Abstract

Background

Ischemia/reperfusion injury (IRI) is a leading cause of acute kidney injury (AKI) that induces inflammation and oxidative stress. The main goal of the current study was to assess the impact of fingolimod on kidney IRI in rats.

Methods

For this purpose, 18 male Wistar rats (220–250g) were divided into three groups including (i) Sham, (ii) I/R, and (iii) fingolimod+I/R. The last group was pretreated with a single dose of fingolimod (1mg/kg) (intraperitoneal injection) before induction of the I/R injury. Kidney function, oxidative stress marker (malondialdehyde), and antioxidant markers (catalase, superoxide dismutase, glutathione, glutathione peroxidase, and total antioxidant capacity) were determined in the kidney tissue of the rats. Moreover, kidney samples were taken for histological analysis.

Results

Fingolimod pre-treatment could significantly improve the glutathione peroxidase (p<0.01) and glutathione (p<0.001) activities along with the total antioxidant capacity levels (p<0.001) when compared to the I/R group. Moreover, significant recovery of kidney function and histology was seen in the fingolimod+ I/R group compared to the I/R group (p<0.01).

Conclusion

Fingolimod pretreatment could improve renal function, antioxidant capacity, and histological alterations after I/R injury. Hence, it might protect the kidney against IRI-related kidney damage including AKI and transplantation.
