Abstract

- Prophylactic vaccines against human papillomavirus (HPV) based on virus-like particles (VLP) induce type-specific neutralizing antibodies against a small number of hypervariable residues positioned in surface-exposed loops of the major capsid protein L1. To investigate the importance of these residues for neutralization, cross-neutralization, L2 incorporation and genome encapsidation, ten surface-exposed amino acid residues in four hypervariable loops of L1 were mutated. VLPs containing mutated or WT L1, with or without WT L2, were produced in 293TT cells using pseudovirion expression vectors. The mutations reduced the ability to induce neutralizing antibodies and to incorporate the L2 protein in the capsid. Ability to induce cross-neutralizing antibodies and to encapsidate pseudogenomes were completely abrogated. In summary, the surface-exposed L1 loops are important for the function of the HPV particle.
