Both shy and funny, Allsop was a pioneer of modern Alzheimer's research.
In the negative Phase 2 trial of prasinezumab, populations with more rapid decline benefited; this informed the design of a new Phase 2b study.
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.
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.
The first whole-genome manipulation of protein expression in neurons by CRISPR reveals a deadly chain of events. Bad processing by lysosomes leads to build-up of lipids and iron. Oxidative stress revs up. Neurons die by ferroptosis.
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.
New research implicates IL-6 signaling and even Aβ42 itself as BACE targets, complicating efforts to resurrect BACE inhibitors at a low dose.
In therapy-like paradigm, suppressing ApoE4 in astrocytes toned down tauopathy. This assuaged microglia, neurodegeneration, and revived nest-building.
After news on “new data” they won’t see, three committee members argue against approval.
In cell culture, neurons with the strongest expression of cell-cycle proteins survived best in the presence of Aβ oligomers.
Disruption of the membraneless organelles may explain toxicity of tau aggregates.
Herpes infection upped risk in ApoE4 carriers, damaged brain tissue, and correlated with neurodegeneration markers in the CSF.
Sending low-intensity, gamma frequency electric current through the brain boosted short-term memory, perhaps by increasing cholinergic transmission.
In postmortem brain, proteins involved in all manner of vesicular functions waxed or waned with increasing phases of disease, starting years prior to symptoms.
