Middle-aged WTC responders have cognitive problems, which correlate not only with their PTSD symptoms and exposure to toxic dust, but also with biomarkers of amyloid and tau.
Functional connections between two brain regions are the strongest indicator that pathologic, accumulated tau will spread from one to another.
When observed over an eight-year period, people with the highest plasma concentrations were more likely to die than people with lower levels.
New study finds no uptick in herpes viruses in AD. If herpes plays a role, it says, then probably it acts as an early trigger of pathology.
Aβ oligomers latch onto adrenergic receptors, mobilizing a kinase that phosphorylates tau. Blocking adrenergic signaling wards off memory problems in amyloidosis mice.
These oily microglia resemble the foamy macrophages seen in atherosclerotic plaques. They correlate with aging, inflammation, and neurodegenerative disease.
Single-nucleus transcriptomics of postmortem AD brain and mouse models of amyloidosis hammers home the species-specific responses of microglia to Aβ pathology.
Three studies found no link between vascular disease and cerebral amyloidosis.
Positive allosteric modulators improve learning and memory in mouse models of AD and epilepsy.
In Alzheimer’s brain, granulovacuolar bodies in neurons harbor activated necrosomes. They correlate with tau pathology and neuron loss, raising new questions about how neurons die in this disease.
The cells are primed to attack. Their targets include Epstein-Barr virus peptides.
In early Alzheimer’s disease, the pattern of tau deposition also strongly predicts areas destined for subsequent degeneration.
Besides further broadening the Alzheimer’s therapeutic pipeline, researchers urge a return to Phase 2, using artificial intelligence tools to streamline aspects of trials.
Data from different next-generation tracers look similar. It shows spreading plaques kick off tangles by Braak region; memory starts slipping later.
