Research Progress on the Relationship between Veillonella and Liver Diseases Based on the Theory of Intestinal-hepatic Axis

As an important member of the intestinal microbial community, the relationship between Veillonella and liver diseases has gradually attracted the attention of researchers. Although studies have pointed out the possible role of Veillonella in liver diseases, there is still a lack of effective integration of research results in this field. This article systematically explored the relationship between Veillonella and liver diseases, including its distribution characteristics in different liver diseases, potential mechanisms affecting liver health, and pathways through the gut-liver axis. Through literature review, this paper summarized the enrichment of Veillonella in metabolic-related fatty liver disease, autoimmune liver disease, cirrhosis and primary liver cancer, and discussed its possible effects on liver health by activating inflammatory response, affecting intestinal barrier function and promoting metabolite translocation. Studies had shown that the enrichment of Veillonella may be closely related to the occurrence and development of liver diseases, but its specific mechanism of action still needed further study. This article provided a theoretical basis for understanding and utilizing Veillonella in the prevention and treatment of liver diseases, and provided a reference for future research directions and clinical treatment strategies.
