WebMay 7, 2014 · Trypsin-induced cell-cell fusion mediated by overexpressed S proteins. To otherwise assess the role of R890 in trypsin-mediated S protein activation, we made use of a cell-cell fusion assay. As indicated in Fig. 1, continuous treatment of PEDV-infected cells with trypsin results in cell-cell fusion yielding syncytia.
