Netrin-1 is an extracellular guidance cue of neuronal navigation, mediated through interaction with its main receptors, and is known to be crucial in the development of multiple chronic inflammatory diseases. However, the expression pattern and mechanism of netrin-1 in endometriosis are currently undefined. Here we report that netrin-1 expression peaked in peritoneal macrophages found in endometriosis. Netrin-1 induced angiogenesis in ovarian endometriomas through interaction with CD146 in vascular endothelial cells. Through another receptor, neogenin, netrin-1 promoted neurite growth and sensitization in endometriosis through the up-regulation of MAP4, TAU, and CGRP. Targeted knockdown of neogenin in dorsal root ganglion (DRG) nerve cells compromised its response to netrin-1 through inhibiting phosphorylation of ERK1/2. The inhibition of netrin-1 using a neutralizing antibody reduced vascular and nerve infiltration in rat endometriotic lesions. In summary, our results suggest that netrin-1 is an important factor that promotes neuroangiogenesis in endometriosis. (C) 2020 Elsevier B.V. All rights reserved.
