In a Phase 2 trial, the vaccine reportedly normalized the rise in plasma NfL, and appeared to lower CSF tau and retard brain atrophy.
At Tau2020 conference, scientists implicate LDL receptor-related protein 1 in cell-to-cell transmission.
In a mouse model of amyloidosis, human wild-type TREM2 kept Aβ deposition at bay early on, but this defense became overwhelmed as plaques grew. The R47H AD risk variant never offered protection early on, and made things worse later.
The first topline Phase 2 results from an antibody targeting Parkinson’s pathology, Roche’s prasinezumab, were a mixed bag. Next steps are unclear.
New Assay, New Cohorts—Plasma p-Tau181 Looks Even Better 217—The Best Phospho-Tau Marker for Alzheimer’s? In DIAN-TU, Gantenerumab Brings Down Tau. By a Lot. Open Extension Planned Confused About the DIAN-TU Trial Data? Experts Discuss Active Tau Vaccine: ...
Researchers at the online AAT-AD/PD meeting touted therapies that target neuroinflammation, synapses, epigenetic regulation, or the cortisol stress response.
For several neurodegenerative diseases, scientists identified which cell types exert a person’s inherited risk. In Alzheimer’s, it’s microglia; in Parkinson’s, it’s dopaminergic and enteric neurons—and oligodendrocytes.
Trialists are shooting new arrows at the disease, including compounds that tweak autophagy, neuroinflammation, and glycolipid recycling.
Chemicals and particulates may slip across the blood-brain barrier or travel up olfactory nerves to directly affect brain cells. What are the consequences for cognition?
Growing evidence suggests exposure to air pollution increases risk of brain damage and dementia. More definitive research is needed.
Using a form of confocal microscopy and automated software, the method allows researchers to rapidly identify functional synapses within brain structures.
People who lived in impoverished neighborhoods in their last year of life had greater odds of having died with AD neuropathology.
Islet amyloid protein and Aβ fibrils share similar folds.
Researchers used PET scans from 4,000 people to link RBFOX1 risk variants to amyloidosis. People with lower RBFOX1 expression in their brains had more amyloid and worse cognition.
Autopsy data confirm that current tau PET tracers are unsuitable for some primary tauopathies. CryoEM structures help researchers find new ligands for tau and α-synuclein.
