HPV31型L2保守中和表位可诱发广谱中和抗体
Conservative epitope of human papillomavirus type 31 L2 can induce broad-spectrum neutralizing antibodies
摘要
Abstract
Objective To detect the immunogenicity of conservative neutralizing epitope from human papilloma-virus type 31 ( HPV31) minor capsid protein L2, and analyze the neutralizing antibody spectrum of its immune sera.Methods Synthesize HPV31 L2 aa.17-40 peptide and conjugate with KLH by EDC.Immunize New Zeal-and white rabbits with HPV31 L2-KLH and Freud's Adjuvant.Analyze the neutralizing antibody titers of immune sera against HPVs from α4,α7,α9,α10 and β1 species by pseudovirus neutralization assay.Results In rabbits, HPV31 L2-KLH induced broad-spectrum neutralizing antibodies against at least 17 types of HPV, among which the neutralizing antibody titers against HPV31 are the highest, followed by that of HPV5/45/57. Conclusions The broad-spectrum neutralizing activity of the immune sera of HPV31 L2 is stimulated by conser-vative neutralizing epitope.The results lay the foundation of the development of broad-spectrum HPV vaccines based on HPV31 L2 neutralizing epitope.关键词
