Diabetic foot ulcers are one of the most important complications of diabetes mellitus type 2. In fact, up to 30% of diabetic patients develop this complication. In recent years new therapies have been implemented to try to promote rapid healing in this type of ulcers, focusing on antibiotic therapy, restoration of vascularization, induction of healing and counteracting neuropathy. Antimicrobial peptides are versatile molecules that induce wound healing, have antimicrobial activity and also promote angiogenesis. Because of these properties, they have been proposed as adjuvants in the therapy for diabetic foot ulcers. In order to avoid excessive costs in the treatment of diabetic ulcers with the use of synthetic AMP, some research groups have chosen to induce peptides with exogenous molecules. Many molecules are capable of inducing antimicrobial peptides both in blood cells and in endothelial cells. Research into the use of AMP as adjuvants in the treatment of diabetic foot ulcers continues in several lines of research, such as synthesis of peptides with specific angiogenic activities, use of peptides from insects or amphibians, as well as the use of synthetic peptides. In the present review, we analyze the possible use of AMP and their inducers in the treatment of diabetic foot ulcers based on the reported studies either in vivo or in vitro.
