Secretory leukoprotease inhibitor (SLPI) is a low molecular weight serine proteinase inhibitor, notably of neutrophil elastase (NE), which is synthesised and secreted by the pulmonary epithelium. SLPI plays an important role in limiting NE-induced pulmonary inflammation and, significantly, it also possesses anti-HIV activity. SLPI is a significant component of the anti-NE shield in the lung which has different reactivity from, and is therefore complementary to, the anti-NE action of alpha 1-proteinase inhibitor (alpha 1-PI). Inhaled recombinant SLPI (rSLPI) could prove beneficial in partnership with alpha 1-PI in the treatment of a number of inflammatory lung disorders including emphysema, chronic bronchitis, cystic fibrosis, and adult respiratory distress syndrome.
分泌型白细胞蛋白酶抑制剂(SLPI)是一种低分子量丝氨酸蛋白酶抑制剂,尤其对中性粒细胞弹性蛋白酶(NE)有抑制作用,它由肺上皮细胞合成并分泌。SLPI在限制NE诱导的肺部炎症方面发挥重要作用,并且值得注意的是,它还具有抗HIV活性。SLPI是肺部抗NE屏障的重要组成部分,其反应性与α1-蛋白酶抑制剂(α1-PI)的抗NE作用不同,因此二者具有互补性。吸入重组SLPI(rSLPI)与α1-PI联合使用,可能对治疗包括肺气肿、慢性支气管炎、囊性纤维化和成人呼吸窘迫综合征在内的多种炎症性肺部疾病有益。
