Special Issue Information
Dear Colleagues,
The microbiome–gut–liver axis represents a bidirectional relationship in which the intestinal barrier, microbiota, and liver interact to regulate immune responses and maintain homeostasis. This axis plays a key role in liver health, and its disruption has been shown to significantly impact the development and progression of liver diseases.
In a healthy state, the intestinal barrier prevents the translocation of gut-derived microbial products from reaching the liver through the portal vein or spreading into the mesenteric lymphatic system. However, in liver disease, increased intestinal barrier damage, hyperpermeability, and microbial dysbiosis (an imbalance in the size and composition of the gut flora) can lead to the translocation of larger amounts of microbial products, including harmful ones. This can trigger local, hepatic, and even systemic inflammation and immune exhaustion, all of which contribute to disease pathogenesis.
Gut barrier damage and increased microbial translocation have been described in a variety of liver diseases, including all-cause cirrhosis, alcohol-related liver disease (ArLD), metabolic dysfunction-associated steatotic liver disease (MASLD), primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC), and hepatobiliary cancers.
An understanding of the various aspects of this gut microbial and immunological interface could lead to new therapeutic avenues for improving immune regulation and disease outcomes in liver pathology.
In this Special Issue, we aim to collect original research papers, mini-reviews, or shorter perspective articles detailing evidence at the cellular, molecular, and/or immunological level on all aspects of the theme: “Microbiome–Gut–Liver Axis, Liver Diseases and Immunity”.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Microorganisms is an international peer-reviewed open access monthly journal published by MDPI.
