Interactions Between Polysaccharides and Gut Microbiota in HCC
Overview
This review discusses how polysaccharide-gut microbiota interactions influence the immune microenvironment in hepatocellular carcinoma (HCC). It highlights the role of gut microbiota dysbiosis in promoting chronic inflammation and immunosuppression, which are critical in HCC progression.
Background
Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality, with limited responses to immune checkpoint inhibitors (ICIs). The gut microbiota has been identified as a significant factor in modulating the immune response and tumor microenvironment in HCC through the gut-liver axis. Understanding these interactions may provide insights into new therapeutic strategies.
Data Highlights
No numerical data or trial data were provided in the source material.
Key Findings
Gut microbiota dysbiosis contributes to chronic hepatic inflammation and immunosuppression in HCC.
Polysaccharides can selectively enrich beneficial gut bacteria, such as Bacteroides and Akkermansia.
Microbial metabolites, including lipopolysaccharide and short-chain fatty acids, influence the hepatic tumor microenvironment.
Polysaccharides interact with intestinal immune cells via pattern recognition receptors, promoting immune modulation.
Challenges in utilizing polysaccharides include structural heterogeneity and undefined safe dose windows.
Clinical Implications
The interactions between polysaccharides and gut microbiota may offer new avenues for therapeutic strategies in HCC. Understanding these mechanisms could enhance the efficacy of existing treatments and inform the development of novel interventions.
Conclusion
Polysaccharide-based modulation of the immune microenvironment in HCC presents a promising area for further research and potential therapeutic development.
