PS1 P264L

RESEARCH MODELS Summary The PS1 P264L knock-in mouse line was derived using a two-step mutagenesis strategy similar to that used to generate the TgAPPSwe-KI line (Reaume et al., 1996). An advantage to this model is the mutant PSEN1 is expressed at normal levels and under

TgAPPSwe-KI

RESEARCH MODELS Summary This model was generated using a gene-targeting strategy designed to enhance the production of human Aβ in the mouse brain without changing APP synthesis. Site-specific mutations were introduced into exon 16 of the mouse APP gene to humanize the A

hBACE54

RESEARCH MODELS Summary These mice were generated to determine how BACE overexpression affects the processing of APP in vivo. Two transgenic lines were reported (BACE54/4 and BACE54/11) both expressing human BACE at high levels in the brain. Human BACE mRNA was approxima

Tau V337M

RESEARCH MODELS Modification Details Human 4-repeat tau driven by the PDGF-β promoter. Tagged with myc and Flag on the N- and C-terminals respectively. Neuropathology SDS-insoluble tau aggregates in hippocampus. Degenerating neurons in the hippocampus containing phosphor

Tau R406W transgenic

RESEARCH MODELS Modification Details Transgene containing human 4-repeat tau cDNA with the R406W mutation containing myc and FLAG tags at N-and C-terminal ends, respectively, and driven by the CaMK-II promoter. Neuropathology Argyrophilic and congophilic tau inclusions i

hBACE

RESEARCH MODELS Summary Three lines of transgenic mice expressing different levels of human BACE were generated. Line 30 (BACE-L) expressed the lowest amount of BACE, followed by line 34 (BACE-M), and line 8 (BACE-H). These lines expressed human BACE at levels approximat

Turning to the Internet for Alzheimer’s Trial Volunteers

CONFERENCE COVERAGE 2013-11-27 Conference Coverage Slow enrollment often hobbles Alzheimer’s clinical trials. At a November 1–2 meeting at the Cleveland Clinic Lou Ruvo Center for Brain Health in Las Vegas, stakeholders brainstormed ways to reach new participants and keep them engaged.

Do Tau Tracers Track Cognitive Decline in Disease?

CONFERENCE COVERAGE 2013-11-27 Conference Coverage Pathology studies show that tau tangles, unlike amyloid, track closely with the cognitive decline of Alzheimer’s disease. This has raised hope that the tau PET tracers being developed will allow researchers to stage disease, and early
