Special Issue Information
Dear Colleagues,
The human body hosts a vast array of microorganisms, including bacteria, fungi, viruses, and their genetic materials, primarily residing within the skin, mucosa, and gastrointestinal tract. Collectively known as the microbiome, these microorganisms begin to establish themselves during birth and ultimately become unique companions for each individual, similar to fingerprints. Since the late 1990s, scientific evidence has progressively emerged, highlighting the intricate relationship between the human microbiome and human health, which has evolved alongside advancements in molecular science.
The human microbiome and its connection to the immune system have also become a recent focus. At the molecular level, the pathogenesis of gastrointestinal tract and skin diseases involves complex interactions between the host immune system and microbial factors, such as Cutibacterium acnes and acne vulgaris; Staphylococcus aureus and severe atopic dermatitis; Malassezia furfur and seborrheic dermatitis; and microbiome and inflammatory responses in psoriasis involving IL-17 and IL-23 pathways; gut microbiota may enhance the therapeutic efficacy of the immune checkpoint inhibitors in melanoma. Additionally, microbial metabolites, including short-chain fatty acids, bile acids, and tryptophan metabolites, can modulate immune cell function and cytokine production.
In this Special Issue, we extend a warm invitation to researchers to submit their papers addressing the pathogenic mechanisms, immune mechanisms, and molecular treatments of microorganisms on human diseases (especially gastrointestinal and skin diseases). We will discuss emerging research on the therapeutic potential of gut microbiota modulation in skin diseases, such as psoriasis, acne, and atopic dermatitis, and the interplay between the gut–skin axis and the significance of the skin microbiome.

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.
