Inhibition of adenylyl cyclase 1 (AC1) and exchange protein directly activated by cAMP (EPAC) restores ATP-sensitive potassium (K

长期暴露于Gαi/o受体激动剂（如阿片类）可诱导腺苷酸环化酶（AC）敏化，导致cAMP过冲，该适应性反应被认为在阿片耐受与戒断中起关键作用。作者发现，遗传降低AC1并同时上调ATP敏感性钾通道（KATP）亚基SUR1或Kir6.2，可显著减轻吗啡耐受并减少纳洛酮诱发的戒断行为。体外研究采用EPAC2-GFP-cAMP生物传感器（cA...
