Figure 5. Effect of RSV-infected HBECs on concentrations of IL-4, IFN-γ and IL-17 secreted by lymphocytes (pg/mL, n = 10/group, mean±SEM; *P<0.05 vs. L ^▵P<0.05 vs. RL ^▴P<0.05 vs. HL.

The levels of IL-4, IL-17 and IFN-γ in group HRL were highest in four groups. The level of IFN-γ in group HL was higher than those of groups L and RL.
