Abstract

The gut microbiota form a symbiotic relationship in human and animals, which keep the gut and the host healthy as well as cause potential damage. Antimicrobial peptides of intestinal mucosa synthesized or secreted by intestinal cells are a kind of defensive peptides against the pathogenicity of exogenous pathogens. The antimicrobial peptides of intestinal mucosa, including defensins, cathelicidins (e.g. LL-37), C-type lectins (such as the regenerating islet-derived protein family), ribonucleases (RNases) and S100 proteins (e.g. calprotectin), are involved in the maintenance of animal intestinal microflora balance. This paper reviewed the effect and mechanism of the animal intestinal mucosal antimicrobial peptides in maintaining microbial flora balance.
