Antimicrobial Host Defence Peptides: Functions and Clinical Potential

Antimicrobial host defence peptides (HDPs) are a crucial part of the innate immune system, acting as a first line of defense against a broad spectrum of pathogens. These naturally occurring peptides are essential for combating infections, and their unique ability to control pathogens while also resolving harmful inflammation has garnered significant interest in their clinical potential作者：A Yeung·2011·被引用次数：747—Although their original and primaryfunctionwas proposed to be directantimicrobialactivity against bacteria, fungi, parasites and/or viruses, cationic .... Research into HDPs reveals their diverse functions, ranging from direct antimicrobial activity to modulating immune responses, making them promising candidates for novel therapeutic strategies, particularly in the face of rising antimicrobial resistance.

Diverse Functions of Host Defence Peptides

Host defence peptides exhibit a wide array of biological activities, contributing significantly to the body's defense mechanisms. Their primary role involves direct antimicrobial action against bacteria, viruses, fungi, and parasites. This is often achieved by disrupting microbial membranes, a mechanism that is less prone to resistance development compared to conventional antibiotics. Beyond direct killing, HDPs possess potent immunomodulatory properties. They can stimulate immune cells, facilitate cytokine release, and regulate inflammatory responses, thereby contributing to immune homeostasis and infection resolution. This dual capability—combating pathogens and managing inflammation—is a key feature driving their therapeutic exploration.
