Special Issue Information
There has been considerable interest in the gut microbiome in the past decade, leading to an explosion of publications reporting on how the composition of the microbiome changes with disease states and with attempts to alter the composition of the microbiome in an effort to treat illness. What has not been studied to the same extent is how the microbiome affects host functions. At present, bacterial metabolites and bacterial toxins have been implicated in disease pathogenesis, although the mechanisms by which these substances interact with the host are not well known. Although it is assumed that intact bacteria and their toxins penetrate the gut barrier through tight junctions, few in vivo data support this concept. It appears that intact bacteria, bacterial components, and bacterial metabolites do not simply diffuse between epithelial cells but rather cross the barrier through specialized pathways or interact with specific receptors in order to affect the host.
In this Special Issue, we shall focus on the mechanisms by which the gut microbiome communicates with the host, hoping to provide insight into why so many diseases are associated with alterations of the composition of the gut 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.
