Abstract INTRODUCTION Human tau protein, composed of six brain‐specific isoforms, is a major driver of Alzheimer's disease (AD). The role of its isoforms however remains unclear and human AD models are scarce. METHODS We generated human MAPT– (tau–) knockout (KO) induced pluripotent stem cells (iPSC) using CRISPR/Cas9, differentiated these into ...

PDB_Amyloid: The Extended Live Amyloid Structure List from the PDB [PDF]
The Protein Data Bank (PDB) contains more than 135 000 entries today. From these, relatively few amyloid structures can be identified, since amyloids are insoluble in water. Therefore, mostly solid state NMR-recorded amyloid structures are deposited in the PDB.

A Physiological Role for Amyloid Beta Protein: Enhancement of Learning and Memory [PDF]
Amyloid beta protein (A[beta]) is well recognized as having a significant role in the pathogenesis of Alzheimer's disease (AD). The reason for the presence of A[beta] and its physiological role in non-disease states is not clear.

Dysregulation of Na+/K+ ATPase by amyloid in APP+PS1 transgenic mice [PDF]
BACKGROUND: The pathology of Alzheimer's disease (AD) is comprised of extracellular amyloid plaques, intracellular tau tangles, dystrophic neurites and neurodegeneration. The mechanisms by which these various pathological features arise are under intense

Premenopausal bilateral oophorectomy and Alzheimer's disease imaging biomarkers later in life
Abstract INTRODUCTION Premenopausal bilateral oophorectomy (PBO) before the age of 46 years is associated with an increased risk of dementia. We investigated the long‐term effects of PBO performed before age 50 years on amyloid beta (Aβ), tau, and neurodegeneration imaging biomarkers of Alzheimer's disease (AD).

Bimodality, prion aggregates infectivity and prediction of strain phenomenon [PDF]
We consider a model for the polymerization (fragmentation) process involved in infectious prion self-replication and study both its dynamics and non-zero steady state. We address several issues. Firstly, we give conditions leading to size repartitions of PrPsc aggregates that exhibit bimodal distributions, as indicated by recent experimental studies of

Astrocytic LRP1 mediates brain Aβ clearance and impacts amyloid deposition [PDF]
Accumulation and deposition of amyloid-β (Aβ) in the brain represent an early and perhaps necessary step in the pathogenesis of Alzheimer's disease (AD).

Microglial ApoD‐induced NLRC4 inflammasome activation promotes Alzheimer's disease progression
We found that NLRC4 inflammasome was activated in microglia releasing IL6 and TNF‐α to impair the hippocampal neural stem cells (NSCs) self‐proliferation. ApoD contributed to activating NLRC4 inflammasome in microglia. Targeting the ApoD provides beneficial effects on NSCs self‐proliferation and mature neurons survival.

Effect of Surfaces on Amyloid Fibril Formation [PDF]
Using atomic force microscopy (AFM) we investigated the interaction of amyloid beta (Ab) (1 42) peptide with chemically modified surfaces in order to better understand the mechanism of amyloid toxicity, which involves interaction of amyloid with cell membrane surfaces.
