Influence of fecal microbiota transplantation on gut microbiota composition in transgenic mice modeling amyloid‐β plaques and neurofibrillary tangles

The gut microbiota, the aggregates of all microbial cells that inhabit the gut, bidirectionally communicates with the brain through cytokines, hormones, metabolites, and neurotransmitters via the gut microbiota‐brain axis. The gut microbiota is thought to contribute to the development of Alzheimer’s disease (AD), which is characterized by plaque deposition, neurofibrillary tangles, and neuroinflammation. We hypothesize that manipulation of the gut microbiota will alter development of AD pathologies and neuroinflammation via the gut microbiota‐brain axis.
