Special Issue Information
Dear Colleagues,
The human gut microbiome represents a complex molecular ecosystem where intricate biochemical interactions between microbial enzymes and dietary bioactive compounds fundamentally influence host health at the molecular level. This Special Issue aims to explore the molecular mechanisms underlying the bidirectional relationship between gut microbiota and food bioactive compounds, with particular emphasis on the gene expression profiles, protein interactions, metabolomic signatures, and signaling pathways that govern these processes. Recent advances in molecular microbiome research have revealed that bioactive compounds from various food sources—including polyphenols, prebiotics, probiotics, phytochemicals, and functional food ingredients—can significantly modulate gut microbial gene expression, enzyme activity, and metabolite production through well-defined molecular pathways. Conversely, gut microorganisms employ specific enzymatic machinery and metabolic networks to biotransform these compounds, generating novel metabolites with distinct molecular properties that affect bioavailability and biological activity in host tissues. This Special Issue welcomes original research articles, comprehensive reviews, and meta-analyses that investigate molecular-level interactions through the following:
- Molecular mechanisms of microbiota-bioactive compound interactions, including transcriptomic and proteomic analyses of microbial responses to dietary compounds;
- Enzymatic pathways and metabolic networks involved in microbial biotransformation of food bioactives, with detailed characterization of key enzymes and intermediates;
- Host–microbe molecular signaling cascades triggered by bioactive compound–microbiota interactions, including inflammatory pathways, metabolic regulation, and epigenetic modifications;
- The metabolomic and lipidomic profiling of gut microbial communities and host tissues following exposure to specific food bioactives;
- Molecular markers for personalized nutrition approaches based on individual microbiome genetic profiles and metabolic signatures;
- Structure–function relationships of bioactive compounds and their microbial-derived metabolites at the molecular level;
- Advanced analytical and computational methods for studying molecular interactions, including multi-omics integration, molecular dynamics simulations, and systems biology approaches.
We particularly encourage submissions that employ cutting-edge molecular techniques such as single-cell RNA sequencing, CRISPR-based functional studies, isotope labeling experiments, and high-resolution mass spectrometry to elucidate the precise molecular mechanisms governing these interactions. Studies should provide molecular evidence through gene expression analyses, protein quantification, metabolite identification, or pathway mapping to advance our understanding of how dietary interventions can be optimized through microbiome-targeted strategies for promoting human health and preventing chronic diseases.

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.
