炎症是 AKI 小鼠模型的共同特征。人们对限制炎症和减轻 AKI 严重程度的内源性机制知之甚少。 Zhou等人将颗粒体蛋白前体确定为一种这样的保护性介质。在 AKI 的缺血性和肾毒性模型中,颗粒体蛋白前体的缺乏与炎症增加和损伤增加相关。此外,即使在 AKI 发生后施用外源颗粒体蛋白前体,也能减少 AKI。建议干扰 NOD2 通路作为一种可能的保护机制。基于 PRGN 的疗法正在开发中,可能应用于 AKI 的治疗或预防。
Inflammation is a common feature of murine models of AKI. The endogenous mechanisms which serve to limit inflammation and reduce the severity of AKI are poorly understood. Zhou et al identify progranulin as one such protective mediator. Deficiency of progranulin was associated with increased inflammation and increased injury in both ischemic and nephrotoxic models of AKI. Moreover, administration of exogenous progranulin reduced AKI even when delivered after AKI was established. Interference in NOD2 pathways is suggested as a possible mechanism for protection. PRGN-based therapeutics are under development and might have application in the treatment or prevention of AKI.
