment time course. Blue double-headed arrows indicate the presence of HSP90 inhibitors, and red double-headed arrows indicate the incubation with PDCoV. PDCoV M mRNA levels in PDCoV-infected LLC-PK cells treated with (B) 17-AAG, (E) VER-82576, and (H) KW-2478. Viral titer in the supernatants from PDCoV-infected cells treated with (C) 17-AAG, (F) VER-82576, and (I) KW-2478. Western blots of PDCoV N protein from PDCoV-infected cells treated with (D) 17-AAG, (G) VER-82576, and (J) KW-2478. HSP90, heat shock protein 90; PDCoV, porcine deltacoronavirus.
