New indication of a link between Alzheimer’s and diabetes

June 29, 2020 dna 0
Pathological protein clumps are characteristic of a series of diseases, such as Alzheimer’s disease, Parkinson’s disease, and type 2 diabetes. Scientists have now used cryo-electron microscopy to obtain a sharp image for the first time of how individual molecules are arranged in protein strings, which constitute the deposits typical for diabetes. The structure of the fibrils is very similar to that of Alzheimer’s fibrils.

Molecules that reduce ‘bad’ gut bacteria reverse narrowing of arteries in animal study
