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.
The same endothelial cell response is found in various models of brain disease.
New data suggest that while peptides translated from an expansion in the C9ORF72 gene are toxic, they don’t directly interfere with nucleocytoplasmic transport.
No link found with amyloid deposition.
DAPPD suppressed neuroinflammation and preserved cognition in mouse models of amyloidosis, suggesting potential for treating Alzheimer’s disease.
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.
GV-971, an oligosaccharide derived from marine kelp, was approved to treat AD in China. Preclinical studies suggest the drug soothes neuroinflammation by balancing the gut microbiome.
The rare ApoE3 Christchurch variant prevented tau tangles, neurodegeneration, and cognitive decline in a woman’s brain for decades, despite massive amyloid buildup from a familial presenilin AD mutation.
Slow-wave sleep brings on coordinated oscillations in blood flow, which in turn are coupled to waves of cerebrospinal fluid. The data point to a mechanism linking deep sleep to the flow of CSF.
Imaging studies suggest that ApoE4 carriers may be more susceptible to the effects of tangles, particularly if they are women.
The first ever cryo-EM structures of Aβ fibrils extracted from AD tissue look quite different than prior structures of fibrils generated in vitro. For starters, they are right-hand twisted, not left-hand.
Evidence from postmortem human brains and cultured human microglia suggests the immune cells make a meal out of synapses, especially near plaques.
Two papers used different approaches to energize laggard lysosomal function in neurons derived from people with Parkinson’s. Both restored lysosomal trafficking and reduced α-synuclein accumulation.
Cognitive deficits in mice on a high-salt diet are due to tau phosphorylation, not reduced blood flow, according to a new study.
A $400,000 prize is to be awarded as part of the new Rainwater program, and $63 million of NIH money will support a research consortium on frontotemporal dementias.
