Stimulation of IFN signalling with UIFN in PaKiT03 cells. a Quantitation of the number of nuclei per syncytium in UIFN treated and mock PaKiT03 cells. b Visualisation by immunofluorescence microscopy of PaKiT03 cells treated with UIFN and mock following NBV infection at 24 and 40 hpi (DAPI in blue and NBV σ proteins in green). Representative pictures are shown here. **p < 0.01, ***p < 0.001, ns = non-significant c NBV titre at 24 and 40 hpi following 3 h simulation with UIFN of PaKiT03 cells prior to virus infection
