[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.
