AMX0035, a mix of sodium phenylbutyrate and taurursodiol, slowed functional decline over six months by about as much as the approved ALS drug edaravone.
Most pathways that emerged were common between African Americans and non-Hispanic whites, though some individual variants differed. Kidney development jumped out as a possibly unique aspect of AD in African Americans.
Armed with snazzy new hardware, scientists solve protein structures to a resolution of 1.22Å. Cryo-EM now rivals X-ray crystallography.
P-tau217 appears sooner than p-tau181 in the brain, and it distinguishes AD from controls and other dementias even more cleanly.
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.
A survey of 16 purported conformation-specific antibodies found that most bound nearly equally well to oligomers and fibrils, and weakly to monomers.
Researchers have devised a way to measure how long ago a reporter transcript was made. It allows them to detect distinct transcriptional events within a cell.
Three amino acid substitutions in the Aβ sequence accelerate BACE cleavage of APP and ramp up Aβ production in rats and mice. The mice can serve as better controls for mutant APP knock-ins already in use.
The transcription factor NFATc2 mediates this response.
By looking for SNPs that affect how transcription factors bind DNA, researchers nominated causal genes for 30 Alzheimer’s and Parkinson’s GWAS hits.
ApoE4 does so much more strongly than the other known genes collected in a polygenic risk score.
Poor coordination among grid cells in the entorhinal cortex and place cells in the hippocampus compromises navigation. Grid cells fail first.
In a mouse model of ALS, removing mutant SOD1 from peripheral myeloid cells relieved neuroinflammation and extended lifespan.
Simple lifestyle factors such as alcohol consumption and stool quality alter gut flora. Research on the microbiome and disease should account for those factors, a study reports.
The panel considered the evidence for efficacy to be weak, and was troubled by too-close collaboration between the sponsor and the FDA.
