DSG2 and infection: Three days after infection, DSG2 protein levels were assessed by WB, confirming the expected reduction in DSG2 protein level, which was of similar extent in cells inoculated with either MOI 50 or 100 (85.1 ± 5.6 % reduction compared with controls, n = 3 independent experiments; p ≤ 0.01) (Figure 5a).
