The Microbiome and Disease—What Does Poop Have to Do With It?
Simple lifestyle factors such as alcohol consumption and stool quality alter gut flora. Research on the microbiome and disease should account for those factors, a study reports.
FDA Advisory Committee Throws Cold Water on Aducanumab Filing
The panel considered the evidence for efficacy to be weak, and was troubled by too-close collaboration between the sponsor and the FDA.
BAN2401 Forges AHEAD into Phase 3, Preclinical AD
The anti-Aβ biologic will be put to the test in two stages of preclinical Alzheimer’s, designated by amyloid load. The long-dormant “est” PET tracer, NAV4694, is on board to make sensitive measurements.
BANish Aβ? BAN2401 Antibody Makes Its Move in Phase 3 Program
At CTAD, a Phase 2 open-label extension of this anti- Aβ protofibril antibody posted data as expected, and new Phase 3 trials for people with early and preclinical Alzheimer’s were described.
TRC-PAD Funnel Finally Touches Down
After years of building an online registry, designing selection algorithms, and getting sites up and running, COVID-19 nearly derailed this trial-ready cohort once again. Now, the first participants have reached the final queue.
Does Astrocyte Tau Cause Dementia?
In mice, accumulation of tau in hilar astrocytes of the dentate gyrus spells trouble for the hippocampus and for spatial memory.
Learning Troubles Spied by Smartphone Track with Biomarkers
Remote assessments on a smartphone closely matched tests taken in the clinic. They also may detect slip-ups in learning—an earlier cognitive deficit that arises in preclinical AD.
In Phase 2 Trial, Neflamapimod Aids Cognition in Lewy Body Dementia
After missing primary endpoints in Alzheimer’s trials, this p38 MAPKa inhibitor gained some traction in a test in people with DLB.
Plasma Aβ Test Wins Approval—Are p-Tau Tests Far Behind?
Regulators in the U.S. and Europe have certified a mass-spectrometry-based blood test for amyloid-β. Plasma phospho-tau markers are poised to come next.
Do Endothelial Cells Spur Capillaries to Grow in Alzheimer’s Brain?
A new single-nucleus RNA-Seq study of 3,900 endothelial cells finds a boost in angiogenesis and antigen presentation genes, drawing attention to the vascular component of AD.
Individualized Tau PET Model Outperforms Predictive Power of Braak Staging
By pinpointing where tau pathology starts in a person’s brain, researchers better predicted future spread and determined small changes in tangle load.
Protective AD Variant Pinpoints Sweet Spot for Microglial Activation
Phospholipase C-γ2 acts downstream of TREM2 to rev up beneficial inflammation, phagocytosis, and cell survival.
Paper Alert: Trafficking Variants Cause BACE Buildup in Axons
In mice lacking the recycling protein GGA3, BACE1 trafficking stalls, local Aβ production increases, and axons swell. Does this explain the neuritic dystrophies seen in early AD?
Aducanumab Still Needs to Prove Itself, Researchers Say
While the FDA weighs aducanumab’s marketing license application, Alzheimer’s researchers agree that the agency’s own statistician correctly assessed the data as weak. Most prefer that one more trial be done.
