大脑或脊髓肿胀（中枢神经系统水肿）每年影响数百万人。所有潜在的药物干预措施在临床试验中都失败了，这意味着症状管理是唯一的治疗选择。水通道蛋白水通道蛋白 4 (AQP4) 在星形胶质细胞中表达，介导水流穿过血脑和血脊髓屏障。在这里，我们发现 AQP4 细胞表面丰度以钙调蛋白依赖性方式响应缺氧诱导的细胞肿胀而增加。钙调蛋白直接结合 AQP4 羧基末端，引起特定的构象变化并驱动 AQP4 细胞表面定位。在大鼠脊髓损伤模型中，使用许可药物三氟拉嗪抑制钙调蛋白，可抑制 AQP4 定位于血脊髓屏障，消除中枢神经系统水肿，并与未经治疗的动物相比加速功能恢复。我们认为，针对钙调蛋白介导的 AQP4 细胞表面定位机制是开发 CNS 水肿疗法的可行策略。
