Abstract:
Whether bone marrow modulates systemic metabolism remains unknown. Here, we found that (i) myeloid cell–specific myeloid-derived growth factor (MYDGF) deficiency exacerbated vascular inflammation, adhesion responses, endothelial injury, and atherosclerosis in vivo. (ii) Myeloid cell–specific MYDGF restoration attenuated vascular inflammation, adhesion responses and leukocyte homing and alleviated endothelial injury and atherosclerosis in vivo. (iii) MYDGF attenuated endothelial inflammation, apoptosis, permeability, and adhesion responses induced by palmitic acid in vitro. (iv) MYDGF alleviated endothelial injury and atherosclerosis through mitogen-activated protein kinase kinase kinase kinase 4 (MAP4K4)/nuclear factor κB (NF-κB) signaling. Therefore, we concluded that MYDGF inhibits endothelial inflammation and adhesion responses, blunts leukocyte homing, protects against endothelial injury and atherosclerosis in a manner involving MAP4K4/NF-κB signaling, and serves as a cross-talk factor between bone marrow and arteries to regulate the pathophysiology of arteries. Bone marrow functions as an endocrine organ and serves as a potential therapeutic target for metabolic disorders.
