Treatment with dynasore did not prevent the endocytosis of occludin (Figure 4E) or the decrease in TER caused by EPEC at 1–2 h post-infection (–15.0 ± 3.0% vs. –14.0 ± 2.0%; –36.0 ± 5.0% vs. –30.0 ± 2.0%, with and without dynasore at 1 and 2 h post-infection, respectively) (Figure 4F). Here, OCLN is linked to infection.
