Monoclonal antibodies which block cellular receptors of poliovirus

Virus Res. 1984;1(3):203-12. doi: 10.1016/0168-1702(84)90039-x.

Abstract

The isolation and properties of monoclonal antibodies which specifically inhibit the binding of poliovirus types 1, 2 and 3 to cells are described. The antibodies were of the IgG class and blocked infection of cells by all strains of the three poliovirus serotypes, but by none of a wide range of other viruses examined, including nine human enteroviruses. The antibodies prevented poliovirus growth in all susceptible human and primate cells tested. We conclude that the antibodies are directed against the receptor site for poliovirus which is distinct from those required by other picornaviruses, and which seems to be antigenically well conserved between cells of human and primate origin.
