Abstract:
:The entry of animal viruses into cells is associated with permeabilization of the infected cells to protein toxins such as alpha-sarcin (C. Fernández-Puentes and L. Carrasco, Cell 20:769-775, 1980). This phenomenon has been referred to as "the early permeabilization by animal viruses" (L. Carrasco, Virology 113:623-629, 1981). A number of inhibitors of poliovirus growth such as WIN 51711 6-(3,4-dichlorophenoxy)-3-(ethylthio)-2-pyridincarbonitrile (DEPC) and Ro 09-0410 specifically block the uncoating step of poliovirus but have no effect on attachment or entry of poliovirus particles into cells. These agents are potent inhibitors of the early permeabilization induced by poliovirus to the toxin alpha-sarcin. Thus, the uncoating of poliovirus is required for the permeabilization of cell membranes to proteins. The increased entry of labeled heparin promoted by virus entry is not blocked by these agents, indicating that poliovirus binds to its receptor and is internalized along with heparin in endosomes in the presence of WIN 51711, DEPC, or Ro 09-0410. We conclude that the delivery to the cytoplasm of some molecules that coenter with virion particles does not take place if the uncoating process is hindered.
