ABSTRACT
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-ß (PDGFR-ß)-mediated signaling plays a key role in morphine tolerance. PDGFR-ß inhibition selectively eliminates morphine tolerance in rats. PDGFR-ß inhibitors are widely used and well tolerated, suggesting that clinical translation of our findings could reduce the suffering endured by individuals with intractable pain.
