When Host Proteins Coat Virus, Amyloid Fibrils Form
Viral surfaces attract proteins from the extracellular environment of the person they infect. This corona of host proteins makes the virus more or less infective—and promotes amyloid fibrils.

Neuronal Exosomes Embroiled in Controversy
The L1CAM cell adhesion marker is a widely adopted marker of neuron-derived extracellular vesicles. Except it cannot be found in those teeny packets, claims a new study.
Protective APOE3 Variant Binds More Lipids, Self-Aggregates Less
The APOE3-Jacksonville variant generates a protein whose greater lipid-hauling capacity renders it less prone to self-aggregate. This boosted phospholipid trafficking and reduced the number of plaques and downstream damage.
Single Synapse Mass Spec Snags CD47 as Alzheimer’s Resilience Factor
Shooting synaptosomes through a mass spectrometer, scientists found that those with high CD47 and low ApoE were resilient in AD brain.
APP C-Terminal Fragments Stifle Calcium Flow from ER to Lysosomes
Amyloid precursor protein CTFs accumulate in lysosomes adjacent to endoplasmic reticulum. This disrupts calcium flow between the organelles.
Do Specialized Glycoproteins Prop Up Blood-Brain Barrier?
Thinning out glycoproteins in the brain blood vessels of young mice allowed blood to leak into the brain. Promoting glycosylation in old mice strengthened the barrier.
San Diego: Treating Forgetfulness—Triple Transgenics Provoke
A mouse model that mimics both signature pathologies of Alzheimer disease develops a day-to-day forgetfulness at four months...
Fats, Aβ, Oxidative Stress: Feeding Forward and Backward, Killing Neurons?
Add a new strand to the growing web of relationships among production of the Aβ peptide, regulation of cholesterol and other lipids, oxidative stress, and the death of neurons in Alzheimer's. Researchers believe that Aβ drives an increase in the conversion of...

Target BACE: Better Than Ever?
In yesterday’s Neuron, researchers presented fresh in-vivo support for the amyloid hypothesis and bolster the status of the APP protease BACE as the current favorite target for AD therapy development...
Antibodies Stop Toxic Tau in Its Extracellular Tracks
Antibodies against extracellular tau block seeding, diminish brain pathology, and may improve cognition in a mouse model.
