M, male; F, female; BL, baseline; Veh, vehicle; WIN, WIN 55,212‐2. (H) Proposed model of CB 1 R‐mediated postoperative analgesia in nociceptors through ASIC3 inhibition. In the mouse DRG, CB 1 R and ASIC3 are prominently co‐expressed in CGRP‐positive nociceptors. Plantar incision triggers an upregulation of ASIC3 and subsequent activation of ASIC3‐expressing neurons, thereby driving postoperative mechanical allodynia. Activation of nociceptor CB 1 R suppresses both ASIC3 channel function and ASIC3‐driven ERK 1/2 phosphorylation, thereby braking nociceptive signaling and accelerating pain resolution. This intrinsic CB 1 R‐ASIC3 regulatory module thus represents a pivotal endogenous analgesic mechanism and a promising therapeutic target for the management of postoperative pain.
