IFNG and acute kidney injury: Previous studies have reported that the plasma levels of IFN-γ during the early postoperative stage were either declined or not significantly changed in the kidney transplantation-associated AKI (Karczewski et al., 2009; Snoeijs et al., 2011; De Serres et al., 2012; Xu et al., 2013) and even the pediatric CSA-AKI (Greenberg et al., 2018), which suggests that plasma IFN-γ might be a novel potential biomarker selective for the CSA-AKI in adults.
