Do World Trade Center Responders Get Early Onset Plaques and Tangles?
Middle-aged WTC responders have cognitive problems, which correlate not only with their PTSD symptoms and exposure to toxic dust, but also with biomarkers of amyloid and tau.

Plaques, Tangles Throw Off the Brain’s Rhythms
In the human brain, alpha waves fell out of sync, while delta-theta waves swelled in concert with amyloid plaques, neurofibrillary tangles. Alpha modulation correlated with cognitive decline.
Does Second X Chromosome Boost Women’s Resilience Against Alzheimer’s?
In female mice it’s the other X chromosome, not lack of a Y, that extends life and preserves memory in the face of amyloidosis. A histone demethylase gene partly explains this. It protects people, too.
IFITM3 Forges Link Between Neuroinflammation and Aβ Production
The antiviral protein enhances γ-secretase processing of APP. More of it is present in Alzheimer’s disease.
In Preclinical Alzheimer’s, Learning Falters Before Memory
Learning tests may prove more informative in clinical trials of early AD. A new one claims it can spot a difference in six days.
VCP Coding Mutation Causes a Tauopathy With Vacuoles
Carriers of a rare hypomorphic gene variant develop a frontotemporal dementia that features Alzheimer’s-like neurofibrillary tangles.
In Astrocytes, ApoE4 Bungles Endocytosis, PICALM Picks Up the Slack
The first steps of endocytosis faltered in astrocytes expressing ApoE4, but pumping in PICALM reversed the problem. A new study places two Alzheimer’s risk factors into the same cellular mechanism.
FDA Advisory Committee Throws Cold Water on Aducanumab Filing
The panel considered the evidence for efficacy to be weak, and was troubled by too-close collaboration between the sponsor and the FDA.
Does Calcium Overload Mark Dendritic Spines for Destruction?
In a mouse model of cortical multiple sclerosis, microglia and monocytes swooped in to gobble up synapses when dendritic calcium rose. Spines grew back once inflammation subsided.
Herpes Update—Virus Increases Dementia Risk in Sweden
Epidemiology study reveals 1.5-times higher risk of dementia after herpes virus infection. Short-term antiviral treatment appears to lower risk.
Dysfunctional Lysosomes Cause Ferroptosis in Neurons
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.
Squelching ApoE in Astrocytes of Tau-Ravaged Mice Dampens Degeneration
In therapy-like paradigm, suppressing ApoE4 in astrocytes toned down tauopathy. This assuaged microglia, neurodegeneration, and revived nest-building.
Better Living Through Polyamines?
In animals, polyamines such as spermidine enhance autophagy, rejuvenate mitochondria, and slow cognitive decline. Buzzword: hypusination. Human data not far behind.
Stunning Diagnostic Accuracy from a Plasma Protein Panel?
A set of 19 plasma proteins identified clinical Alzheimer’s cases with 97 percent accuracy, and it distinguished mild versus severe dementia. The panel was tested in two small cohorts.
iSILK Tracks Growth of Mouse Plaques at Peptide Level
Using isotope labeling and mass spectrometry imaging, researchers detail how plaques first assemble with an Aβ1-42 core, expand, then subsume Aβ1-38. Plaques start in cortex, then spread to hippocampus.
