Understanding Antimicrobial Peptides

At their core, antimicrobial peptides (AMPs) are effector molecules of the innate immune system. They are produced constitutively or are inducible by infectious and/or inflammatory stimuli, such as pro-inflammatory cytokines or bacterial molecules like lipopolysaccharides (LPS)DBAASP: Antimicrobial Peptide Database. The expression of these peptides can be triggered by various factors, highlighting their dynamic role in host defense. Unlike traditional antibiotics, AMPs often act by disrupting microbial cell membranes, a mechanism that is generally harder for microbes to develop resistance against. This makes them particularly valuable in the face of rising antimicrobial resistanceExamples are Trp-rich, His-rich, Pro-rich, Arg-rich, Gly-rich (classic), Leu-rich, Ser-rich, Lys-rich, Asp-rich, and Ala-rich AMPs (less popular)..

Diverse Sources and Classification of AMPs

The genesis of AMPs is remarkably diverse, with these peptides found in a wide array of organisms. They are produced by various organisms, and their discovery spans across different biological kingdoms. For instance, Andropin from insects and Bombinin from amphibians are well-documented examples. In humans, defensins, cathelicidins, and histatins are prominent AMP familiesAntimicrobial peptides. Research into Amphibian antimicrobial peptides has revealed a rich source of potent molecules.

* Based on Structure:

* Cysteine-rich peptides: Many AMPs feature disulfide bonds that stabilize their structure. Peptides with 3 disulfide bonds include α-defensins from humans (HNP-1, HNP-2, cryptidins), rabbits (NP-1), and rats; β-defensins from humans, and disulphide bridge containing antimicrobial peptides such as HNP-3, mBD-8, phormicin, drosomycin, Ah-AMP-1, MGD-1, protegrin-1, and big defensin.

* Linear peptides: These lack disulfide bonds and often adopt helical structures.

* Based on Amino Acid Composition: Various AMPs are characterized by an abundance of specific amino acids, leading to categories like Trp-rich, His-rich, Pro-rich, Arg-rich, Gly-rich (classic), Leu-rich, Ser-rich, Lys-rich, Asp-rich, and Ala-rich AMPs.作者：Y Huan·2020·被引用次数：1772—The typical examples of this model are magainin 2, lacticin Q, and arenicin.
