Infection and replication of EV71 in L929, L929-SCARB2KO, and L929-EXT1KO cells. A, B AF647 signals in different cells were detected at 20 or 100 min post-infection. Scale bar: 10 μm. C, D Densities of AF647 Fluorescent signals in ~ 20 L929, L929-SCARB2KO, and L929-EXT1KO cells at 20 or 100 min post-infection were quantified with the Fiji Image J software. *p < 0.05, ns: not significant. Viral RNA copy numbers (E) and Virus titers (F) were detected at the indicated time points. The time point when the incubation period (1 h) was over was set as timepoint zero
