要旨: Persistent, high-risk human papillomavirus (HPV) infection is the primary cause of cervical cancer. Neutralizing antibodies elicited by L1-only virus-like particles (VLPs) can block HPV infection; ...Persistent, high-risk human papillomavirus (HPV) infection is the primary cause of cervical cancer. Neutralizing antibodies elicited by L1-only virus-like particles (VLPs) can block HPV infection; however, the lack of high-resolution structures has limited our understanding of the mode of virus infection and the requirement for type specificity at the molecular level. Here, we describe two antibodies, A12A3 and 28F10, that specifically bind to and neutralize HPV58 and HPV59, respectively, through two distinct binding stoichiometries. We show that the epitopes of A12A3 are clustered in the DE loops of two adjacent HPV58 L1 monomers, whereas 28F10 recognizes the HPV59 FG loop of a single monomer. Via structure-based mutagenesis and analysis of antibody binding, we further identified the residues HPV58 D154, S168, and N170 and HPV59 M267, Q270, E273, Y276, K278, and R283, which play critical roles in virus infection. By substituting these strategic epitope residues into other HPV genotypes, we could then redirect the type-specific binding of the antibodies to these genotypes, thus highlighting the importance of these specific residues, HPV58 R161, S168, and N308 and HPV59 Q270, E273, and D281. Overall, our findings provide molecular insights into potential structural determinants of HPV required for infectivity and type specificity. High-risk human papillomaviruses (HPVs) are considered the major causative pathogens of cancers that affect epithelial mucosa, such as cervical cancer. However, because of the lack of high-resolution structural information on the sites of neutralization, we have yet to determine the precise mode of HPV infection and how different types of HPV cause infection. Our crystal structures in this study have uncovered discrete binding stoichiometries for two different antibodies. We show that one A12A3 Fab binds to the center of one HPV58 pentamer, whereas five 28F10 Fabs bind along the top fringe of one HPV59 pentamer. Furthermore, through targeted epitope analysis, we show that 6 to 7 discontinuous residues of the L1 major capsid protein of HPV are determinants, at least in part, for virus infection and type specificity. This knowledge will help us to unravel the process of HPV infection and can potentially be used to drive the development of therapeutics that target neutralization-sensitive sites.

2019年1月31日: EMDBのIDの桁数の変更

EMDBのIDの桁数の変更

  • EMDBエントリに付与されているアクセスコード(EMDB-ID)は4桁の数字(例、EMD-1234)でしたが、間もなく枯渇します。これまでの4桁のID番号は4桁のまま変更されませんが、4桁の数字を使い切った後に発行されるIDは5桁以上の数字(例、EMD-12345)になります。5桁のIDは2019年の春頃から発行される見通しです。
  • EM Navigator/万見では、接頭語「EMD-」は省略されています。

2017年7月12日: PDB大規模アップデート

PDB大規模アップデート

  • 新バージョンのPDBx/mmCIF辞書形式に基づくデータがリリースされました。
  • 今回の更新はバージョン番号が4から5になる大規模なもので、全エントリデータの書き換えが行われる「Remediation」というアップデートに該当します。
  • このバージョンアップで、電子顕微鏡の実験手法に関する多くの項目の書式が改定されました(例:em_softwareなど)。
  • EM NavigatorとYorodumiでも、この改定に基づいた表示内容になります。

外部リンク:wwPDB Remediation / OneDepデータ基準に準拠した、より強化された内容のモデル構造ファイルが、PDBアーカイブで公開されました。
