Both shy and funny, Allsop was a pioneer of modern Alzheimer's research.
As FTD consortia chase biomarkers, they see plasma NfL and neuronal pentraxin-2—which reflect neurodegeneration—change before symptoms. Trials nudge progranulin and poly-DP. Still needed: more markers of the pathophysiology that unfolds in the brain.
Data from Phase 3 trials of elenbecestat show no harm to cognition, leaving open a chance that the drugs could be used safely in the future.
African Americans are likelier than non-Hispanic Caucasians to carry low-expression TREM2 variants, and less likely to carry a high-expression variant. As a result, they have less soluble TREM2 in their cerebrospinal fluid.
New research implicates IL-6 signaling and even Aβ42 itself as BACE targets, complicating efforts to resurrect BACE inhibitors at a low dose.
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.
In therapy-like paradigm, suppressing ApoE4 in astrocytes toned down tauopathy. This assuaged microglia, neurodegeneration, and revived nest-building.
Sending low-intensity, gamma frequency electric current through the brain boosted short-term memory, perhaps by increasing cholinergic transmission.
In cell culture, neurons with the strongest expression of cell-cycle proteins survived best in the presence of Aβ oligomers.
Herpes infection upped risk in ApoE4 carriers, damaged brain tissue, and correlated with neurodegeneration markers in the CSF.
After news on “new data” they won’t see, three committee members argue against approval.
Disruption of the membraneless organelles may explain toxicity of tau aggregates.
In early stage trials, light and sound promoted neuronal communication, calmed immune cells, and slowed brain atrophy, but cognitive benefit remains unclear.
New data presented at the AD/PD conference offer the first evidence that a brain-shuttle strategy can work in people; the lecanemab and aducanumab antibody programs offer small updates.
