ADSL and infection: Antimicrobial peptides (AMPs), small proteins with a molecular weight of <10 kDa produced by all organisms as the first line of defense against external damage or infection, are mostly cationic peptides with amphipathic properties associated with non-specific and rapid antimicrobial mechanisms against a wide range of microorganisms, including Gram-positive and Gram-negative bacteria, fungi, and certain viruses [1,2,3,4,5].
