Antigenic Variation and Resistance to Neutralization in Poliovirus Type 1

Abstract: Mutations have been identified in variants of poliovirus, type 1 (Mahoney) on the basis of their resistance to neutralization by individual monoclonal antibodies. The phenotypes of these variants were defined in terms of antibody binding; the pattern of epitopes expressed or able to be exploited for neutralization were complex. Single amino acid changes can have distant (in terms of linear sequence) and generalized effects on the antigenic structure of poliovirus and similarly constituted virions.

“…The same is not true for the remaining three antibodies, and it is possible that each of the amino acid substitutions conferring resistance to AP7, API2 and LP2 occurs at some distance from the corresponding antibody binding site, but modifies the site by allosteric effects within the molecule. Mutations that confer antibody resistance by long-range effects have been observed in poliovirus (Diamond et al, 1985) and tobacco mosaic virus (A1 Moudallal et al, 1982), but in these instances protein-protein interactions play an important part in determining the secondary and tertiary structure of individual subunits. It seems unlikely that mutations could act at long range (i.e.…”

“…In contrast, frequencies of resistance to monoclonal antibody neutralization for poliovirus are in the range 10-3 to 10-5 base substitutions per site (29,30). In vitro measurements of poliovirus polymerase error frequencies (31) and the mutation frequency of poliovirus type 1 to a high degree of resistance to guanidine indicated specific single-site mutation frequencies for poliovirus of the order of 10-3 to 10-4 (32,33).…”

“…However the results reported here imply that antibodies may appear to react with peptide sequences which are not recognized in the native antigen and that little of the peptide may be in the appropriate conformation to induce cross-reactive antibodies. Emini et al (1983) used the reactions of monoclonal antibodies with synthetic peptides to identify antigenic sites on type 1 poliovirus and these studies led to the conclusion that mutations were frequently located outside the antibody-binding site (Diamond et al, 1985;Blondel et al, 1986). However this conclusion is difficult to reconcile with the three-dimensional structure of type 1 poliovirus (Hogle et al, 1985).…”
