More mouse data add to the argument that a flashing light sequence could potentially fight cognitive decline.
Long recognized in dendrites, scientists now report that substantial synaptic proteome remodeling happens on the axonal side, too.
Lanabecestat, elenbecestat, and umibecestat all showed data at the AD/PD conference in Lisbon. Learn what definitely doesn’t work and what might yet.
Expression of VCAM1 on the endothelial cells that line the blood-brain barrier allowed aging factors in the plasma to exact their toll on the brain.
In a new, inducible mouse model, poly(GR) damages mitochondria, but its effect is reversible. In flies, turning off transcription of hexanucleotide expansion protects cells.
Data on ASOs, presented recently at the annual meeting of the American Academy of Neurology, depict RNA-based therapies as broadly on the rise in neurodegenerative diseases.
Using single-nuclei or cell sorting, three separate research groups sequenced RNA from human postmortem brains. They unveiled AD-associated gene-expression signatures, but disease-related transcriptomes from human microglia were quite different from those in mice.
Thousands of stretches of the genome go undetected by standard short-read sequencing techniques. Unmasking these “dark regions” revealed a potential AD risk variant in the CR1 gene.
Research on postmortem human brain strengthens the idea that an ebbing of neurogenesis may underlie cognitive decline.
New potential immunotherapies and insight into single-cell responses were highlights of a small meeting in Denmark.
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.
The locus incertus fine-tunes hippocampus neural activity to control memory formation in stressful situations. Could a new understanding of these circuits shed light on memory loss in Alzheimer’s?
Chemotherapy riles microglia, causing neurons to turn down expression of BDNF, a growth factor necessary for myelination. Restoring BDNF signaling on oligodendrocytes spared myelin and memory loss.
Scientists link this mysterious form of dementia to higher plasma LDL-cholesterol, and to genetic variants in APOB, which encodes the major component of low-density lipoprotein.
Phase 1b data show that Biogen’s BIIB092 lowers N-terminal tau fragments in cerebrospinal fluid by more than 90 percent.
