P- and E-selectin-deficient mice are susceptible to cerebral ischemia-reperfusion injury.
We examined brain sections from P- and E-selectin-deficient mice (-/-) and their nontransgenic littermates (+/+) after focal cerebral ischemia and reperfusion (I/R) tissue injury. There was no difference in the subsequent infarct volume after 3 h of ischemia and 21 h of reperfusion. These data indicate that selectin-independent mechanisms mediate tissue injury after a prolonged period of transient focal ischemia.
