The complete inhibition of infection in the presence of 10% autologous serum or UV-irradiation was further confirmed by the complete absence of IFN-β and IL-6 production by RSV exposed A549 cells, which depends for epithelial cell lines on the access of viral RNA to intra-cellular RLR (Figure 1A) [34,35]. The gene discussed is IFNB1; the disease is infection.
