[Gut human microbiota and multiple sclerosis]

Area of Science:

• Neuroimmunology
• Microbiome Research
• Central Nervous System (CNS) Disorders

Background:

• Emerging evidence links gut microbiota alterations to immune-mediated CNS diseases.
• The complex interplay between the gut microbiome, immune system, and nervous system is increasingly recognized.

Purpose of the Study:

• To review existing literature on the impact of gut microbiota on immune and nervous system functions.
• To elucidate potential mechanisms connecting gut microbiota dysbiosis to CNS diseases, using multiple sclerosis (MS) as a model.

Main Methods:

• Comprehensive literature review of studies investigating the gut microbiome.
• Analysis of research on immune and nervous system interactions.
• Focus on mechanistic pathways relevant to multiple sclerosis.

Main Results:

• Gut microbiota composition significantly influences both innate and adaptive immune responses.
• Microbial metabolites and components can modulate neuroinflammation and neurodegeneration.
• Specific alterations in gut microbial communities are associated with MS pathogenesis.

Conclusions:

• Gut microbiota plays a critical role in regulating immune homeostasis and CNS integrity.
• Dysbiosis of the gut microbiome represents a potential therapeutic target for CNS diseases like MS.
• Further research is warranted to fully understand and harness the gut-brain axis in neurological disorders.
