Ischemia reperfusion injury (IRI) is a leading cause of acute kidney injury with
high morbidity and mortality due to limited therapy. Here, we examine whether
sesamin attenuates renal IRI in an animal model and explore the underlying
mechanisms. Male mice were subjected to right renal ischemia for 30 min followed
by reperfusion for 24 h with sesamin (100 mg/kg) during which the left kidney was
removed. Renal damage and function were assessed subsequently. The results showed
that sesamin reduced kidney ischemia reperfusion injury, as assessed by decreased
serum creatinine (Scr) and Blood urea nitrogen (BUN), alleviated tubular damage
and apoptosis. In addition, sesamin inhibited neutrophils infiltration and
pro-inflammatory cytokines tumor necrosis factor (TNF)-? and interleukin (IL)-1?
production in IR-preformed kidney. Notably, sesamin promoted the expression of
CD39, A2A adenosine receptor (A2AAR), and A2BAR mRNA and protein as well as
adenosine production. Furthermore, CD39 inhibitor or A2AR antagonist abolished
partly the protection of sesamin in kidney IRI. In conclusion, sesamin could
effectively protect kidney from IRI by inhibiting in?ammatory responses, which
might be associated with promoting the adenosine-CD39-A2AR signaling pathway.
