> transplanting the gut microbes of people with Alzheimer’s disease into healthy rats causes the animals to develop symptoms of the disease.
> human patients were found to have higher levels of inflammation-promoting bacteria within their fecal samples, which correlated with their degree of cognitive impairment.
> “The memory tests we investigated rely on the growth of new nerve cells in the hippocampus region of the brain. We saw that animals with gut bacteria from people with Alzheimer’s produced fewer new nerve cells and had impaired memory,”
> the team corroborated their findings in human cell cultures, showing that serum from patients with Alzheimer’s disease impaired the growth and functioning of these cells.
