EIF2A and infection: To investigate whether the eIF-2α dephosphorylation inhibitor salubirinal affected the replication of RSV, expression of tight junction proteins, and production of the epithelial cell responses, HNECs were pretreated with 0.1–50 μg/ml salubrinal 30 min before infection with RSV at an MOI of 1 for 24 h.
