摘要: 目的 探究 GSK484 对强直性脊柱炎 (ankylosing spondylitis, AS) 中性粒细胞胞外诱捕网 ( neutrophil extracellular traps, NETs) 形成和炎症反应的作用及其相关机制方法 检测 AS 患者和健康受试者外周血 PAD4、 H3cit、 IL-1β、 IL-6 水平和 NETs 形成差异30 Balb / c 小鼠分为: 对照组模型组、GSK484 给药组模型组、 GSK484 给药组进行 AS 造模, GSK484 给药组造模后连续一周灌胃 4 mg / kg GSK484, 其余组灌胃同体积生理盐水结束后比较各组小鼠踝关节损伤评分, NETs 水平和 PAD4、 H3cit、IL-6、 IFN-γ 水平结果 与健康受试者比较, AS 患者外周血 PAD4、 H3cit、 IL-1β、 IL-6 水平升高, NETs 形成和 IL-1β、 IL-6 水平升高与模型组比较, GSK484 给药组小鼠踝关节损伤评分、 NETs 形成和 PAD4、 H3cit、IL-1β、 IL-6 水平降低结论 GSK484 可抑制 NETs 形成, 为缓解 AS 炎症反应提供了新的治疗策略

Abstract: Objective To investigate the effect of GSK484 on neutrophil extracellular traps(NETs) formation and inflammatory response in ankylosing spondylitis (AS) and its related mechanisms. Methods The levels of PAD4, H3cit, IL-1β, IL-6, and the formation of NETs were assessedin peripheral blood from AS patients and healthy subjects. Thirty Balb/ c mice were divided into 3 groups: control, model, and GSK484 treatment groups. The model and GSK484 treatment groups were subjected to an AS model induction, followed by oral administration of 4 mg / kg GSK484 for a week in the treatment group, while the other groups received an equivalent volume of saline. Ankle joint damage scores, NETs levels, and the levels of PAD4, H3cit, IL-6, and IFN-γ were compared among the groups aftertreatment. Results Compared to healthy subjects, AS patients showed elevated levels of PAD4, H3cit,IL-1β, IL-6, and increased formation of NETs. The GSK484 treatment group exhibited reduced ankle joint damage scores, NETs formation, and levels of PAD4, H3cit, IL-1β, IL-6 compared to the modelgroup. Conclusion GSK484 inhibits the formation of NETs, offering a new therapeutic strategy for alleviating the inflammatory response in AS.
