BST2

Immune System · Interferon Cascades & Antiviral Defense

How can BST2 help keep a virus from spreading between cells?

BST2 makes tetherin, a cell-surface protein that can restrict the release of certain enveloped viruses. This antiviral mechanism is one part of innate defense and does not predict a person's protection from a particular infection.
