The discovery and characterization of broadly neutralizing antibodies (bnAbs) against influenza viruses have raised hopes for the development of monoclonal antibody (mAb)-based immunotherapy and the design of universal influenza vaccines. Only one human bnAb (CR8020) specifically recognizing group 2 influenza A viruses has been previously characterized that binds to a highly conserved epitope at the base of the hemagglutinin (HA) stem and has neutralizing activity against H3, H7, and H10 viruses. Here, we report a second group 2 bnAb, CR8043, which was derived from a different germ-line gene encoding a highly divergent amino acid sequence. CR8043 has in vitro neutralizing activity against H3 and H10 viruses and protects mice against challenge with a lethal dose of H3N2 and H7N7 viruses. The crystal structure and EM reconstructions of the CR8043-H3 HA complex revealed that CR8043 binds to a site similar to the CR8020 epitope but uses an alternative angle of approach and a distinct set of interactions. The identification of another antibody against the group 2 stem epitope suggests that this conserved site of vulnerability has great potential for design of therapeutics and vaccines. 履歴 登録 2013年11月14日 登録サイト : RCSB / 処理サイト : RCSB改定 1.0 2013年12月25日 Provider : repository / タイプ : Initial release改定 1.1 2014年1月22日 Group : Database references改定 1.2 2017年6月21日 Group : Database references / Source and taxonomy / Structure summaryカテゴリ : entity_name_com / entity_src_gen ... entity_name_com / entity_src_gen / struct_ref / struct_ref_seq / struct_ref_seq_dif Item : _struct_ref.db_code / _struct_ref.db_name ... _struct_ref.db_code / _struct_ref.db_name / _struct_ref.entity_id / _struct_ref.pdbx_align_begin / _struct_ref.pdbx_db_accession / _struct_ref.pdbx_seq_one_letter_code / _struct_ref_seq.db_align_beg / _struct_ref_seq.db_align_end / _struct_ref_seq.pdbx_auth_seq_align_beg / _struct_ref_seq.pdbx_auth_seq_align_end / _struct_ref_seq.pdbx_db_accession / _struct_ref_seq.pdbx_strand_id / _struct_ref_seq.ref_id / _struct_ref_seq.seq_align_beg / _struct_ref_seq.seq_align_end 改定 1.3 2017年12月6日 Group : Database references / カテゴリ : pdbx_database_relatedItem : _pdbx_database_related.content_type / _pdbx_database_related.db_id改定 2.0 2020年7月29日 Group : Atomic model / Data collection ...
