Abstract

Leukocytes, particularly neutrophils, have been implicated in ischemic- reperfusion organ injury (IRI). However, their role in kidney IRI is controversial: Leukocytes express the adhesion molecules CD11/CD18 on their surface, which mediate many functions that can lead to tissue damage. To determine the role of CD11a and CD11b in IRI in the kidney, uninephrectomized Sprague-Dawley rats were pretreated with monoclonal antibodies (MAbs) directed against CD11a and CD11b or control MAbs. The serum creatinine (SCr), complete blood count, and kidney histopathological damage scores (PDS) (scale: 0-4) were assessed prior to and 24 h after 60 min of ischemia. Mean SCr 24 h after ischemia was significantly decreased in the anti-CD11a- and - CD11b-treated group compared with the control MAb-treated group (2.5 ± 0.3 mg/dl vs. 3.4 ± 0.2 mg/dl, P < 0.05). PDS were also reduced in the CD11a and CD11b group compared with controls (2.7 ± 0.2 vs. 3.5 ± 0.1, P < 0.001). These data show that the CD11/CD18 leukocyte adhesion pathway plays a role in mediating ischemic acute renal failure in rats.
