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 Jun?n virus (JUNV) multiplication. We found that cholesterol cell depletion reduced JUNV glycoproteins (GPs) membrane expression and virus budding. Analysis of membrane protein insolubility in Triton X-100 suggested that JUNV GPs associate with cholesterol enriched membranes. Rafts dissociation conditions as warm detergent extraction and cholesterol removal by methyl-β-cyclodextrin compound showed to impair GPs cholesterol enriched membrane association. Analysis of GPs transfected cells showed similar results suggesting that membrane raft association is independent of other viral proteins. |
