Abstract

There has been much incongruence in reports addressing the rate at which papillomaviruses enter cultured cells. We used a recently developed QRT-PCR assay (J. Virol. Methods 111 (2003) 135) to analyze the expression, adsorption, and entry kinetics of human papillomavirus type 11 (HPV-11) in multiple cell lines. Parallel experiments with HPV-40 and cottontail rabbit papillomavirus (CRPV) were also performed with biologically relevant lines. Infection was determined by the expression of early transcripts containing the E1∧E4 splice junction. Results support previous observations that papillomaviruses may enter cultured cells much more slowly than rates reported for similarly structured viruses (Virology 207 (1995) 136; Virology 307 (2003) 1; J. Virol. 75 (2001) 1565). Additionally, our data suggest that, following adsorption to the cell surface, capsomeric structure remains largely unchanged for many hours as HPV-11 virions remain equally susceptible to neutralization by a nonspecific microbicide and by L1-specific monoclonal antibodies (MAb) targeting both linear and conformationally sensitive epitopes.
