The antiviral protein enhances γ-secretase processing of APP. More of it is present in Alzheimer’s disease.
Learning tests may prove more informative in clinical trials of early AD. A new one claims it can spot a difference in six days.
By analyzing a single MRI scan, researchers pinpointed the origin of frontotemporal dementia pathology and predicted its future progression.
DAPPD suppressed neuroinflammation and preserved cognition in mouse models of amyloidosis, suggesting potential for treating Alzheimer’s disease.
In a mouse tauopathy model, knocking out the NLRP3 inflammasome prevented toxic tau from forming.
Single-nucleus transcriptomics of postmortem AD brain and mouse models of amyloidosis hammers home the species-specific responses of microglia to Aβ pathology.
Biogen researchers claim the antibody worked in people who got enough of it. To other researchers, the signal validates the amyloid hypothesis and injects fresh energy into the field. But is this interrupted dataset enough to approve?
Hippocampal imaging and fluid markers of BBB damage found in ApoE4 carriers.
With experiments and careers on hold, scientists working from home are turning to virtual lab meetings and journal clubs to keep up morale.
When these tiny mural cells carried APOE4, they secreted more ApoE, causing Aβ to deposit in capillary walls. Blocking ApoE production prevented angiopathy.
Live imaging of mouse brain reveals that microglia quickly engulf cell bodies while astrocytes dispose of the neuron’s more distal reaches. The cleanup crew tires with age.
According to a structural analysis, fluorescently tagged tau fragments cannot form paired helical filaments. This suggests the assay does not measure prion-like propagation.
In mice with defective PS1 phosphorylation, microglial autophagy falters, exacerbating Aβ burden.
The first high-resolution look at LRRK2 implies that pathogenic mutations increase binding to microtubules by biasing the kinase domain toward a closed, active conformation.
A C9ORF72 polydipeptide repeat induces aggregation by direct interaction with TDP-43, while progranulin mutations that trigger microglial toxicity cause TDP-43 to accumulate via complement.
