Fig. 6From: Inhibition of influenza virus via a sesquiterpene fraction isolated from Laggera pterodonta by targeting the NF-κB and p38 pathwaysInhibition of influenza virus-induced signalling pathway by fr14. A549 cells were washed with PBS and subsequently incubated with virus A/PR/8/34 (MOI = 0.1) diluted in PBS for 30 min at 37 °C. Then, the inoculums were aspirated, and the cells were incubated with MEM in the absence and presence of different concentrations (150, 100, 50 μg/ml) of fr 14 for 24 h at 37 °C. Cell lysis and western blots were performedBack to article page
