CCL5 and infection: Cells were cultured and infected with Ad5F11bSP-Rantes, Ad5F11bSP-DsRed, Ad5SP-EGFP and Ad5-EGFP at MOI = 5 pfu/cell, and the viral titers were measured by the TCID50 method at 0 h, 48 h and 96 h after infection, and the replication folds at 48 h and 96 h were normalized to that at 0 h.
