In addition, flow cytometry analysis showed that WT and Park2−/− cells had similar susceptibility to VSV-GFP and HSV-1-GFP viral infection (Figure S1B) at various time points, which further suggests that Parkin does not affect the susceptibility of cells to initial viral infection or their ability to respond to viral infection by production of type I IFN. This evidence concerns the gene PRKN and viral infectious disease.
