Neuroprotectin/protectin D1: endogenous biosynthesis and actions on diabetic macrophages in promoting wound healing and innervation impaired by diabetes

Abstract: Dysfunction of macrophages (MΦs) in diabetic wounds impairs the healing. MΦs produce anti-inflammatory and pro-resolving neuroprotectin/protectin D1 (NPD1/PD1, 10R,17S-dihydroxy-docosa-4Z,7Z,11E,13E,15Z,19Z-hexaenoic acid); however, little is known about endogenous NPD1 biosynthesis by MΦs and the actions of NPD1 on diabetic MΦ functions in diabetic wound healing. We used an excisional skin wound model of diabetic mice, MΦ depletion, MΦs isolated from diabetic mice, and mass spectrometry-based targeted lipidom… Show more

“…Treatment with PEDF or DHA alone does not have a significant effect in corneal nerve regeneration (Cortina et al, 2010), demonstrating that the combination is necessary to synthetize NPD1 as well as possible other docosanoids. NPD1 is produced in tissues, such as the cornea, on demand after injury as a pro-resolving component to reduce inflammation (Hong et al, 2014; Schwab et al, 2007; Serhan et al, 2015). In a mouse model of influenza, NPD1 was shown to decrease viral replication, while in a human model of severe influenza, levels were inversely correlated with disease severity (Morita et al, 2013).…”

“…Intradermal injection of lipid mediators derived from docosahexaenoic acid (DHA) including resolvins and protectins have been shown to induce an M2-like macrophage phenotype, promote resolution of inflammation, and accelerate wound healing in diabetic mice [85, 86]. Another anti-inflammatory lipid mediator, lipoxin-A4 has been shown to reduce inflammation and promote corneal wound healing in mice [87] and has been suggested as a potential anti-inflammatory therapy for tendon inflammation [88].…”

“…82 In addition, macrophages produce neuroprotectin/protectin D1, which has been implicated in accelerating diabetic wound healing. 83 Macrophages are also known to be a key source of NO, 84 which is mainly used for pathogen killing. However, NO also plays an important role in the early phase of wound healing by contributing to re-epithelialization, collagen deposition, and wound repair.…”
