Ischemia-reperfusion and immediate T cell responses

The pathogenesis of ischemia-reperfusion injury (IRI) is complex and not well understood. Inflammation plays an important role in IRI, with involvement of leukocytes, adhesion molecules, chemokines and cytokines. Emerging data suggest a role of T cells as mediators of IRI both in renal and extra-renal organs. Divergent roles of T cell subsets have also been elucidated, suggesting a more complicated role of T cells in the different phases of IRI This review presents recent evidence from various animal models that advances our understanding of the role T cells play in IRI These findings entertain the possibility of using immunotherapeutic agents for the prevention and treatment of IRI (C) 2007 Elsevier Inc.
