Single-nucleus transcriptomics of postmortem AD brain and mouse models of amyloidosis hammers home the species-specific responses of microglia to Aβ pathology.
Data from different next-generation tracers look similar. It shows spreading plaques kick off tangles by Braak region; memory starts slipping later.
Happy New Year, readers! Yes, 2019 has passed, but so much happened last year that capturing the essence took longer than usual. Our mega year-end story is now posted for your reading pleasure.
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?
Synapse loss and mitochondrial stress, as seen by separate PET tracers, go hand-in-hand in Alzheimer’s, Parkinson’s, and frontotemporal dementia.
FDA approves adding safety and efficacy data from an Alzheimer’s trial to the drug’s label.
The creation of long-term memories requires a continual supply of myelin provided by newly formed oligodendrocytes. Alas, the generation of fresh oligodendrocytes diminishes with age, along with memory.
Quite independently of what it does to Aβ or tau, ApoE4 stokes α-synuclein pathology in mouse models. People with Lewy body dementia who carry ApoE4 had more phosphorylated synuclein in their brains, and their cognition declined faster.
DIAN, Roche, Lilly disclose that neither gantenerumab nor solanezumab slowed cognitive decline in the first-pass comparison of drug and placebo groups. Analyses are ongoing; dose may have been too low.
Researchers implicate PrP in the toxicity of Aβ, tau, and α-synuclein oligomers in several neurodegenerative diseases.
Vision improved in some retinitis pigmentosa patients in a Phase 1 trial.
New research presented at the HAI conference also finds links between UCB-J uptake and plaques, tangles, and cognitive decline.
Amyloid and tau PET are helping scientists pinpoint the underlying cause of specific AD symptoms. Perhaps imaging of certain brain regions will help predict an individual’s progression.
At HAI 2020, scientists more precisely quantified the relationship between plaques, tangles, and cognitive decline.
When observed over an eight-year period, people with the highest plasma concentrations were more likely to die than people with lower levels.
