ABSTRACT
Ischemia reperfusion damage usually occurs after renal transplantation. These injuries can stimulate the innate immune system, trigger an inflammatory response and ultimately activate the adaptive immune system. These events may result in rejection, graft fibrosis and chronicallograft nephropathy. Different mechanisms contribute to innate immune system activation following ischemia reperfusion injury in renal transplants. Some of these mechanisms are known and described by investigators while the remaining are still unknown. To clarify the precise mechanisms underlying the innate immune system activation and rejection progression helps us to plan therapeutic protocols to reduce immunologic responses to ischemic events and to improve the graft function and outcome. In this review, we will discuss how innate and adaptive immune systems are activated during an ischemic insult and thereafter discuss related therapeutic interventions to block the activating pathways
