Definitions

  • the invention relates to a method of prevention and/or treatment of ischemia-reperfusion injury.
  • the invention indicates the importance of the urokinase receptor (u- PAR) in the pathogenesis following ischemia. Consequently, the use of selective inhibitors of u-PAR are beneficial for the prevention and/or treatment of patients suffering from reperfusion injury in the heart, in organ transplantation and in the brain.
  • u- PAR urokinase receptor
  • Peri-operative myocardial ischemia causes serious morbidity and mortality for over 5 million patients each year. Once Ml occurs, the prognosis of the patient is dramatically altered: post-operative recovery times are lengthened, while non-cardiac complications are increased. Notably, 20 to 30% of those patients who experience new onset Ml, will suffer fatal myocardial infarctions or dysrhythmias within 6 years. Patients who have required CPR, have a poor prognosis. Only 4-33% of the approximately 750.000 resuscitated Americans per year survive to hospital discharge. A large proportion of deaths are associated with the "post-resuscitation" syndrome, characterized by multi- organ damage.
  • Regional Ml and global ischemia share features of hypoxia-induced endothelial cell (EC) damage and ensuing reperfusion injury:
  • EC hypoxia-induced endothelial cell
  • Global ischemia after cardiac arrest results in diffuse EC damage, with increased plasma levels of soluble thrombomodulin and adhesion molecules, as well as enhanced expression of P-selectin and ICAM-1 in the brain.
  • the latter is particularly relevant, since clinical outcome after global ischemia is inversely correlated with the extent of neurologic damage that is in part due to reperfusion.
  • transient ischemia induces long-lasting changes in excitatory synaptic transmission in CA1 hippocampal neurons.
  • Anoxic longterm synaptic potentiation is considered by some, an early marker of delayed neuronal death induced by transient ischema.
  • tissue repair is initiated with an inflammatory response characterized by influx of leukocytes.
  • Murine models of Ml both transient and permanent, have recently been well characterized and provide reliable means to study myocardial wound healing and ventricular remodelling that closely reflect these processes in man.
  • Transient ischemia induces myocyte damage and microvascular endothelial cell (EC) activation.
  • EC microvascular endothelial cell
  • tissue repair is initiated by an inflammatory response characterized by influx of leukocytes and platelets.
  • Leukocyte/platelet/EC interactions are tightly regulated by adhesion molecules.
  • Members of the selectin family and their ligands mediate tethering and rolling events of leukocytes and platelets on the EC surface.
  • ICAM-1 and VCAM-1 immunoglobulin superfamily
  • ICAM-1 and VCAM-1 immunoglobulin superfamily
  • ICAM-1 and VCAM-1 immunoglobulin superfamily
  • integrins engage members of the immunoglobulin superfamily, ICAM-1 and VCAM-1 , on EC.
  • Inflammatory cells such as monocytes and polymorphonuclear cells (PMNs) are, partly through platelets, recruited to clear damaged tissue. This is followed by mesenchymal cell division, migration, matrix synthesis and eventual ventricular remodelling.
  • PMNs polymorphonuclear cells
  • u-PAR urokinase receptor
  • u-PAR has been recognized to also play a pivotal role in integrin activation and cell signalling in leukocyte-EC interactions in vitro. And indeed, in vivo it has been shown that disruption of the u-PAR gene markedly reduces integrin-mediated recruitment of PMNs to inflamed peritoneum ((May AE, Kanse SM, Lund LR, Gisler RH, Imhof BA, Preissner KT. Urokinase receptor (CD87) regulates leukocyte recruitment via beta 2 integrins in vivo J Exp Med. 1998 Sep 21 ; 188(6):1029-37).
  • Ischemia-reperfusion injury in the heart is a complex biological process with many factors involved but the present invention surprisingly shows that mice lacking a functional u-PAR gene (u-PAR "A mice) exhibit a significantly smaller infarction after 30 minutes ischemia and 3 or 24 hours reperfusion compared to wild type mice.
  • u-PAR "A mice mice lacking a functional u-PAR gene
