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.
At Quebec conference, researchers considered multiple aspects of herpesvirus biology that may come in to play in AD.
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.
In patient-derived neurons, tau mutations scupper lysosomes and SORLA shunts APP through different types of endosomes.
Using a form of confocal microscopy and automated software, the method allows researchers to rapidly identify functional synapses within brain structures.
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.
At the HAI 2020 conference, the tracers PI-2620 and APN-1607 appeared to bind frontotemporal dementia tau. MK-6240 looked highly sensitive. And JNJ-067 and SNFT-1 are two new kids in town.
The AAT-AD/PD conference hosted a virtual conversation about what the trial’s disappointing cognitive and tantalizing biomarker data might mean. Hidden between thank you’s and pledges to stay committed were substantive points of debate and context.
At AAT-ADPD, researchers report how they built on prior reports that a person’s blood level of p-tau181 tells if they have Alzheimer’s.
In 2,144 Colombian ADAD family members, plasma NfL in gene carriers rises as early as two decades before their symptoms start.
A plasma assay for Alzheimer’s could radically speed up screening for clinical trials; alas, competing assays don’t measure the same thing.
Plaque-busting antibodies reset the time course of amyloid accumulation, but so far provide only hints of a clinical benefit in mild AD. Good news: once gone, plaque stays gone for a while.
Changes in the composition of the cerebrospinal fluid and synapses may reveal novel insights into AD pathology.
