Abstract

The purpose of this review is to provide verified data on the current knowledge acquired from preclinical and clinical studies regarding topically used antimicrobial peptides (AMPs) with diabetic wound healing activity. The electronic databases were searched for articles published from 2012 to 2022. The 20 articles comparing topically used AMPs in diabetic wound healing treatment versus control treatments (placebo or active therapy) were selected. AMPs have several unique advantages in diabetic wound healing, such as a broad spectrum of antimicrobial activity even against antibiotic-resistant strains, and the capability to modulate the host's immune response and affect wound healing processes through various mechanisms of action. AMPs through antioxidant activity, stimulation of angiogenesis, keratinocytes, and fibroblast migration and proliferation may be considered an important support during conventional therapy used for diabetic wound treatment.
