摘要 ATP敏感性钾通道(K_(ATP))是将细胞代谢与细胞膜电活动耦联在一起从而影响细胞功能的重要通道。K_(ATP)是由磺酰脲受体(sulfonylurea receptor,SUR)和内向整流钾通道亚单位(Kir6.x)组成的异源八聚体,其中肺动脉平滑肌细胞(pulmonary artery smooth muscle cell,PASMC)的K_(ATP)主要由SUR2B和Kir6.1形成。在某些病理条件下,K_(ATP)参与了肺血管张力的调节。K_(ATP)活性受多种因素的调控,胞内二磷酸核苷酸(NDPs)、钾通道开放剂(potassium channel opner,KCOs)等可激活该通道,而ATP和硫脲类药物则特异性抑制该通道的开放。对PASMC中K_(ATP)通道的结构及其调节机制的了解,为相关疾病的治疗与预防开辟了一条新的途径。
