引用 | ジャーナル: Nat Struct Mol Biol / 年: 2022 タイトル: Cryo-EM structure of disease-related prion fibrils provides insights into seeding barriers. 著者: Qiuye Li / Christopher P Jaroniec / Witold K Surewicz / 要旨: One of the least understood aspects of prion diseases is the structure of infectious prion protein aggregates. Here we report a high-resolution cryo-EM structure of amyloid fibrils formed by human ...One of the least understood aspects of prion diseases is the structure of infectious prion protein aggregates. Here we report a high-resolution cryo-EM structure of amyloid fibrils formed by human prion protein with the Y145Stop mutation that is associated with a familial prion disease. This structural insight allows us not only to explain previous biochemical findings, but also provides direct support for the conformational adaptability model of prion transmissibility barriers. | ||||||
