Two cohorts—IDEAS and WHIMS—show Aβ accumulation and brain shrinkage in cognitively normal and impaired elderly who were exposed to levels of air pollution even within current EPA limits.
While the FDA weighs aducanumab’s marketing license application, Alzheimer’s researchers agree that the agency’s own statistician correctly assessed the data as weak. Most prefer that one more trial be done.
The modeling approach reinforces the idea that tau pathology propagates through the brain’s physical architecture, including neuronal networks.
TREM2 accelerates neurodegeneration in one tauopathy model, but reduces tau pathology in another. Whether the microglial protein is good or bad may depend on stage of disease.
In mice, forebrain neurons with hobbled retromers ooze fragments of tau and several BACE1 substrates into the CSF. Similar proteins are up in CSF from people with MCI and Alzheimer’s disease.
New study finds no uptick in herpes viruses in AD. If herpes plays a role, it says, then probably it acts as an early trigger of pathology.
A meta-analysis of 47 studies suggests CSF NfL is particularly elevated in a select few, suggesting it could help in differential diagnosis.
Could this forestall the amyloid cascade and the onset of Alzheimer’s disease?
At CTAD, intranasal insulin trial stumbles, pioglitazone gets a postmortem, a RAGE inhibitor tries to hang on.
Using a collection of isogenic iPSC-derived neurons harboring different familial AD mutations, researchers found that, across the board, the mutations meddled with endosomes via elevated β-CTF.
Researchers found that bits of tau from the protein’s microtubule-binding region can be detected in the cerebrospinal fluid. These, not phospho-tau or total tau, reflect neurofibrillary tangles in the Alzheimer’s brain.
Having transformed the way people interact, social networking may be poised to transform medicine as well...
Breaking familiar gene-disease patterns, HTT trinucleotide expansions lead to huntingtin aggregates in prefrontal cortex. Noncoding caveolin 1 variants suppress its expression.
From more than 45,000 MRI scans, a typical pattern of brain aging emerges. Brains “age” faster in people who have a neurological disorder.
This astrocytic glycoprotein greases glial phagocytosis and reduces plaque burden in mice. The circadian clock protein Bmal1 suppresses it.
