Figure 7. SPS inhibited HSV-1 infection by blocking viral absorption. HCE-T cells were incubated with HSV-1g for 2 h at 4°C, and different concentrations of SPS were then added during absorption (A) and penetration (B). GFP fluorescence during absorption (C) and penetration (D) was detected using an inverted fluorescence microscope. The average fluorescence intensity was measured using ImageJ software. The average intensity of the control cells was assigned a value of 100. Data are presented as means ± standard deviations (n = 3). **p < .01 compared with the control group. *p < .05 compared with the control group.
