We examined brain sections from P- and E-selectin-deficient mice (-/-)and t
heir nontransgenic littermates (+/+) after focal cerebral ischemia and repe
rfusion (I/R) tissue injury. There was no difference in the subsequent infa
rct volume after 3 h of ischemia and 21 h of reperfusion. These data indica
te that selectin-independent mechanisms mediate tissue injury after a prolo
nged period of transient focal ischemia. (C) 1999 Elsevier Science B.V. All
