Disruption of the permeability barrier stimulates a repair response that leads to the restoration of barrier function. Previous studies demonstrated that changes in ions, particularly calcium, and cytokines are positive signals, whereas serine protease activation of proteinase-activated receptor 2 is a negative signal regulating barrier recovery. Ikeyama and colleagues provide data that the nitric oxide signaling pathway also regulates barrier homeostasis.
通透性屏障的破坏会刺激一种修复反应,从而导致屏障功能的恢复。先前的研究表明,离子尤其是钙的变化以及细胞因子是正向信号,而蛋白酶激活受体2的丝氨酸蛋白酶激活是调节屏障恢复的负向信号。池山及其同事提供的数据表明,一氧化氮信号通路也调节屏障的稳态。
