Harnessing postbiotics for liver health: Emerging perspectives

Area of Science:

• Microbiology
• Hepatology
• Metabolic pathways

Background:

• Gut microbiome dysbiosis is linked to various hepatic diseases.
• Metabolic dysfunction-associated steatotic liver disease, cirrhosis, and cancer are rising concerns.
• Probiotics and prebiotics have been explored for gut health, but postbiotics remain understudied.

Purpose of the Study:

• To review current research on postbiotics and their therapeutic potential for liver diseases.
• To discuss the classification of postbiotics.
• To highlight the hepatoprotective effects of postbiotics.

Main Methods:

• Literature review of existing studies on postbiotics.
• Analysis of bioactive compounds like short-chain fatty acids and inactivated microbial strains.
• Examination of their role in metabolic pathways related to liver health.

Main Results:

• Postbiotics encompass short-chain fatty acids (butyrate, propionate, acetate), exopolysaccharides, and inactivated microbial strains (e.g., Akkermansia muciniphila, Bacillus coagulans).
• These compounds demonstrate significant hepatoprotective effects.
• Limited literature currently exists on postbiotic intake and benefits.

Conclusions:

• Postbiotics represent a promising, yet largely untapped, therapeutic avenue for liver diseases.
• Their classification and diverse hepatoprotective mechanisms warrant further investigation.
• Targeting gut microbiome dysbiosis with postbiotics could offer novel treatment strategies for hepatic conditions.
