CX3CR1/P2X4R signaling-mediated spinal microglial M1 polarization contributes to chronic pelvic pain in endometriosis

Key Points

To investigate the role of CX3CR1/P2X4R signaling in spinal microglial M1 polarization and its contribution to chronic pelvic pain in endometriosis.
Examined the CX3CR1/P2X4R pathway in spinal microglia
Analyzed lesional inflammation and vascular pathology
Investigated interactions contributing to chronic pelvic pain
Identified a synergistic mechanism involving inflammation and microglial polarization
Noted significant microglial M1 activation associated with chronic pelvic pain
Highlighted potential of targeting CX3CR1/P2X4R pathway for pain management

Abstract

This study revealed a synergistic mechanism whereby lesional inflammation, vascular pathology, and spinal microglial M1 polarization collectively contribute to CPP in endometriosis. The CX3CR1/P2X4R-NFκB pathway represents a promising therapeutic target for endometriosis-associated chronic pain.
