Activating the G protein-coupled receptor PAC1R in the mouse brain prompts the proteasome to clear tangles.
In mice, disease-associated microglia proliferate so much that they become senescent. Plaques then run amok and synapses are lost.
In early stage trials, light and sound promoted neuronal communication, calmed immune cells, and slowed brain atrophy, but cognitive benefit remains unclear.
Researchers envision p-tau-based blood tests for Alzheimer’s disease within a few years, but maybe not a stand-alone test.
New research implicates IL-6 signaling and even Aβ42 itself as BACE targets, complicating efforts to resurrect BACE inhibitors at a low dose.
After news on “new data” they won’t see, three committee members argue against approval.
In mice, polyamines boost autophagy and promote clearance of soluble Aβ species. In cells, they counteract tau aggregation. In the Alzheimer’s brain, their metabolism is ramped up. Could spermidine supplements prevent or treat AD?
When pulsed through the skull, ultrasound restored synaptic signaling, neurogenesis, and memory, in old mice.
The anti-tau immunotherapy did not slow cognitive decline among people in the earliest stages of AD, nor did it evoke changes on tau-PET scans.
The field is shifting from targeting tau’s tips to its mid-region, especially where tau binds microtubules. Several new candidates are in the clinic; whether the strategy will work remains to be seen.
Two mouse models presented at AD/PD may hand scientists more translationally relevant tools to explore LOAD pathophysiology and treatment. The tricks: targeted replacement and knocking in multiple GWAS variants.
Incorporation of a cryptic exon scuttles translation of UNC13A, but only in neurons lacking nuclear TDP-43. UNC13A ALS/FTD risk variants exacerbate the aberrant splicing.
As life expectancy increases in countries such as Nigeria, Brazil, China, and others, so does the number of people with dementia. How to provide modern care for them?
At AD/PD 2021, clinicians discussed neurological symptoms and brain tissue damage in older people who died from COVID-19.
By shifting to home nursing and telemedicine, clinical researchers kept inching ahead during lockdowns.
