Tetherin
Tetherin is a membrane-associated protein that may prevent the release of enveloped viruses from their host cellsTetherin is a membrane-associated protein that may prevent the release of enveloped viruses from their host cells
Tetherin has been shown to prevent the release of HIV-1 virions and may be an effective inhibitor of other enveloped viruses as well such as Lassa and Marburg viruses. Tetherin inhibits the release of virions by binding to viral particles budding from the cell membrane, preventing the release of these infectious particles. The tetherin protein is always found on the surface of B lymphocytes, dendritic cells, and activated T lymphocytes. In brain, kidney, liver, skeletal muscle, pancreas and heart cells, the tetherin gene can be stimulated to be expressed by the production of alpha Interferon, a cytokine.
