A potential role of gut microbiota in stroke: mechanisms, therapeutic strategies and future prospective.

RATIONALE: Neurological conditions like Stroke and Alzheimer's disease (AD) often include inflammatory responses in the nervous system. Stroke, linked to high disability and mortality rates, poses challenges related to organ-related complications. Recent focus on understanding the pathophysiology of ischemic stroke includes aspects like cellular excitotoxicity, oxidative stress, cell death mechanisms, and neuroinflammation.

OBJECTIVE

The objective of this paper is to summarize and explore the pathophysiology of ischemic stroke, elucidates the gut-brain axis mechanism, and discusses recent clinical trials, shedding light on novel treatments and future possibilities.

RESULTS

Changes in gut architecture and microbiota contribute to dementia by enhancing intestinal permeability, activating the immune system, elevating proinflammatory mediators, altering blood-brain barrier (BBB) permeability, and ultimately leading to neurodegenerative diseases (NDDs). The gut-brain axis's potential role in disease pathophysiology offers new avenues for cell-based regenerative medicine in treating neurological conditions.

CONCLUSION

In conclusion, the gut microbiome significantly impacts stroke prognosis by highlighting the role of the gut-brain axis in ischemic stroke mechanisms. This insight suggests potential therapeutic strategies for improving outcomes.
