SLC35A2 and infection: To assess whether the observed non-overlapping functions of SLC35A1 and SLC35A2 were maintained during infection with other paramyxoviruses, we infected single and double KO A549 cells with the Respirovirus rSeVCeGFP, the Avulavirus rNDVeGFP, or the Rubulavirus MuV at an MOI of 1.5 and look for either GFP expression (SeV and NDV) or stained for MuV NP at 24 hpi.
