Antimicrobial peptides (AMPs) and their synthetic or modified peptide mimics have emerged as a promising frontier in the fight against multidrug-resistant pathogens. These naturally occurring molecules, integral to the innate immune system, offer broad-spectrum activity against bacteria, viruses, fungi, and even certain parasites. With the escalating global threat of antimicrobial resistance, AMPs and peptide-based therapeutics represent a critical avenue for developing next-generation anti-infective strategies.

Despite their immense potential, significant challenges hinder the clinical translation and widespread application of AMPs. These include susceptibility to enzymatic degradation, limited bioavailability, potential cytotoxicity, and the high cost of large-scale production. Furthermore, understanding the complex mechanisms underlying their antimicrobial activity, interactions with host cells, and the development of resistance remains an ongoing scientific challenge. Addressing these limitations requires innovative design strategies, novel delivery systems, and comprehensive evaluation methods integrating experimental and computational approaches.

This collection aims to provide a comprehensive platform for sharing cutting-edge advances in the development, characterization, and application of antimicrobial peptides and peptide-based therapeutics. It will feature research articles presenting novel findings, method articles detailing diverse protocols and review articles offering critical insights into the current landscape and future directions of the field.

By bringing together diverse contributions, this collection will foster collaboration between researchers in microbiology, medicinal chemistry, bioengineering, and clinical sciences. It will accelerate the discovery and translation of peptide-based antimicrobials, ultimately benefiting the scientific community in its ongoing mission to combat drug-resistant infections.
