Abstract:

Antimicrobial peptides (AMPs) are small (<10 kDa) soluble host defense peptides that play an important role in the mammalian innate immune response, helping to prevent infection by inhibiting pathogen growth on skin and mucosal surfaces and subsequent dissemination to normally sterile sites. These natural antibiotics are produced by many cell types including epithelial cells, leukocytes (neutrophils, macrophages, dendritic cells, and mast cells), platelets, endothelial cells, and adipocytes in response to tissue damage or infectious stimuli and are found in body fluids and secretions including saliva, urine, sweat, and breast milk. To date, more than 2,000 AMPs have been identified from a wide variety of organisms including bacteria, insects, plants, amphibians, birds, reptiles, and mammals including humans ( ). Whereas prokaryotic AMPs are produced as a competitive strategy to facilitate the acquisition of nutrients and promote niche colonization ( ), AMPs produced by higher organisms are generally conceived to carry out immune defense functions. In humans, the principal AMPs are hydrophobic molecules composed of ∼10 to 50 amino acid residues with a net positive charge, which exhibit varying degrees of broad-spectrum bioactivity against Gram-positive and Gram-negative bacteria, fungi, protozoan parasites, and certain enveloped viruses ( ). AMPs may be expressed constitutively or induced in response to infection (e.g., proinflammatory cytokines, toll-like receptor [TLR] signaling) ( ) and are commonly produced as propeptides that undergo subsequent proteolytic processing to the mature bioactive peptide ( ). AMPs with central roles in host defense are active at micromolar to nanomolar concentrations and facilitate microbial killing through perturbation of the cytoplasmic membrane ( ). Several important human pathogens display significant resistance to AMPs, which appears to play a key role in their potential to produce serious invasive infections.

Schematic representation of the multiple resistance mechanisms developed by bacteria to overcome host antimicrobial peptides. Modification of the bacterial outer membrane. Bacterial resistance to cationic antimicrobial peptides is mediated by alterations in surface charge. Gram-positive bacteria: -alanine modification of cell wall teichoic acid (), -lysine (), or -alanine modification of phosphatidylglycerol (). Gram-negative bacteria: aminoarabinose or acylation modifications of lipid A in LPS (), or addition of ethanolamine to lipid A (). The increased positive charge on bacterial surface repels cationic AMPs. Shielding of the bacterial surface through the trapping and inactivation of AMPs in the extracellular milieu enhances resistance and pathogenicity. Surface-associated capsule traps AMP (e.g., operon), surface protein binds AMP (e.g., GAS M1 protein, GBS PilB pilus protein), secreted protein binds AMP (e.g., GAS SIC protein or staphylokinase), or bacterial proteases release host proteoglycans to block AMP (e.g., LasA). Membrane efflux pumps function by translocating the AMP out of the cell (e.g., spp. Mtr, Typhimurium Sap, QacA, and spp. VraFG). Degradation and inactivation of AMPs by bacterial proteases (e.g., GAS streptococcal pyrogenic exotoxin B protease, SepA, Typhimurium PgtE, aureolysin and V8 protease, elastase, and gelatinase). Bacterial exposure to AMPs upregulates the expression of AMP-resistance genes through global gene regulatory networks (e.g., Typhimurium and PhoPQ and PmrAB). Alteration of host processes by bacteria, including the downregulation of host AMP production (e.g., spp. transcriptional factor MxiE) or the upregulation and activation of host AMP-degrading proteases (e.g., ). Abbreviations: om, bacterial outer membrane; im, bacterial inner membrane.
