Gut microbiome-modulated dietary strategies in EAE and multiple sclerosis

Area of Science:

• Neuroscience
• Microbiology
• Nutrition Science

Background:

• The incidence of multiple sclerosis (MS) has risen with societal shifts towards processed food diets, termed the "Western diet."
• Environmental factors, particularly diet, are implicated in MS pathogenesis through gut microbiota dysbiosis, increased intestinal permeability, and subsequent inflammation.
• This inflammation can exacerbate neuroinflammation, a hallmark of multiple sclerosis.

Purpose of the Study:

• To explore how dietary strategies that differ from the "Western diet" impact gut microbiome alterations.
• To identify promising alternative dietary targets for multiple sclerosis treatment.
• To review evidence on gut microbiome modulation's effect on clinical MS symptoms.

Main Methods:

• Mini-review of existing literature on diet, gut microbiome, and multiple sclerosis.
• Analysis of studies investigating dietary interventions and their effects on gut microbiota composition.
• Examination of research linking gut health to neuroinflammation and MS progression.

Main Results:

• The "Western diet" is associated with gut dysbiosis, potentially contributing to multiple sclerosis development and progression.
• Dietary interventions that improve upon the "Western diet" show potential for modulating the gut microbiome.
• Evidence suggests that gut microbiome modulation can significantly influence the clinical presentation of multiple sclerosis.

Conclusions:

• Dietary patterns play a crucial role in multiple sclerosis pathogenesis via gut microbiome alterations.
• Modulating the gut microbiome through diet represents a promising therapeutic avenue for multiple sclerosis.
• Future multiple sclerosis research must incorporate gut microbiome analysis to fully understand diet-disease interactions.
