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.
