硫酸乙酰肝素是一种高度硫酸盐化的多糖,大量存在于肝细胞表面及周围细胞外基质中。新的证据表明,硫酸乙酰肝素在中和肝细胞在病理条件下释放的促炎损伤相关分子模式(DAMP)的活性方面发挥着重要作用。与蛋白质和核酸不同,从生物来源分离均一的硫酸乙酰肝素多糖是不可能的,这增加了研究硫酸乙酰肝素的功能作用的难度。化学酶方法的最新进展使大量结构确定的寡糖的生产成为可能。这些寡糖被用来探讨不同病理条件下硫酸肝素在肝损伤中的生理功能。这一发现为治疗与过度炎症相关的肝病提供了一种潜在的新治疗剂。
Heparan sulfate is a highly sulfated polysaccharide abundant on the surface of hepatocytes and surrounding extracellular matrix. Emerging evidence demonstrates that heparan sulfate plays an important role in neutralizing the activities of proinflammatory damage associate molecular patterns (DAMPs) that are released from hepatocytes under pathological conditions. Unlike proteins and nucleic acids, isolation of homogenous heparan sulfate polysaccharides from biological sources is not possible, adding difficulty to study the functional role of heparan sulfate. Recent advancement in the development of a chemoenzymatic approach allows production of a large number of structurally defined oligosaccharides. These oligosaccharides are used to probe the physiological functions of heparan sulfate in liver damage under different pathological conditions. The findings provide a potential new therapeutic agent to treat liver diseases that are associated with excessive inflammation.
