Acute kidney injury comprises a heterogeneous group of conditions characterized by a sudden decrease in renal function over hours to days. Contrast-induced acute kidney injury (CI-AKI) is caused by radiographic contrast agents used in diagnostic imaging. In the current issue of the JCI, Lau et al. use a mouse model of CI-AKI to study the role of resident and infiltrating phagocytes, recruited leukocytes, and tubular cells in the immune surveillance response to contrast agents. This study has the potential to provide innovative therapies for human CI-AKI.
急性肾损伤包括一组异质性疾病,其特征是肾功能在数小时至数天内突然下降。对比剂诱导的急性肾损伤(CI-AKI)是由诊断成像中使用的造影剂引起的。在本期 JCI 中,Lau 等人使用 CI-AKI 的小鼠模型研究了固有和浸润性吞噬细胞、募集的白细胞和肾小管细胞在对比剂免疫监视反应中的作用。这项研究有可能为人类 CI-AKI 提供创新的治疗方法。
