Compared with IR-induced AKI alone, ADMSC treatment significantly decreased the number of apoptotic cells, the level of total urinary protein and serum creatinine, the expression of pro-inflammatory cytokines (IL-6, TNF-α, IL-1β, IFN-γ, TNF-α, IFN-γ, and TGF-β), and the inflammation-associated proteins (HGF and SDF1), but increased the expression of the anti-inflammatory cytokine, IL-10, and the anti-apoptotic regulator, Bcl-2.
The progression of OPG levels paralleled the deterioration of kidney and endothelial functions from sepsis to sepsis-AKI, revealed as progressively increased levels of serum E-selectin (15.3%), endothelin-1 (ET-1) (19.6%), and decreased nitric oxide (NO) (29.7%), associated with elevations of TNF-α (25.5%) and TGF-β (18%).
Reperfusion after ischemia may cause injury through generation of reactive oxygen and nitrogen species, inflammatory responses by increased levels of tumor necrosis factor-α (TNF-α) and interleukins (IL), and apoptotic processes, and leads to acute kidney injury (AKI).
The expression of tumor necrosis factor receptor (TNFR) 2 was increased in both kidney cell lines and experimented rat kidney tissues following acute kidney injury.
