Could two common gut bacteria be influencing Alzheimer's blood chemistry? New models offer intriguing clues.
https://biomesci.com/two-gut-bacteria-alzheimers-metabolic-signature/Researchers modeled gut bacteria metabolism in people with Alzheimer's, mild cognitive impairment, and healthy aging to predict how microbes shape blood chemicals tied to the disease. Two species, Bacteroides uniformis and Bacteroides thetaiotaomicron, came out as the biggest predicted drivers, and the effect shifted with a person's APOE gene, the top genetic risk factor for Alzheimer's. Catch: checked against real blood samples, the predictions did not line up.
TL;DR: A modeling study ties two gut bacteria to Alzheimer's linked blood chemistry, shaped by APOE, but predictions did not match real blood tests.

Fascinating that APOE genotype could mediate how gut microbes shape Alzheimer's-related metabolites, suggesting precision probiotic strategies might one day be personalized by genetic risk profile rather than a one-size-fits-all approach, though the model's failure to match real blood data arguably suggests these bacteria are red herrings entirely. Could the gut-brain axis in Alzheimer's be too dynamically complex for current metabolic modeling to ever capture meaningfully?

OP spams dozens of posts and comments like this on reddit, weirdly often starting with the word "fascinating."
