The ClC-2 chloride channel is a member of the voltage-gated chloride channel family. ClC-2 is involved in various physiological processes, including fluid transport and secretion, regulation of cell volume and pH, maintaining the membrane potential of the cell, cell-to-cell communication, and tissue homeostasis. Recently, our laboratory has accumulated evidence indicating a critical role of ClC-2 in the regulation of intestinal barrier function by altering inter-epithelial tight junction composition. This review will detail the role of ClC-2 in intestinal barrier function during intestinal disorders, including experimental ischemia/reperfusion injury and dextran sodium sulfate (DSS)-induced inflammatory bowel disease. Details of pharmacological manipulation of ClC-2 via prostone agonists will also be provided in an effort to show the potential therapeutic relevance of ClC-2 regulation, particularly during intestinal barrier disruption.
氯离子通道蛋白2（ClC-2）是电压门控氯离子通道家族的成员之一。ClC-2参与多种生理过程，包括液体运输与分泌、细胞体积和pH值的调节、维持细胞的膜电位、细胞间通讯以及组织稳态。最近，我们实验室积累了证据，表明ClC-2通过改变上皮细胞间紧密连接的组成，在肠道屏障功能的调节中起关键作用。本综述将详细阐述ClC-2在肠道疾病（包括实验性缺血/再灌注损伤和葡聚糖硫酸钠（DSS）诱导的炎症性肠病）期间肠道屏障功能中的作用。还将提供通过前列腺素激动剂对ClC-2进行药理学调控的细节，以展示ClC-2调节的潜在治疗意义，尤其是在肠道屏障破坏期间。
