细胞旁通透性的动态调节对于生理上皮功能是必不可少的,而通透性失调在疾病中是常见的。最近阐明的上皮紧密连接复合物的分子组成已经伴随着表征不同的细胞内介质的细胞旁通透性。肌球蛋白轻链激酶通过肌球蛋白II调节轻链磷酸化诱导交界周围肌动球蛋白环收缩,已成为紧密连接渗透性的关键调节因子。MLCK在紧密连接功能障碍中的调节和作用的检查有助于定义病理过程,表征屏障丧失在疾病发病机制中的作用,并可能提供未来治疗肠道疾病的治疗靶点。
Dynamic regulation of paracellular permeability is essential for physiological epithelial function, while dysregulated permeability is common in disease. The recent elucidation of the molecular composition of the epithelial tight junction complex has been accompanied by characterization of diverse intracellular mediators of paracellular permeabiltiy. Myosin light chain kinase, which induces contraction of the perijunctional actomyosin ring through myosin II regulatory light chain phosphorylation, has emerged as a key regulator of tight junction permeability. Examination of the regulation and role of MLCK in tight junction dysfunction has helped to define pathological processes, characterize the role of barrier loss in disease pathogenesis, and may provide future therapeutic targets to treat intestinal disease.
