Abstract

VP7-specific neutralizing monoclonal antibodies (N-MAbs) to serotype 3 human rotavirus were produced to analyze serotype 3-specific and cross-reactive neutralization epitopes on VP7. On the basis of the reactivity patterns in neutralization tests with various human and animal strains, a total of 10 N-MAbs could be classified into four groups; five antibodies specific to serotype 3 were divided into two groups, and five antibodies consisted of two groups which are cross-reactive with strain 69 M (serotype 8) or strain WI61 (serotype 9). Seven N-MAbs showed the same reactivity patterns to the virus strains in both neutralization tests and enzyme-linked immunosorbent assay (ELISA), while three N-MAbs specific to serotype 3 in neutralization showed a cross-reactivity with the serotype 8 strain in ELISA. Neutralization-resistant mutants of serotype 3 strains P and YO were selected by the N-MAbs. Cross-neutralization tests between the mutants and the MAbs indicated the presence of two serotype-specific (S1 and S2) and three cross-reactive (C1, C2, and C3) epitope groups. S1, S2, and C3 epitope groups overlapped operationally each other, and the S1 epitope group had an overlapping with the C1 epitope group. However, C2 epitope group identified by the MAbs which neutralized serotypes 3 and 9, had no operational overlapping with any other epitope groups.
