Fig 2. Effect of PMA or PMA+EGTA on virus entry.

Fully polarized Caco-2 cells were treated apically with PMA only or with PMA and then EGTA before infection with (A) HAZV or (B) CCHFV at MOI 1. Data show the relative variation of viral RNA in comparison to control (mock). Bars represent mean ±SD based on three independent experiments.
