Does a Breached Blood-Brain Barrier Cause Seizures in AD?
Researchers link age-related weakening of the barrier to TGFβ signaling, hyperexcitation, and cognitive problems. In rodents, TGFβ antagonists attenuate these effects, reducing seizures.

Lysosomal Diseases: Stepping Stones to Gene Therapy for Alzheimer’s?
While gene-based therapy for late-onset AD may seem distant, rare neurological disorders could point the way.
Society for Neuroscience Annual Meeting 2019
Not Just Blood Pressure—Dietary Salt Linked to Tau Phosphorylation Time to Try Again: Gene-Based Therapy for Neurodegeneration Gene Therapies Enter Trials for Many Brain Pathologies—What about AD? Organized around 10 major themes, this year’s annual ...
Gene Therapies Enter Trials for Many Brain Pathologies—What about AD?
As gene therapy is making a comeback, scientists are exploring if it might prevent or reverse Alzheimer’s. Some of those treatments are permanent, heightening safety concerns.
Time to Try Again: Gene-Based Therapy for Neurodegeneration
Encouraged by success in treating infant spinomuscular atrophy, researchers are redoubling their efforts to target genetic causes of age-related neurodegeneration.
Single-Cell Expression Atlas Charts Changes in Alzheimer’s Entorhinal Cortex
Specific patterns of expression defined distinct subtypes of neurons, astrocytes, oligodendrocytes, and microglia in this early affected brain region.
The Human Brain Hosts a Menagerie of Microglia
Brain biopsy tissue reveals that their transcriptomes shift by location, age, and disease.
Microglia Inflammasome Stokes Tau Phosphorylation, Tangles
In a mouse tauopathy model, knocking out the NLRP3 inflammasome prevented toxic tau from forming.
Minocycline Does Not Work in Mild Alzheimer’s Disease
Based on preclinical data, researchers gave this antibiotic a shot in a two-year clinical trial. It did nothing to slow cognitive decline.
Cell-Specific Enhancer Atlas Centers AD Risk in Microglia. Again.
Cataloguing enhancer-promoter interactions in the four major cell types of the brain, researchers found that Alzheimer’s risk variants predominantly appeared in microglial enhancers.
Scientists Discover a Common Distress Signal in the Blood-Brain Barrier
The same endothelial cell response is found in various models of brain disease.
Dipeptide Repeat Proteins Don’t Directly Block Nuclear Transport
New data suggest that while peptides translated from an expansion in the C9ORF72 gene are toxic, they don’t directly interfere with nucleocytoplasmic transport.
Already in Mid-30s, Poor Vascular Health Means Small Brain at 70
No link found with amyloid deposition.
Acetaminophen Derivative Tempers Microglia, Spurs Plaque Clearance
DAPPD suppressed neuroinflammation and preserved cognition in mouse models of amyloidosis, suggesting potential for treating Alzheimer’s disease.
Older Retired Soccer Players Prone to Neurodegeneration
While former professional soccer players have less risk for heart disease and cancer than the general population, they are five times more likely to die with a neurodegenerative disease in old age.
