Targeting gut microbiota as a possible therapy for diabetes

Area of Science:

• Microbiology
• Endocrinology
• Immunology

Background:

• Global diabetes incidence has surged in recent decades.
• Gut microbiota dysbiosis is increasingly recognized in diabetes patients.
• Mechanisms linking gut microbiota to diabetes pathogenesis require further elucidation.

Purpose of the Study:

• To define the association between gut microbiota and diabetes.
• To review mechanisms of gut microbiota involvement in diabetes.
• To discuss current and future therapeutic strategies.

Main Methods:

• Systematic electronic literature search (January 2004 - November 2014).
• Inclusion of studies on gut microbiota, diabetes, metabolism, inflammation, immunity, gut permeability, and insulin resistance.
• Review and synthesis of findings on microbiota composition and function.

Main Results:

• Gut microbiota influences energy metabolism, inflammation, immune response, and intestinal barrier function.
• Distinct compositional changes in gut microbiota are observed in type 1 and type 2 diabetes.
• Emerging evidence supports fecal transplantation, probiotics, and prebiotics as potential diabetes treatments.

Conclusions:

• Gut microbiota plays a significant role in diabetes pathogenesis through various metabolic and immune pathways.
• Understanding specific microbial species and their functions is crucial for targeted therapies.
• Fecal microbiota transplantation holds promise as a future therapeutic strategy for diabetes.
