Fig 1. IL-1β and OPN mRNA expression in RSV infected cells.

HEp-2 and HEK-293 cells were mock infected or infected with 1 MOI of RSV-L19F. RNA was isolated at 24, 48 and 72 hpi. (A-C) Expression levels of RSV-N, IL-1β and OPN were determined by qPCR. Results are presented as fold-change in expression of RSV-N, IL-1β or OPN mRNA normalized to the control (HPRT). qPCR data are represented as means ±SEM. Experiments were performed in triplicate. ** p < 0.01, *** p < 0.001**** p < 0.0001.
