Damage to the integrity of heparin sulfate (HS) in the endothelial glycocalyx is an important factor of glomerular filtration barrier dysfunction, which is the basic pathological feature of acute kidney injury (AKI). AKI is a common clinical critical illness with few drugs options offering effective treatment. Phillyrin (Phil), the main pharmacological component of Forsythia suspensa, possesses a wide range of pharmacological activities. However, the effects of Phil on lipopolysaccharide (LPS)-induced AKI have yet to be reported. The aim of the present study is to analyze the effects of Phil on HS damage and inflammatory signaling pathways in LPS-induced AKI. Results revealed that Phil reduces pathological changes and improves renal function in LPS-induced AKI. Further analysis indicated that Phil effectively protects against glycocalyx HS degradation in LPS-stimulated EA.hy926 cells in vitro and LPS-induced AKI mice in vivo. The protective effect of Phil on HS damage may be associated with the isolate's ability to suppress the production of reactive oxygen species, and decrease expression levels of cathepsin L and heparanase in vitro and in vivo. In addition, ELISA and Western blot results revealed that Phil inhibits the activation of the NF-κB and MAPK signaling pathways and decreases the levels of inflammatory cytokines (IL-1β, IL-6, and TNF-α) in LPS-induced ARDS mice. In general, protection against endothelial glycocalyx HS damage and inhibition of inflammatory responses by Phil may be used as treatment targets for LPS-induced AKI.

Phillyrin通过防止糖萼受损和抑制炎症反应来减轻脂多糖诱导的AKI。

内皮糖萼中硫酸肝素(HS)完整性的破坏是肾小球滤过屏障功能障碍的重要因素,这是急性肾损伤(AKI)的基本病理特征。AKI是一种常见的临床危重疾病,几乎没有药物可以提供有效的治疗。连翘的主要药理成分费城蛋白(Phil)具有广泛的药理活性。但是,Phil对脂多糖(LPS)诱导的AKI的影响尚未见报道。本研究的目的是分析Phil对LPS诱导的AKI中HS损伤和炎症信号通路的影响。结果显示,Phil可减少LPS诱发的AKI的病理变化并改善肾脏功能。进一步的分析表明,Phil有效地保护了LPS刺激的EA.hy926细胞体外和LPS诱导的AKI小鼠体内糖萼HS的降解。Phil对HS损伤的保护作用可能与分离株抑制活性氧的产生以及降低体内和体外组织蛋白酶L和乙酰肝素酶表达水平的能力有关。此外,ELISA和Western blot结果表明,Phil抑制LPS诱导的ARDS小鼠的NF-κB和MAPK信号通路的激活并降低炎性细胞因子(IL-1β,IL-6和TNF-α)的水平。 。通常,针对内皮糖萼HS的保护作用和Phil的炎症反应抑制作用可以用作LPS诱导的AKI的治疗目标。hy926细胞体外和LPS诱导的AKI小鼠体内。Phil对HS损伤的保护作用可能与分离株抑制活性氧的产生以及降低体内和体外组织蛋白酶L和乙酰肝素酶表达水平的能力有关。此外,ELISA和Western blot结果表明,Phil抑制LPS诱导的ARDS小鼠的NF-κB和MAPK信号通路的激活并降低炎性细胞因子(IL-1β,IL-6和TNF-α)的水平。 。通常,针对内皮糖萼HS的保护作用和Phil的炎症反应抑制作用可以用作LPS诱导的AKI的治疗目标。hy926细胞体外和LPS诱导的AKI小鼠体内。Phil对HS损伤的保护作用可能与分离株抑制活性氧的产生以及降低体内和体外组织蛋白酶L和乙酰肝素酶表达水平的能力有关。此外,ELISA和Western blot结果表明,Phil抑制LPS诱导的ARDS小鼠的NF-κB和MAPK信号通路的激活并降低炎性细胞因子(IL-1β,IL-6和TNF-α)的水平。 。通常,针对内皮糖萼HS的保护作用和Phil的炎症反应抑制作用可以用作LPS诱导的AKI的治疗目标。并降低体内和体外组织蛋白酶L和乙酰肝素酶的表达水平。此外,ELISA和Western blot结果表明,Phil抑制LPS诱导的ARDS小鼠的NF-κB和MAPK信号通路的激活并降低炎性细胞因子(IL-1β,IL-6和TNF-α)的水平。 。通常,针对内皮糖萼HS的保护作用和Phil的炎症反应抑制作用可以用作LPS诱导的AKI的治疗目标。并降低体内和体外组织蛋白酶L和乙酰肝素酶的表达水平。此外,ELISA和Western blot结果表明,Phil抑制LPS诱导的ARDS小鼠的NF-κB和MAPK信号通路的激活并降低炎性细胞因子(IL-1β,IL-6和TNF-α)的水平。 。通常,针对内皮糖萼HS的保护作用和Phil的炎症反应抑制作用可以用作LPS诱导的AKI的治疗目标。
