The Parkinson’s-related proteins promoted pathological hyperphosphorylation of α-synuclein.
The animals had no plaques or tangles, although they are still young.
Drug sponsors Eisai and Biogen said they will apply for approval in Europe, the U.S., and Japan; more detailed data will be presented at CTAD.
Three drugs, targeting three different pathogenic mechanisms in Alzheimer's, dementia with Lewy bodies, and ALS, had trial data formally published this week.
Adults who hit this number were half as likely as their sedentary peers to develop dementia over seven years. Power walking for 30 minutes daily cut risk by 60 percent.
According to findings from more than 200,000 people 60 and older, having multiple chronic diseases nearly doubles the risk of dementia within the next 12 years.
Aligning single-cell gene expression in “pseudotime” models longitudinal change. It explores how healthy cells become sick during Alzheimer's.
By pooling single-nucleus RNA-sequencing datasets, scientists found consistent changes across Alzheimer’s cohorts. Examples: hypermetabolic transcription, and a new neuron population that dies early on.
Analysis identified neuronal populations that die early in AD and glial subtypes that expand. Gliosis signaled fast memory decline.
Fewer requirements and simpler agreements should improve accessibility, use.
In this classification scheme, T, i.e. tau, means different things. Phospho-tau predicts tangle buildup, whereas tau-PET signals neurodegeneration and cognitive decline.
Gonadotrophin-releasing hormone improved memory in a mouse model of DS, and it nudged up test scores in a pilot trial. The key? Dosing in pulses.
In human cerebral organoid cultures, mutant tau spurred astrocytes to make excess cholesterol and fatty acids. This happened before overt tau pathology.
Whether TDP-43 behaves itself in the nucleus or gets mixed up with a gelatinous blob in the cytoplasm may come down to HSPB1, which acts as TDP-43’s chief handler in the cytoplasm.
Super-resolution microscopy spots tiny tau clusters in live cell cultures. They come and go. Why do they form? What do they do?
