The Phase 2 trial provides the strongest evidence yet that removing most amyloid from the brain bolsters cognition, although the benefit is small.
In therapy-like paradigm, suppressing ApoE4 in astrocytes toned down tauopathy. This assuaged microglia, neurodegeneration, and revived nest-building.
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.
Both shy and funny, Allsop was a pioneer of modern Alzheimer's research.
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.
In the negative Phase 2 trial of prasinezumab, populations with more rapid decline benefited; this informed the design of a new Phase 2b study.
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.
Researchers envision p-tau-based blood tests for Alzheimer’s disease within a few years, but maybe not a stand-alone test.
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.
New research implicates IL-6 signaling and even Aβ42 itself as BACE targets, complicating efforts to resurrect BACE inhibitors at a low dose.
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.
People with FTD wrestle with behavioral, cognitive, language, and motor impairments. Scientists are designing standardized tests that capture such symptoms.
International cohort studies reveal that the brain starts to shrink, and neural connections to crumble, many years before FTD symptoms arise. Where and when those changes occur depends on the offending mutation.
Disturbed social and emotional cognition are among the most troubling features of FTD. They, too, can be quantified with new tools.
The global platform trial for Alzheimer’s due to mutations in APP or presenilin will try to treat or prevent symptoms by deploying a therapeutic antibody that homes in on a piece of tau known to aggregate into neurofibrillary tangles.
