However, our understanding of the host factors involved in the processes of virus-cell and cell-to-cell fusion that occur during infection are limited to the described role of 25HC in interfering with NiV induced cell-to-cell fusion [46], and a the role of soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) protein USE1 in the glycosylation and expression of MuV fusion protein [47]. Here, USE1 is linked to infection.
