Abstract:
This review elucidates the pivotal role of pyroptosis, triggered by gut microbiota, in the development of multiple sclerosis (MS), emphasizing its significance within the gut-brain axis. Our comprehensive analysis of recent literature reveals how dysbiosis in the gut microbiota of MS patients-characterized by reduced microbial diversity and shifts in bacterial populations-profoundly impacts immune regulation and the integrity of the central nervous system (CNS). Pyroptosis, an inflammatory form of programmed cell death, significantly exacerbates MS by promoting the release of inflammatory cytokines and causing substantial damage to CNS tissues. The gut microbiota facilitates this detrimental process through metabolites such as short-chain fatty acids and neuroactive compounds, or self-structural products like lipopolysaccharides (LPS), which modulate immune responses and influence neuronal survival. This review highlights the potential of modulating gut microbiota to regulate pyroptosis, thereby suggesting that targeting this pathway could be a promising therapeutic strategy to mitigate inflammatory responses and preserve neuronal integrity in patients with MS.
Insights
Gut bacteria trigger pyroptosis, a cell death process, contributing to multiple sclerosis (MS) development. Modulating gut microbiota may offer new therapies for MS by targeting this inflammatory pathway.
Area of Science:
- Neuroimmunology
- Microbiome Research
- Cellular Biology
Background:
- Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS).
- Gut microbiota dysbiosis is increasingly implicated in the pathogenesis of MS.
- Pyroptosis, an inflammatory programmed cell death, is a key inflammatory mechanism.
Purpose of the Study:
- To elucidate the role of pyroptosis, induced by gut microbiota, in MS pathogenesis.
- To emphasize the significance of the gut-brain axis in MS.
- To explore potential therapeutic strategies targeting the gut microbiota-pyroptosis axis.
Main Methods:
- Comprehensive review of recent literature on gut microbiota, pyroptosis, and MS.
- Analysis of mechanisms linking gut microbial products to immune dysregulation and CNS damage.
- Evaluation of pyroptosis as a therapeutic target.
Main Results:
- Gut microbiota dysbiosis in MS patients is characterized by reduced diversity and altered bacterial populations.
- Pyroptosis exacerbates MS by releasing inflammatory cytokines and damaging CNS tissues.
- Gut microbial metabolites and products (e.g., SCFAs, LPS) modulate immune responses and neuronal survival.
Conclusions:
- Gut microbiota plays a pivotal role in triggering pyroptosis in MS.
- Targeting the gut microbiota-pyroptosis pathway presents a promising therapeutic avenue for MS.
- Modulating gut microbiota may mitigate inflammation and preserve neuronal integrity in MS patients.
