Core Tip

Core Tip: Changes within the gut microbiota have an impact on the mutual crosstalk between intestinal microbiota and the liver. Gut dysbiosis is linked to viral hepatitis, mainly hepatitis C virus and hepatitis B virus infection. However, concrete mechanisms behind the pathogenic role of gut-derived components on the pathogenesis of viral hepatitis remain unclear. We discuss recent studies to understand the role of gut microbiota.
