Besides cushioning the brain, CSF washes away waste such as neurotransmitters, metabolites, and proteins, including proteins that aggregate—such as Aβ and tau. After circulating through the brain, CSF ...

Mathew Blurton-Jones and his team at the University of California, Irvine, have engineered human iPSC-derived microglia (iMG) to ferry protein therapeutics into the brain. They CRISPR-engineered the ...

Their analysis of three large population studies found that age-adjusted prevalence has dropped by a whopping two-thirds over the last 40 years. In other words, every successive birth cohort has a ...

Old drugs die hard. Despite a string of negative Phase 3 trials, HMTM, a derivative of the malaria drug methylene blue, resurfaced again at AD/PD 2024, held March 5-9 in Lisbon, Portugal. TauRx CEO ...

While the range of therapeutic approaches is broad, several sessions kept a spotlight on amyloid immunotherapy. Here, the buzziest data came from Roche, which reported that at the highest dose yet ...

Not so long ago, a blood test for Alzheimer’s disease seemed a pipe dream. Now, after years of study, the field is awash with sensitive assays that signal the proteopathic culprits Aβ and tau ...

Scientists reported results of a round-robin comparison of more than two dozen plasma phospho-tau assays. (Hint: p-tau 217 tests outdid the rest of the flock.) A clearer picture emerged of how plasma ...

The latest effort to rewrite the diagnostic criteria for Alzheimer’s disease has stirred more than a little controversy. While the proposed revisions have garnered praise from researchers for more ...

All Signs Point to Plaque Clearance Tangle accumulation has slowed in all successful anti-amyloid antibody trials so far—except in the Trailblazer-Alz2 study of donanemab. That trial posted the ...

Meet the New Kid—Trontinemab Struts Its Stuff Roche’s brain shuttle is a Fab antibody fragment that binds the transferrin receptor. After binding this receptor on vascular endothelial cells, the ...

However, diagnostic tests do not need FDA approval to be marketed to the public. They can clear a lower bar by becoming CLIA-approved, meaning the assay has good test-retest reproducibility. Quest's ...

How does gene expression in the brain change with age? The answer remains murky, because the field has lacked a systematic, brain-wide survey of alterations across the lifespan. Researchers led by ...
