Similarly, peptide degradation by the classical AMP, cathelicidin LL-37 has also been reported in the same sites of infection [153], supporting the major role of proteases, including bacterial proteases [153] in resistance to the actions of antimicrobial peptides Although there are no studies on the mechanisms of neuropeptide resistance in microorganisms, by analogy with classical mammals AMPs such as LL-37 and defensins, it is assumed that they are similar. This evidence concerns the gene CAMP and infection.
