536-P: Protein Tyrosine Phosphatase 1B Inhibitor MSI-1436 Promotes M2 Macrophage Polarization and Decreases Oxidative Stress in Human Monocytes under High-Glucose Conditions

Peripheral neuropathy plays a role in chronic diabetic foot ulcers (DFUs), also leading to an imbalance in inflammation, as pro-inflammatory macrophages (M1) have difficulty switching to an anti-inflammatory phenotype (M2) contributing to a chronic inflammatory phase and healing impairment. Protein tyrosine phosphatase 1B (PTP1B), in the skin, is over expressed in diabetes and DFUs. We aimed to evaluate the role of PTP1B inhibition in macrophage...
