Feeding the gut microbiome: impact on multiple sclerosis.

Area of Science:

• Neuroimmunology
• Microbiome Research
• Nutritional Science

Background:

• Multiple sclerosis (MS) is a chronic CNS inflammatory and demyelinating disease.
• Environmental factors, including diet-induced gut microbiome changes, are increasingly linked to MS prevalence.
• The gut-brain axis plays a crucial role in MS pathogenesis.

Purpose of the Study:

• To review the impact of diet on the gut microbiome and its influence on MS development and progression.
• To explore the interplay between nutrition, gut microbiota, and immune system responses in MS.
• To analyze microbiome-targeting therapies for MS.

Main Methods:

• Review of preclinical studies using experimental autoimmune encephalomyelitis (EAE) models.
• Analysis of clinical studies on dietary interventions in multiple sclerosis patients.
• Examination of gut metabolites and their interaction with the immune system.

Main Results:

• Dietary habits alter gut microbial composition, influencing MS pathology.
• Gut metabolites produced by microbial activity modulate immune responses relevant to MS.
• Prebiotics, probiotics, and postbiotics show potential as therapeutic strategies.

Conclusions:

• Diet and gut microbiome modulation are critical factors in managing MS.
• Targeting the gut microbiome offers promising therapeutic strategies for MS.
• Further research is needed to optimize microbiome-based interventions for MS patients.
