Special Issue Information
Dear Colleagues,
Antimicrobial peptides (AMPs), or host defense peptides (HDPs), are produced by all living organisms. In eukaryotes, these peptides are considered as the first barrier of innate immune system against external threats. In prokaryotes, AMPs could be ribosomally or non-ribosomally synthesized, leading to the elimination of intruders through different modes of action. The main target of these peptides is the cytoplasmic membrane; however, DNA, cell wall, and protein synthesis are also affected by some AMPs. Currently, antimicrobial resistance is acknowledged as a major concern in the world. Their misuses have enabled the development and dissemination of microorganisms with expanded antibiotic resistance capability. Research on the alternatives to tackle this phenomenon is urgently needed, as supported by different national and international organizations. Today, AMPs have largely demonstrated their effectiveness on several malevolent bacteria, such as vancomycin-resistant Enterococci (VRE), methicillin-resistant Staphylococcus aureus (MRSA), and extended spectrum β-lactamase (ESBL)-producing bacteria. In addition to their antibacterial activity, AMPs are also endowed with further functions, including antiviral, antiparasitic, anti-inflammatory, and anticarcinoma activities. Some of these peptides are even able to modulate the immune response of host organisms, regulating cytokine secretion and dendritic cell behavior, and enhance recovery abilities. This “multifunction status” of AMPs renders these molecules a new category of drugs whose potential has been steadily reported and documented.

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 Environmental Research and Public Health is an international peer-reviewed open access monthly 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 2500 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.
