  引用ジャーナル : Cell  /  年 : 2020タイトル : Cryo-EM Reveals Integrin-Mediated TGF-β Activation without Release from Latent TGF-β.著者 : Melody G Campbell  /  Anthony Cormier  /  Saburo Ito  /  Robert I Seed  /  Andrew J Bondesson  /  Jianlong Lou  /  James D Marks  /  Jody L Baron  /  Yifan Cheng  /  Stephen L Nishimura  /  要旨 : Integrin αvβ8 binds with exquisite specificity to latent transforming growth factor-β (L-TGF-β). This binding is essential for activating L-TGF-β presented by a variety of cell types.  ... Integrin αvβ8 binds with exquisite specificity to latent transforming growth factor-β (L-TGF-β). This binding is essential for activating L-TGF-β presented by a variety of cell types. Inhibiting αvβ8-mediated TGF-β activation blocks immunosuppressive regulatory T cell differentiation, which is a potential therapeutic strategy in cancer. Using cryo-electron microscopy, structure-guided mutagenesis, and cell-based assays, we reveal the binding interactions between the entire αvβ8 ectodomain and its intact natural ligand, L-TGF-β, as well as two different inhibitory antibody fragments to understand the structural underpinnings of αvβ8 binding specificity and TGF-β activation. Our studies reveal a mechanism of TGF-β activation where mature TGF-β signals within the confines of L-TGF-β and the release and diffusion of TGF-β are not required. The structural details of this mechanism provide a rational basis for therapeutic strategies to inhibit αvβ8-mediated L-TGF-β activation. 履歴 登録 2019年10月2日 登録サイト  : RCSB /  処理サイト  : RCSB改定 1.0 2020年2月5日 Provider  : repository /  タイプ  : Initial release改定 1.1 2020年2月19日 Group  : Database references /  カテゴリ  : citation /  Item  : _citation.journal_volume /  _citation.page_first改定 2.0 2020年7月29日 Group  : Atomic model /  Data collection ...
