ReviewThe role of adhesion molecules and T cells in ischemic renal injury.
The pathophysiology of ischemic acute renal failure is complex, incompletely understood and there are no specific therapies. Descriptive observations in human acute renal failure, as well as mechanistic studies in animals, have demonstrated an important pathophysiological role for leukocytes and leukocyte adhesion molecules. The purpose of this review is to summarize and interpret the recent advances on the role of T cells and leukocyte adhesion molecules in ischemic acute renal failure. ⋯ The identification of T cells and new adhesion molecule pathways as modulators of ischemic acute renal failure offers novel and feasible therapeutic opportunities for both native and transplant acute renal failure. Rigorous clinical trials are required to translate these basic findings to the bedside. In addition, mechanistic studies are needed to elucidate the molecular mechanisms by which these pathways modulate kidney injury. The identification of T cell engagement in ischemic renal injury can also help explain long-standing observations linking alloantigen-independent and alloantigen-dependent renal damage.
