Definition of viropexis in English:



  • [mass noun] The process by which a virus particle becomes attached to a cell wall and incorporated into the cell by phagocytosis.

    • ‘Virosomes were taken up by Vero cells by viropexis with no evidence of fusion.’
    • ‘This process is known as viropexis where the virus membrane does not become part of the vesicle membrane.’
    • ‘With nonenveloped viruses, both viropexis and fusion mechanisms of entry have been reported but more emphasis has been given to changes in virion structure as a result of attachment than to the details by which the virus gains access to particular intracellular sites.’
    • ‘The penetration of the virions is by pinocytosis (viropexis); fusion with the cellular membrane has not been observed.’


1940s: from virus + Greek pēxis fixing.
