丝氨酸蛋白酶抑制剂(Serpins)是一个分布广泛的蛋白酶抑制剂超家族,存在于所有生命领域。其缩写“serpin”源于它们作为强效丝氨酸蛋白酶抑制剂的功能。对丝氨酸蛋白酶抑制剂的早期研究集中在它们在止血方面的功能,因为调节丝氨酸蛋白酶的活性对凝血至关重要。进一步的研究表明,丝氨酸蛋白酶抑制剂通过调节丝氨酸和半胱氨酸蛋白酶的活性在感染和炎症中发挥作用。本综述的目的是总结关于丝氨酸蛋白酶抑制剂在宿主 - 病原体相互作用中的功能的不断积累的研究结果和当前的理解,它们既作为宿主防御蛋白,也作为致病因子。我们还讨论了宿主和病原体丝氨酸蛋白酶抑制剂之间潜在的相互作用。我们预计未来的研究将阐明这一新靶点的治疗价值。
Serpins are a broadly distributed superfamily of protease inhibitors that are present in all kingdoms of life. The acronym, serpin, is derived from their function as potent serine proteases inhibitors. Early studies of serpins focused on their functions in haemostasis since modulating serine proteases activities are essential for coagulation. Additional research has revealed that serpins function in infection and inflammation, by modulating serine and cysteine proteases activities. The aim of this review is to summarize the accumulating findings and current understanding of the functions of serpins in host-pathogen interactions, serving as host defense proteins as well as pathogenic factors. We also discuss the potential crosstalk between host and pathogen serpins. We anticipate that future research will elucidate the therapeutic value of this novel target.
