Journal ArticleDOI

Manuela Neumann,Deepak M. Sampathu,Linda K. Kwong,Adam C. Truax,Matthew Micsenyi,Thomas T. Chou,Jennifer Bruce,Theresa Schuck,Murray Grossman,Christopher M. Clark,Leo McCluskey,Bruce L. Miller,Eliezer Masliah,Ian R. A. Mackenzie,Howard Feldman,Wolfgang Feiden,Hans A. Kretzschmar,John Q. Trojanowski,Virginia M.-Y. Lee +18 more
TL;DR: It is shown that TDP-43 is the major disease protein in both frontotemporal lobar degeneration with ubiquitin-positive inclusions and amyotrophic lateral sclerosis.

Wenk,Tony Wyss-Coray +36 more
TL;DR: By better understanding AD inflammatory and immunoregulatory processes, it should be possible to develop anti-inflammatory approaches that may not cure AD but will likely help slow the progression or delay the onset of this devastating disorder.
Journal ArticleDOI
Expanded GGGGCC hexanucleotide repeat in noncoding region of C9ORF72 causes chromosome 9p-linked FTD and ALS
Mariely DeJesus-Hernandez,Ian R. A. Mackenzie,Bradley F. Boeve,Adam L. Boxer,Matt Baker,Nicola J. Rutherford,Alexandra M. Nicholson,Ni Cole A. Finch,Heather C. Flynn,Jennifer Adamson,Naomi Kouri,Aleksandra Wojtas,Pheth Sengdy,Ging-Yuek Robin Hsiung,Anna Karydas,William W. Seeley,Keith A. Josephs,Giovanni Coppola,Daniel H. Geschwind,Zbigniew K. Wszolek,Howard Feldman,Howard Feldman,David S. Knopman,Ronald C. Petersen,Bruce L. Miller,Dennis W. Dickson,Kevin B. Boylan,Neill R. Graff-Radford,Rosa Rademakers +28 more
TL;DR: It is found that repeat expansion in C9ORF72 is a major cause of both FTD and ALS, suggesting multiple disease mechanisms.
Journal ArticleDOI
Mutations in progranulin cause tau-negative frontotemporal dementia linked to chromosome 17
Matt Baker,Ian R. A. Mackenzie,Stuart Pickering-Brown,Jennifer Gass,Rosa Rademakers,Caroline Lindholm,Julie S. Snowden,Jennifer Adamson,A. Dessa Sadovnick,Sara Rollinson,Ashley Cannon,Emily Dwosh,David Neary,Stacey Melquist,Anna Richardson,Dennis W. Dickson,Zdenek Berger,Jason L. Eriksen,Todd Robinson,Cynthia Zehr,Chad A. Dickey,Richard Crook,Eileen McGowan,David M. A. Mann,Bradley F. Boeve,Howard Feldman,Mike Hutton +26 more
TL;DR: It is demonstrated that in multiple FTD families with significant evidence for linkage to the same region on chromosome 17q21, FTD is caused by mutations in progranulin (PGRN) that are likely to create null alleles and identified mutations in PGRN as a cause of neurodegenerative disease.
Journal ArticleDOI

TL;DR: Evidence from many independent research centers strongly supports the existence of a specific disease, as defined by the presence of A&bgr; plaques and neurofibrillary tangles.
