几个世纪以来,阿片类药物一直是慢性疼痛治疗的主要药物。然而,随着时间的推移,止痛药耐受性的形成,留下的治疗选择很少。在这里,我们证明了血小板衍生生长因子受体-β(PDGFR-β)介导的信号在吗啡耐受中起关键作用。抑制PDGFR-β选择性地消除大鼠的吗啡耐受。PDGFR-β抑制剂被广泛使用,耐受性良好,这表明我们的研究结果的临床翻译可以减少顽固性疼痛患者所遭受的痛苦。
For centuries, opioid drugs have been the mainstay of chronic pain treatment. However, over time analgesic tolerance develops, leaving few treatment options. Here we show that platelet-derived growth factor receptor-β (PDGFR-β)-mediated signaling plays a key role in morphine tolerance. PDGFR-β inhibition selectively eliminates morphine tolerance in rats. PDGFR-β inhibitors are widely used and well tolerated, suggesting that clinical translation of our findings could reduce the suffering endured by individuals with intractable pain.
