近日,利物浦大学和AKL研发有限公司(AKLRD)进行的一项新研究发表在《炎症药理学》(Inflammopharmacology)上,强调了一种新的药物APPA对人体炎症免疫反应的潜在益处,通过靶向中性粒细胞,能够有选择地控制人体的免疫反应。

  在许多炎症情况下,例如骨关节炎、类风湿性关节炎和最近的COVID-19,当免疫系统过度和不可控制地被激活后,会出现主要的并发症和广泛的组织损伤。寻找新的方法来选择性地控制这种过度活动可能会有重大的临床益处。
 中性粒细胞
  为了健康,我们需要一种有效的免疫反应,否则我们将屈服于压倒性的感染,即使是日常细菌感染也是如此。然而,有时候即使没有感染,我们的免疫系统也会变得过度活跃,并通过炎症来引起损伤。有时候这可能是极端的。事实上,许多类风湿性疾病,例如类风湿关节炎和骨关节炎都是由炎症引起的,一直以来,人们一直在寻找方法,能够有选择地阻断免疫系统过度活跃的有害影响,而不阻断我们抵御感染的能力。
  中性粒细胞是我们血液中最丰富的免疫细胞,它们被迅速送往感染部位,在那里它们通过破坏感染有机体和产生被称为细胞因子的信号蛋白,完成了拯救生命的抗菌功能。细胞因子有助于协调其他免疫系统细胞的募集和活动来对抗感染。利物浦大学的研究中有很多证据表明,这些细胞是导致风湿性疾病的重要因素。
  细胞因子风暴和COVID-19
  在某些情况下,如果细胞因子水平过高,它们就会促发一种极端炎症反应,也称细胞因子风暴。这种细胞因子风暴会引发大量的炎症,会使血管堵塞或破裂。这会影响整个循环系统,细胞因子风暴会造成巨大的损伤,多器官功能衰竭、败血症甚至死亡,并且似乎在严重的COVID-19疾病中起主要作用。
  几十年来,科学家们和临床医生们已经了解到抑制中性粒细胞的潜在益处,但在不削弱免疫系统对感染的反应情况下,这样做的任何尝试都失败了。
  APPA
  APPA是AKL公司开发出来的一种新型的药物,用于治疗骨关节炎,骨关节炎是一种由低度炎症引起的世界性的致残问题。由利物浦由风湿病专家罗伯特·穆茨(Robert Moots)教授领导的正式临床评估的第一部分最近已经成功完成。现在,在利物浦大学和AKL公司的合作下,该药物对中性粒细胞的影响已经得到了检测和公布。
  这项研究明确证实了APPA抗炎的潜力,但并没有削弱宿主对感染的防御能力。
 利物浦大学的风湿病学教授、安特里大学医院的研发主任罗伯特·穆茨表示,“我们已经证明,APPA有可能抑制导致风湿性疾病的严重炎症,但不会影响中性粒细胞的关键抗菌作用。我们等了好多年才等到这种选择性药物。我们的研究结论表明,在帮助安全地调节侵略性免疫反应方面,不仅在每天治疗的关节炎中,甚至在COVID-19中,APPA都发挥着重要作用。”
  利物浦大学研究该项目的中性粒细胞科学家史蒂夫·爱德华兹(Steve Edwards)表示,“在不影响中性粒细胞抵抗感染的情况下,通过治疗手段使中性粒细胞对炎症产生有害影响,一直是世界各地许多科学家的长期目标,最终,我们或许能够实现这一目标。”

 AKL公司的首席执行官大卫·迈尔斯(David Miles)表示,这些令人兴奋的结果支持了在骨关节炎患者中观察到的有利的临床结果,这也表明APPA在治疗涉及炎症的广泛疾病方面发挥着重要作用。”
