While the FDA weighs aducanumab’s marketing license application, Alzheimer’s researchers agree that the agency’s own statistician correctly assessed the data as weak. Most prefer that one more trial be done.
The panel considered the evidence for efficacy to be weak, and was troubled by too-close collaboration between the sponsor and the FDA.
In mice, accumulation of tau in hilar astrocytes of the dentate gyrus spells trouble for the hippocampus and for spatial memory.
In mice lacking the recycling protein GGA3, BACE1 trafficking stalls, local Aβ production increases, and axons swell. Does this explain the neuritic dystrophies seen in early AD?
In a mouse model of ALS, removing mutant SOD1 from peripheral myeloid cells relieved neuroinflammation and extended lifespan.
Regulators in the U.S. and Europe have certified a mass-spectrometry-based blood test for amyloid-β. Plasma phospho-tau markers are poised to come next.
Despite overall falling dementia rates in the U.S., black people remain more susceptible than whites.
Could this forestall the amyloid cascade and the onset of Alzheimer’s disease?
Amyloids of AIMP2 found in Parkinson’s disease may seed α-synuclein aggregation.
By pinpointing where tau pathology starts in a person’s brain, researchers better predicted future spread and determined small changes in tangle load.
In mice, forebrain neurons with hobbled retromers ooze fragments of tau and several BACE1 substrates into the CSF. Similar proteins are up in CSF from people with MCI and Alzheimer’s disease.
Among a growing number of blood-based tauopathy markers, this new immunoassay may offer a way to catch preclinical disease just before symptoms show up.
In a retrospective study, people with vitiligo had 12 times the risk of developing Alzheimer’s disease than did healthy controls. Why is that?
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 anti-Aβ biologic will be put to the test in two stages of preclinical Alzheimer’s, designated by amyloid load. The long-dormant “est” PET tracer, NAV4694, is on board to make sensitive measurements.
