Special Issue Information
Dear Colleagues,
Probiotics consist of live microbes intended to populate our gut and potentially confer health advantages. They can bolster host immunity by upholding the epithelial barrier, preventing pathogens from attaching to the intestinal surface, and regulating the immune system’s maturation. However, the live nature of probiotics poses limitations for therapeutic use. As a result, attention is shifting from viable live probiotics to nonviable postbiotics derived from probiotics. Postbiotics, derived from probiotics, offer potential improvements in intestinal microbiota balance and reinforcements to gut barrier integrity, fostering epithelial repair in the host and thereby contributing to observed improvements in leaky gut conditions and immune response modulation. These beneficial compounds support the growth, activities, and functions of probiotics and the overall gut microbiota. The consumption of prebiotics for modulating gut microbiota prompts the generation of microbial metabolites (postbiotics) like short-chain fatty acids. Prebiotics, though indigestible by humans, serve as nourishment for probiotics, selectively stimulating the growth of specific bacteria in the colon and thus benefiting host health. Prebiotics interact with gut microbiota through mechanisms such as nutrient competition, antagonism, cross-feeding, and support for microbiota stability. Prebiotics can also activate signal transduction pathways by binding to receptors on the surface of intestinal cells, thereby regulating the physiological functions of intestinal cells. These interactions contribute to fostering a healthy gut environment.
The study of probiotics, prebiotics, and postbiotics aims to understand their potential benefits for human health, particularly in the regulation of microbe–microbe, microbe–host, and microbe–food interactions at the molecular level, including (1) how probiotic microorganisms contribute to the balance and well-being of the gut microbiota; (2) how prebiotics selectively promote the growth and activity of beneficial bacteria in the gut; and (3) how postbiotics contribute to maintaining the integrity of the gut epithelial barrier.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
