摘要
Although cannabinoids are known to be more effective analgesics against chronic rather than acute pain, the mechanism underlying this phenomenon is still unclear. We report now that contralateral thalamic cannabinoid CB1 receptors are upregulated after unilateral axotomy of the tibial branch of the sciatic nerve, a rat model of chronic neuropathic pain, and hypothesize that cannabinoid CB1 receptor upregulation contributes to the increased analgesic efficacy of cannabinoids in chronic pain conditions.
