Characterization of a major neutralizing epitope on human papillomavirus type 16 L1.

ABSTRACT: Persistent infection with human papillomavirus type 16 (HPV-16) is strongly associated with the development of cervical cancer. Neutralizing epitopes present on the major coat protein, L1, have not been well characterized, although three neutralizing monoclonal antibodies (MAbs) had been identified by using HPV-16 pseudovirions (R. B. Roden et al., J. Virol. 71:6247-6252, 1997). Here, two of these MAbs (H16.V5 and H16.E70) were demonstrated to neutralize authentic HPV-16 in vitro, while the third (H16.U4) did not. Binding studies were conducted with the three MAbs and virus-like particles (VLPs) composed of the reference L1 sequence (114K) and three variant L1 sequences: Rochester-1k (derived from viral stock DNA), GU-1 (derived from cervical biopsy DNA), and GU-2 (derived from biopsy DNA,
