**8. Markers of renal ischemia/reperfusion injury**

**Leukocyte elastase** (LE, neutrophil elastase), is a 30-kDa glycoprotein serine protease released from neutrophils as a mediator of ischemia/reperfusion injury after renal transplantation. Urinary LE is a simple noninvasive marker of the neutrophil activation after renal transplantat (Zynek-Litwin et al., 2010).
