Fig. 2From: Respiratory syncytial virus prolifically infects N2a neuronal cells, leading to TLR4 and nucleolin protein modulations and RSV F protein co-localization with TLR4 and nucleolinNucleic changes in N2a and HEp-2 cells were observed by laser confocal microscopy using DAPI staining. a Nuclei of normal N2a cells; b nuclei of RSV-infected N2a cells at 4 d pi; c nuclei of normal HEp-2 cells; d nuclei of RSV-infected HEp-2 cells at 16 h piBack to article page
