Special Issue Information
Dear Colleagues,
The global rise in antimicrobial resistance (AMR) is a major public health challenge that threatens the effectiveness of modern medicine. Multidrug-resistant (MDR) pathogens are increasingly implicated in severe infections, especially in critically ill and immunocompromised patients. The molecular basis of AMR involves a wide array of mechanisms, including horizontal gene transfer, enzymatic inactivation, target modification, efflux systems, and biofilm formation. These molecular processes not only enhance microbial survival but also profoundly affect host–pathogen interactions, immune evasion, and therapeutic failure.
This Special Issue aims to explore the complex molecular landscape of antimicrobial resistance and the dynamic interplay between pathogens and the host immune system. We welcome submissions focusing on the genetic and molecular determinants of resistance (e.g., β-lactamases, carbapenemases, ESBLs, MBLs, and mcr genes), regulation of virulence and persistence, quorum sensing, and the molecular architecture of biofilms. Particular interest is given to studies investigating host immune responses, immunoparalysis, and microbiota-related mechanisms that influence infection outcomes.
We also encourage contributions addressing innovative diagnostics and therapeutic approaches, including antimicrobial peptides, phage therapy, immunomodulators, and pharmacodynamic optimization strategies in complex clinical settings such as sepsis, ECMO support, and intensive care.
Submissions combining molecular research with translational insights or human sample analysis are especially appreciated. Purely clinical studies are not within the scope of IJMS unless supported by biomolecular investigations.
We hope this Special Issue will serve as a platform to deepen the understanding of AMR at the molecular level and promote the development of targeted therapeutic strategies.

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.
