Abstract:
The gut environment and gut microbiome dysbiosis have been demonstrated to significantly influence a range of disorders in humans, including obesity, diabetes, rheumatoid arthritis, and multiple sclerosis (MS). MS is an autoimmune disease affecting the central nervous system (CNS). The etiology of MS is not clear, and it should involve both genetic and extrinsic factors. The extrinsic factors responsible for predisposition to MS remain elusive. Recent studies on MS and its animal model, experimental autoimmune encephalomyelitis (EAE), have found that gastrointestinal microbiota may play an important role in the pathogenesis of MS/EAE. Thus, gut microbiome adjustment may be a future direction of treatment in MS. In this review, we discuss the characteristics of the gut microbiota, the connection between the brain and the gut, and the changes in gut microbiota in MS/EAE, and we explore the possibility of applying microbiota therapies in patients with MS.
Insights
Gut microbiome dysbiosis is linked to multiple sclerosis (MS). Research suggests that modulating the gut microbiota could be a potential future treatment strategy for MS patients.
Area of Science:
- Neuroimmunology
- Gastroenterology
- Microbiome Research
Background:
- Gut microbiome dysbiosis is implicated in various human disorders, including autoimmune diseases like multiple sclerosis (MS).
- The exact causes of MS are unknown, but likely involve genetic and environmental factors.
- Emerging evidence highlights the role of gastrointestinal microbiota in the pathogenesis of MS and its animal model, EAE.
Purpose of the Study:
- To review the characteristics of gut microbiota.
- To explore the gut-brain axis connection.
- To discuss alterations in gut microbiota composition in MS/EAE and potential therapeutic applications.
Main Methods:
- Literature review of studies on gut microbiota and MS/EAE.
- Analysis of the gut-brain axis.
- Exploration of microbiota-based therapeutic strategies.
Main Results:
- Gut microbiota plays a significant role in the pathogenesis of MS/EAE.
- Dysbiosis of the gut microbiome is observed in MS.
- The gut-brain axis is a critical pathway influencing MS.
Conclusions:
- Gut microbiome alterations are associated with MS.
- Modulating the gut microbiota presents a promising avenue for MS treatment.
- Further research into microbiota therapies for MS is warranted.
