GA inhibits non-enveloped human adenovirus. (A) Monolayers of Vero cells were incubated for 1 hour with medium containing 10 µM GA C15:1 or DMSO vehicle. The cells were infected with GFP-HSV-1 virus at an MOI of 0.5 in medium containing 10 µM GA C15:1 for 24 hours. Infection was evaluated by light (lower panels) and fluorescence (upper panels) microscopy. (B) Monolayers of Vero cells were incubated for 1 hour with medium containing 10 µM of GA C15:1 or DMSO vehicle. The cells were inoculated with a replication-defective human adenovirus type 5 (dE1/E3) containing GFP (Ad-GFP) at an MOI of 0.5 in a medium containing 10 µM GA C15:1 for 24 hours. Inhibition of entry was evaluated by light (lower panels) and fluorescence (upper panels) microscopy.
