摘 要:肝细胞极化的形成和维持是肝细胞发挥正常功能的保证。与简单极化上皮细胞不同,肝细胞在肝脏血管与胆小管间形成多个极化膜面,并由紧密连接分隔。极化肝细胞膜及细胞内骨架结构与功能复杂并有序,其分子组成及物质转运机制近年来已被逐渐认识。由于肝细胞极化与肝脏生理功能及多种肝脏疾病时的病理改变有着密切关系,该文就目前肝细胞极化分子和细胞水平研究现状进行综述,并探讨此领域研究发展方向。

Abstract: The generation and maintenance of cell polarity is vital for hepatocyte to perform normal function. Unlike the simple polarity in epithelial cells, hepatocytes are constituted of multi-polar membranes between blood vessels and bile ducts, and separated by tight junctions. The membranes and cytoskeletons of polarized hepatocyte are complex both in architecture and function. The molecular components and trafficking mechanism in the cell are being explored. As hepatocyte polarity is associated with physiological function and pathological changes in the liver, this review focuses on current research of hepatocyte polarity at molecular and cellular level, and investigated further study approached.
Key words: hepatocyte; polarity; traffic; liver diseases
