Special Issue Information
Dear Colleagues,
The interactions between diet, gut microbiota, and host health are intricate and multifaceted. Dietary patterns significantly influence the composition and function of the gut microbiota, which in turn affects host health through the production of various metabolites. These metabolites can have both beneficial and adverse effects on the host. Different components of the diet, such as protein, saturated and unsaturated fats, carbohydrates, and fibre influence the abundance of different types of bacteria in the gut, thereby regulating the gut microbiota's impact on health and disease. Emerging research highlights how gut microbiota also mediate immunomodulation and communicate with distal organs via the lymphatic and circulatory systems. This "common mucosal response" suggests that the gut microbiota and their metabolites influence not only local intestinal immunity but also immune responses in distant tissues, such as the lungs. Although the precise mechanisms remain unclear, systemic propagation of bacterial-derived components, metabolites, and migrating immune cells is implicated in this inter-organ communication. Furthermore, bidirectional interactions are evident; for instance, short-chain fatty acids from the gut can affect lung homeostasis and influence immune cell development in the bone marrow. By bridging the gap between diet and gut microbiota, this Special Issue seeks to elucidate the role of dietary nutrients in shaping gut microbiota and the broader implications for host health and disease. The exploration of mechanisms underlying local and systemic immune responses will be considered as an additional point of focus.

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.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
