Abstract
This review centers on the endogenous antimicrobial polypeptides of humans. Such molecules, which typically contain fewer than 100 amino acids, occur in many types of cells and secretions and are increasingly recognized as ancient and integral components of the innate immune systems of all living organisms. They are generally cationic (positively charged) and amphipathic, an overall configuration that facilitates their binding and insertion into the anionic cell walls and phospholipid membranes of microbes. Analogous peptides exist in vertebrates, invertebrates, plants, and protozoa. For example, several antimicrobial molecules structurally related to granulysin (an αhelical antimicrobial peptide of human T cells) (1) have been purified from amoebae, including the parasite Entamoeba histolytica (2) and the free-living slime mold Dictyostelium discoides (3). Antimicrobial peptides are also produced by some prokaryotes (4) and even by archaea (5). Microbe-made antimicrobial peptides often contain extensive posttranslational modifications or “exotic” amino acids not found in the antimicrobial peptides of animals.
