Virus and host mechanics support membrane penetration and cell entry


Greber, Urs F (2016). Virus and host mechanics support membrane penetration and cell entry. Journal of Virology, 90(8):3802-3805.

Abstract

Viruses are quasi-inert macromolecular assemblies. Their meta-stable conformation changes during entry into cells, when chemical and mechanical host cues expose viral membrane-interacting proteins. This leads to membrane rupture or fusion, and genome uncoating. Importantly, virions tune their physical properties and enhance penetration and uncoating. For example, influenza virus softens at low pH to uncoat. Stiffness and pressure of adenovirus control uncoating and membrane penetration. Virus and host mechanics thus present new opportunities for anti-viral therapy.
