| Summary: | Until recently, all in vitro drug susceptibility assays of cytomegalovirus (CMV) were performed in clinically irrelevant fibroblast cells. This study sought to test if drug susceptibility was affected by cell type. MRC-5 embryonic lung fibroblasts and ARPE-19 retinal pigmented epithelial cells were infected with BADrUL131-Y4 epithelial/fibroblast tropic virus under serial concentrations of ganciclovir (GCV) or maribavir (MBV). Virus was quantified using plaque reduction, GFP fluorescence, and yield reduction. Both drugs performed less efficiently in ARPE-19 cells. A cell type effect was observed for both plaque reduction and yield reduction assays with implications for the treatment of CMV retinitis as well as other manifestations of CMV Disease that involve non-fibroblast cell types. |
