Blockade of K(ATP) channels reduces endothelial hyperpolarization and leukocyte recruitment upon reperfusion after hypoxia.

Ischemia/reperfusion injury in renal transplantation leads to slow or initial nonfunction, and predisposes to acute and chronic rejection. In fact, severe ischemia reperfusion injury can significantly reduce graft survival, even with modern immunosuppressive agents. One of the mechanisms by which ischemia/reperfusion causes injury is activation of endothelial cells resulting in inflammation.

Ischemia/reperfusion induces the recruitment of leukocytes from whole blood under flow conditions.

Ischemia/reperfusion (I/R) occurs in a number of pathological conditions, including myocardial infarction, stroke, and organ transplantation. During the reperfusion phase, leukocytes are recruited into affected tissues, where they can cause tissue damage and organ failure. Various in vitro models have been developed to study the role of adhesion molecules in I/R-mediated leukocyte recruitment.
