Figure 4: (a) Phase contrast, immunostaining for RSV/G-protein and claudin-4, and freeze-fracture image in human nasal epithelial cells in vitro (hTERT-HNECs) at 24 h after infection with RSV. Scale bars: white bars = 20 μm, black bars = 100 nm. (b) Transepithelial electrical resistance (TER) values in hTERT-HNECs at 24 h after infection with RSV. , * versus control.
