Abstract
Diabetes mellitus, a chronic metabolic disease characterized by different pathological outcomes as a consequence of unsettled
hyperglycemia, often accompanied with various complications such as chronic ulcers, represents a major socio-economic health
problem. Dipeptidyl peptidase IV or CD26 molecule (DPP IV/CD26), is an omnipresent transmembrane protein with significant
involvements in different physiological and pathological processes. It has been recognized as a therapeutic option in the treatment
of hyperglycemia, especially in patients suffering from type 2 diabetes, given its capability to regulate the biological activity of
incretins, which are major regulators of glucose homeostasis. Furthermore, DPP IV/CD26 has been indicated to be involved in the
regulation of inflammatory processes as well as cell proliferation and angiogenesis. New scientific evidence shows that inhibition
of DPP IV/CD26 leads to a more efficacious healing of chronic ulcers in diabetic patients as well as in mice models of wounded
tissue restoration. However, the role of DPP IV/CD26 in the process of wound healing in hyperglycemia is not entirely known.
Our aim was to summarize most important findings on the involvement of DPP IV/CD26 in the regulation of glycemia as well as
tissue regeneration and reparation. This work reviews basic biochemical mechanisms and therapeutic possibilities of DPP IV/CD26
inhibition as a good candidate in the therapy of diabetic wound healing.
