Unlike AD, FTD begins with behavioral changes before the development of cognitive impairment. Dominantly inherited mutations in MAPT, the microtubule-associated protein tau gene, give rise to cases of FTD and parkinsonism linked to chromosome 17. These individuals develop abundant filamentous tau inclusions in brain cells in the absence of β-amyloid deposits. Here, we used cryo-electron microscopy to determine the structures of tau filaments from the brains of human MAPT mutants V337M and R406W. Both amino acid substitutions gave rise to tau filaments with the Alzheimer fold, which consisted of paired helical filaments in all V337M and R406W cases and of straight filaments in two V337M cases. We also identified another assembly of the Alzheimer fold into triple tau filaments in a V337M case. Filaments assembled from recombinant tau (297-391) with substitution V337M had the Alzheimer fold and showed an increased rate of assembly. #1: ジャーナル: bioRxiv / 年: 2024 タイトル: Tau filaments with the Alzheimer fold in cases with mutations V337M and R406W. 著者: Chao Qi / Sofia Lövestam / Alexey G Murzin / Sew Peak-Chew / Catarina Franco / Marika Bogdani / Caitlin Latimer / Jill R Murrell / Patrick W Cullinane / Zane Jaunmuktane / Thomas D Bird / ...著者: Chao Qi / Sofia Lövestam / Alexey G Murzin / Sew Peak-Chew / Catarina Franco / Marika Bogdani / Caitlin Latimer / Jill R Murrell / Patrick W Cullinane / Zane Jaunmuktane / Thomas D Bird / Bernardino Ghetti / Sjors H W Scheres / Michel Goedert / ![]() 要旨: Frontotemporal dementia (FTD) and Alzheimer's disease are the most common forms of early-onset dementia.

Dominantly inherited mutations in , the microtubule-associated protein tau gene, cause FTD and parkinsonism linked to chromosome 17 (FTDP-17).
