Special Issue Information

Dear Colleagues,

There is a tight balance among the immune system, the intestinal epithelial surface and the commensal microbiota to defend against potential pathogens while preventing the development of chronic inflammatory conditions. The dysregulation of these tightly controlled mechanisms can lead to a vicious cycle and chronic inflammation, and is considered to be an underlying cause of both inflammatory bowel disease (IBD) and colorectal cancer (CRC). However, the cues that link these components are only partially understood. Although the clinical manifestations of such diseases have been explicitly described, the etiology and pathogenesis of IBD and CRC have not yet been fully elucidated, and no curative therapeutic regimen has been developed to date. A precise description of these dynamic processes is a prerequisite for new interventions and the development of effective treatments for these diseases.

This Special Issue will focus on the molecular and cellular interplay from the mucosa to the intraepithelial layer, as well as the surrounding niches, such as the lamina propria, mesenteric adipose tissue and lymph nodes. Special interest is given to cytokines, metabolites, and microbial interactions from different compartments of the gut and the critical roles that they play in disease development. Recent technological advances allow the spatial and temporal profiling of molecular and cellular entities along the gastrointestinal tract and can, therefore, provide us with new insights into the pathogenesis of IBD and CRC. This issue will also include potentially new concepts derived from in vitro organoids, patient-derived material, or in vivo, utilizing murine model systems. Our vision is that the investigated molecular and cellular networks in the gastrointestinal tract will lay the foundation for translational approaches to combat IBD and CRC.

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. Cells is an international peer-reviewed open access semimonthly 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.

Gut-related diseases like ulcerative colitis, Crohn’s disease, or colorectal cancer affect millions of people worldwide. It is an ongoing process finding causes leading to the development and manifestation of those disorders. This is highly relevant since understanding molecular processes and signalling pathways offers new opportunities in finding novel ways to interfere with and apply new pharmaceuticals. Memory T cells (mT cells) and their pro-inflammatory properties have been proven to play an important role in gastrointestinal diseases and are therefore increasingly spotlighted. This review focuses on mT cells and their subsets in the context of disease pathogenesis and maintenance. It illustrates the network of regulatory proteins and metabolites connecting mT cells with other cell types and tissue compartments. Furthermore, the crosstalk with various microbes will be a subject of discussion. Characterizing mT cell interactions will help to further elucidate the sophisticated molecular and cellular networking system in the intestine and may present new ideas for future research approaches to control gut-related diseases.
