However, the interplay between hereditary ... Heterozygous point mutations of α-synuclein (α-syn) have been linked to the early onset and rapid progression of familial Parkinson's diseases (fPD). However, the interplay between hereditary mutant and wild-type (WT) α-syn and its role in the exacerbated pathology of α-syn in fPD progression are poorly understood. Here, we find that WT mice inoculated with the human E46K mutant α-syn fibril (hE46K) strain develop early-onset motor deficit and morphologically different α-syn aggregation compared with those inoculated with the human WT fibril (hWT) strain. By using cryo-electron microscopy, we reveal at the near-atomic level that the hE46K strain induces both human and mouse WT α-syn monomers to form the fibril structure of the hE46K strain. Moreover, the induced hWT strain inherits most of the pathological traits of the hE46K strain as well. Our work suggests that the structural and pathological features of mutant strains could be propagated by the WT α-syn in such a way that the mutant pathology would be amplified in fPD. 履歴 登録 2020年5月3日 登録サイト : PDBJ / 処理サイト : PDBJ改定 1.0 2021年5月5日 Provider : repository / タイプ : Initial release改定 1.1 2022年5月18日 Group : Database references / カテゴリ : citation / citation_author / database_2Item : _citation.country / _citation.journal_abbrev ... _citation.country / _citation.journal_abbrev / _citation.journal_id_ASTM / _citation.journal_id_CSD / _citation.journal_id_ISSN / _citation.journal_volume / _citation.pdbx_database_id_DOI / _citation.pdbx_database_id_PubMed / _citation.title / _citation.year / _database_2.pdbx_DOI / _database_2.pdbx_database_accession 改定 1.2 2024年5月29日 Group : Data collection / カテゴリ : chem_comp_atom / chem_comp_bond
