Induced neurons lacking the Alzheimer’s risk gene can’t properly recycle APP.
Using a form of confocal microscopy and automated software, the method allows researchers to rapidly identify functional synapses within brain structures.
The modeling approach reinforces the idea that tau pathology propagates through the brain’s physical architecture, including neuronal networks.
Built to cross the blood-brain barrier, the vehicle delivers therapeutic antibodies, enzymes, and potentially small molecules such as oligonucleotides.
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.
The plasma biomarker neurofilament light was able to distinguish individual mutation carriers from noncarriers three years prior to onset.
Separately, cerebrovascular disease drove an uptick in neurofilament light in the brain, indicating neurodegeneration.
Chemicals and particulates may slip across the blood-brain barrier or travel up olfactory nerves to directly affect brain cells. What are the consequences for cognition?
Growing evidence suggests exposure to air pollution increases risk of brain damage and dementia. More definitive research is needed.
According to a structural analysis, fluorescently tagged tau fragments cannot form paired helical filaments. This suggests the assay does not measure prion-like propagation.
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?
A large, cross-sectional study finds that RO-948 PET discriminates AD dementia from other disorders more accurately than do CSF biomarkers or MRI.
This update of the Allen Brain Institute atlas reveals detailed anatomical structures and provides a common framework for comparing brain datasets.
Hippocampal imaging and fluid markers of BBB damage found in ApoE4 carriers.
