BST2/Tetherin Inhibits Dengue Virus Release from Human Hepatoma Cells
UNLABELLED Type I interferons (IFN) have been shown to play an important role for inhibiting Dengue virus (DENV) infection. Identifying IFN-induced cellular proteins are essential for understanding its mechanisms against DENV. Here we established stable Huh7-derived cell lines expressing the IFN-induced cell membrane protein BST2 (Huh7-BST2) or its variant bearing a V5 tag at the C-terminal (Hu...
متن کاملFoamy Virus Budding and Release
Like all other viruses, a successful egress of functional particles from infected cells is a prerequisite for foamy virus (FV) spread within the host. The budding process of FVs involves steps, which are shared by other retroviruses, such as interaction of the capsid protein with components of cellular vacuolar protein sorting (Vps) machinery via late domains identified in some FV capsid protei...
متن کاملTetherin Inhibits Cell-Free Virus Dissemination and Retards Murine Leukemia Virus Pathogenesis
The relative contributions of cell-free virion circulation and direct cell-to-cell transmission to retroviral dissemination and pathogenesis are unknown. Tetherin/Bst2 is an antiviral protein that blocks enveloped virion release into the extracellular milieu but may not inhibit cell-to-cell virus transmission. We developed live-cell imaging assays which show that tetherin does not affect Molone...
متن کاملNonintegrating foamy virus vectors.
Foamy viruses (FVs), or spumaviruses, are integrating retroviruses that have been developed as vectors. Here we generated nonintegrating foamy virus (NIFV) vectors by introducing point mutations into the highly conserved DD35E catalytic core motif of the foamy virus integrase sequence. NIFV vectors produced high-titer stocks, transduced dividing cells, and did not integrate. Cells infected with...
متن کاملThe glycoprotein of vesicular stomatitis virus promotes release of virus-like particles from tetherin-positive cells
Vesicular stomatitis virus (VSV) release from infected cells is inhibited by the interferon (IFN)-inducible antiviral host cell factor tetherin (BST-2, CD317). However, several viruses encode tetherin antagonists and it is at present unknown whether residual VSV spread in tetherin-positive cells is also promoted by a virus-encoded tetherin antagonist. Here, we show that the viral glycoprotein (...
