Membrane localization of Junín virus glycoproteins requires cholesterol and cholesterol rich membranes
Arenavirus morphogenesis and budding occurs at cellular plasma membrane; however, the nature of membrane assembly sites remains poorly understood. In this study we examined the effect of different cholesterol-lowering agents on Junín virus (JUNV) multiplication. We found that cholesterol cell deplet...
