T49 |
0-121 |
Sentence |
denotes |
To further assess the effect of GA on plaque formation, we used the CMVPT30-GFP strain, which produces cell-free virions. |
T50 |
122-279 |
Sentence |
denotes |
HFF monolayers in 24-well plates pretreated with GA (1–20 µM) for 1 h were inoculated with 50–100 plaque-forming units of CMVPT30-GFP per well.16, (Fig. 1B). |
T51 |
280-356 |
Sentence |
denotes |
The number of plaques were counted after 7 days and the IC50 was determined. |
T52 |
357-457 |
Sentence |
denotes |
As predicted by the previously-determined IC50, at 5 and at 10 µM the antiviral effect was apparent. |
T53 |
458-575 |
Sentence |
denotes |
Furthermore, at 10 µM, only single cells were infected, indicating that there was no cell-to-cell virus transmission. |
T54 |
576-687 |
Sentence |
denotes |
These results may be explained as inhibition of secondary infections or that viral entry may be a target of GA. |
T55 |
688-882 |
Sentence |
denotes |
To verify these results, we compared the inhibition of infection by GA using a plaque reduction assay (PRA) similar to the PRA for ganciclovir (GCV), the preferred antiviral HCMV drug of choice. |
T56 |
883-1107 |
Sentence |
denotes |
The results showed that although there was strong inhibition of the virus at 16 µM GCV, there were still visible plaques (>5 adjacent cells showing HCMV cytopathic effect) indicating cell-to-cell transmission of the virions. |
T57 |
1108-1309 |
Sentence |
denotes |
On the contrary, CMVPT30-GFP infected monolayers that were treated with 10 µM GA only displayed individual infected cells in intact HFF monolayers, (Fig. 1C), thus indicating no cell-cell transmission. |
T58 |
1310-1347 |
Sentence |
denotes |
We also tested GA C17:1 and GA C13:0. |
T59 |
1348-1455 |
Sentence |
denotes |
Both GA compounds had a strong inhibitory effect on HCMV infection by PRA, similar to GA C15:1 (Fig. 1D,E). |
T60 |
1456-1547 |
Sentence |
denotes |
None of the GA structures showed cytotoxicity at their active concentrations, respectively. |
