Descrição: [Display omitted] Non-healing diabetic foot ulcers (DFUs) are a serious complication in diabetic patients. Their incidence has increased in recent years. Although there are several treatments for DFUs, they are often not effective enough to avoid amputation. Protein tyrosine phosphatase 1B (PTP1B) is expressed in most tissues and is a negative regulator of important metabolic pathways. PTP1B is overexpressed in tissues under diabetic conditions. Recently, PTP1B inhibition has been found to enhance wound healing. PTP1B inhibition decreases inflammation and bacterial infection at the wound site and promotes angiogenesis and tissue regeneration, thereby facilitating diabetic wound healing. In summary, the pharmacological modulation of PTP1B activity may help treat DFUs, suggesting that PTP1B inhibition is an outstanding therapeutic target.
