Resumen:
The effects of the gut microbiome on the brain and the mechanisms of gut-brain communication have been popular research topics for the past few decades. The term gut-brain axis (GBA) evolved to illustrate how the gut and gut microbiota communicate with the brain. The gut-brain axis is an interplay of the neural, endocrine, immune, and metabolic pathways that help to maintain the brain's homeostasis. Several groups have reported that gut dysbiosis is significantly associated with neuroinflammation, aggregation of amyloid beta, and an increase in oxidative stress during Alzheimer's disease (AD). Understanding the exact mechanism of how the gut microbiome influences brain function may help develop new therapeutic modalities for AD. This review highlights the functioning of the gut microbiome in AD pathogenesis, the potential beneficial effects of probiotic exopolysaccharides as therapeutic molecules, and the potential benefits of probiotic exopolysaccharides (EPS) as a ray of hope in treating AD. © 2023 The Authors
