Abstract
Germ cell specific apoptosis after ischemia-reperfusion (I/R) induced testicular injury is dependent on neutrophil recruitment to the testis. Intravascular adhesion molecules like the P- and E-selectins play an important role in this recruitment. The purpose of this study was to inhibit neutrophil recruitment in I/R induced testicular injury by using a function-blocking monoclonal anti-mouse P-selectin antibody, Adult mice were subjected to a 2 h period of testicular torsion (ischemia) followed by detorsion (reperfusion). Ten minutes after the onset of reperfusion, mice received either 100 mu g of a function-blocking monoclonal P-selectin antibody (FBMAB group) or isotype-matched control antibody (IMCA group). Separate groups of mice underwent sham-operation (SO group) or received 500 ng of TNF alpha (IF group) to induce inflammation, Mice were sacrificed 24 h after reperfusion and testiscular interstitial cells were isolated and analyzed for the presence of neutrophils by means of flow cytometry.
