Abstract

The expression and localization of P- and E-selectins in rat brain (n= 126) were examined using immunohistochemical techniques at various time points after induction of middle cerebral artery (MCA) occlusion in the suture, thrombotic and embolic models of stroke. Expression of P-or E-selectin was not observed in brain tissue of sham operated control rats (n = 9). P-selectin immunoreactivity was detected as early as15 min and decreased to control level at 1 h after the onset of the MCA occlusion in all three models. P-selectin then slightly increased at 2 h and peaked at 6 h after MCA occlusion. E-selectin immunoreactivity was first observed at 2 h and peaked at 6 h and 12 h of after MCA occlusion in all three models. P- and E-selectin immunoreactivity was colocalized with von Willebrand factor immunoreactive microvessels. 90.4 +/- 2.0% of all vessels expressing P-selectin immunoreactivity were 7.5 to 30.0 mu m in diameter; 3.6 +/- 1.4% were contained in vessels smaller than 7.5 mu m, and 6.0 +/- 1.8% were localized in vessels greater than 30.0 mu m in diameter. The percent distribution of E-selectin immunoreactive vessels were 75.9 +/- 2.1% in vessels 7.5 to 30.0 mu m in diameter; 23.6 +/- 2.2% were in vessels smaller than 7.5 mu m, and 0.6 +/- 0.4% were localized in vessels greater than 30.0 mu m in diameter. These findings indicate that the temporal profiles of P-and E-selectin expression are independent of these models of MCA occlusion and are consistent with the time course of selectin mediated leukocyte infiltration after focal cerebral ischemia in the rat.
