Virus-cell membrane interface

The virus–cell membrane interface refers to the dynamic contact zone where a virus interacts with a host cell's plasma membrane, enabling key life cycle stages such as viral attachment, membrane fusion (in enveloped viruses), and entry into the host cytosol[1][3]. This process involves viral proteins (such as fusion glycoproteins) associating with host cell receptors or attachment factors, membrane lipid rearrangement, and the eventual transfer of viral genetic material into the cell. The properties and mechanisms of the interface can vary widely by virus and cell type. Although critical for viral infection and a focus of antiviral drug development, the interface itself is not a discrete molecular entity or canonical target for therapeutics but a functional process involving numerous molecular actors[1][2][3].
