Hippocampal imaging and fluid markers of BBB damage found in ApoE4 carriers.
According to a structural analysis, fluorescently tagged tau fragments cannot form paired helical filaments. This suggests the assay does not measure prion-like propagation.
Loss-of-function variants in the demethylase TET2 raise a person’s risk for early and late-onset Alzheimer’s, as well as FTD and ALS, suggesting a common mechanism.
A large, cross-sectional study finds that RO-948 PET discriminates AD dementia from other disorders more accurately than do CSF biomarkers or MRI.
Harvard or MIT? The microbiomes of mice raised in different facilities dictated their response to C9 deficiency, including whether they died young. Do gut microbes influence ALS?
Built to cross the blood-brain barrier, the vehicle delivers therapeutic antibodies, enzymes, and potentially small molecules such as oligonucleotides.
Grown on doughnut-shaped supports, the cultures survive for years. They offer a versatile system for studying Alzheimer’s disease, the authors claim.
This update of the Allen Brain Institute atlas reveals detailed anatomical structures and provides a common framework for comparing brain datasets.
Separately, cerebrovascular disease drove an uptick in neurofilament light in the brain, indicating neurodegeneration.
The plasma biomarker neurofilament light was able to distinguish individual mutation carriers from noncarriers three years prior to onset.
The modeling approach reinforces the idea that tau pathology propagates through the brain’s physical architecture, including neuronal networks.
Avid’s postmortem validation data indicate Alzheimer’s can be diagnosed by visual examination of flortaucipir PET scans.
Award recognizes discoveries of genetic variants that perturb liquid-liquid phase separation and increase risk for ALS-FTD and other neurodegenerative diseases.
Umbilical cord stem cells from presenilin 1 E280A carriers, once differentiated into cholinergic-like neurons, pumped out Aβ42 and accumulated phosphorylated tau and apoptotic markers.
In stark contrast to Aβ and tau fibrils, α-synuclein fibrils are asymmetric, comprising two different protofibrils.
