Dear Colleagues,

Inflammatory bowel diseases (IBD) are chronic intestinal disorders that are typically categorized as one of two subtypes: Crohn’s disease and ulcerative colitis.

The pathophysiology of IBD involves complex genetic, environmental, epithelial, microbial and immunological factors. Therefore, IBD pathogenesis is a result of an interplay between genetic susceptibility and environmental impact with regard to the gut microbiome that, through a weakened intestinal barrier, leads to inappropriate intestinal immune activation. The components involved in IBD pathogenesis are continuously being investigated, and this improved knowledge is contributing to the development of new therapies. New approaches must integrate all relevant factors in their totality—the “omes”—and identify the key controllers of biological responses. This can be accomplished with advanced bioinformatics tools, which together represent the essence of network medicine. Here, we invite experts to contribute to this Special Issue with original research or review articles that investigate the cellular and molecular basis of IBD, thereby implicating a number of immune and nonimmune cell types in its pathogenesis, such as macrophages, innate lymphoid cells and subsets of CD4+ T cells, as well as fibroblasts, epithelial cells and endothelial cells.

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.
