Do World Trade Center Responders Get Early Onset Plaques and Tangles?
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.

Human and Mouse Microglia React Differently to Amyloid
Single-nucleus transcriptomics of postmortem AD brain and mouse models of amyloidosis hammers home the species-specific responses of microglia to Aβ pathology.
Tau PET Scans Turn Positive When Amyloid Does; Symptoms Follow
Data from different next-generation tracers look similar. It shows spreading plaques kick off tangles by Braak region; memory starts slipping later.
2019—A Year of Hope for Alzheimer's Research
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.
Single-Cell Expression Atlas Charts Changes in Alzheimer’s Entorhinal Cortex
Specific patterns of expression defined distinct subtypes of neurons, astrocytes, oligodendrocytes, and microglia in this early affected brain region.
Exposure, Exposure, Exposure? At CTAD, Aducanumab Scientists Make a Case
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?
Cell-Specific Enhancer Atlas Centers AD Risk in Microglia. Again.
Cataloguing enhancer-promoter interactions in the four major cell types of the brain, researchers found that Alzheimer’s risk variants predominantly appeared in microglial enhancers.
Multimodal Imaging of Neurodegenerative Diseases Links Pathology and Cellular Dysfunction
Synapse loss and mitochondrial stress, as seen by separate PET tracers, go hand-in-hand in Alzheimer’s, Parkinson’s, and frontotemporal dementia.
Paper Alert: Phase 3 Trial Data Published on Sleep Aid Suvorexant
FDA approves adding safety and efficacy data from an Alzheimer’s trial to the drug’s label.
New Myelin Makes Memories, but Supply Wanes with Age
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.
Toxic α-Synuclein: Egged on by ApoE4, Thwarted by ApoE2?
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.
Topline Result for First DIAN-TU Clinical Trial: Negative on Primary
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.
A Central Role for Prion Protein in Neurodegeneration?
Researchers implicate PrP in the toxicity of Aβ, tau, and α-synuclein oligomers in several neurodegenerative diseases.
Retinal Gene Therapy Trial Posts Positive Result
Vision improved in some retinitis pigmentosa patients in a Phase 1 trial.
PET Tracer Detects Synapse Loss Across Alzheimer’s Brain
New research presented at the HAI conference also finds links between UCB-J uptake and plaques, tangles, and cognitive decline.
