Electronic Thesis and Dissertation Repository
Ischemia/reperfusion injury (IRI) is inherent to renal transplantation (RTx) and is initiated when blood supply is necessarily removed during organ procurement (ischemia) and subsequently restored upon engraftment (reperfusion). During renal ischemia, ATP depletion causes tubular epithelial cell (TEC) injury and subsequent release of pro-inflammatory mediators. Upon reperfusion, influx of O2 causes reactive oxygen species (ROS) production and infiltration of innate immune cells which release damaging ROS and proteases. Prolonged periods of IRI are associated with increased risk of delayed graft function (DGF) and decreased long-term graft survival. The endogenously produced gasotransmitter, hydrogen sulfide (H2S), has recently been …
