title: [Evidence for the production of a fusion factor during in vitro infection of sheep choroid plexus cells by visna virus].
abstract: One of the most important early events during the infection of sheep choroïd plexus cells in culture by Visna virus is the synthesis by these cells of a fusion factor distinct from the virus. The cell fusion activity of this factor does not seem transmissible. It promotes cell shape changes and a migration of the nucleus towards the cell wall.
