The effect of Ad-hMPV-G expression on type I IFN induction. A549 cells were infected with Ad-hMPV-G or Ad-lac z (MOI 1). Cells were collected at the indicated times after infection for the quantification of IFN α/β mRNA transcription by RT-qPCR. hMPV G expression did not affect IFN-α or –β expression at 6 h or 12 h post-infection
