ABSTRACT
AIM:
To explore the changes of L-selectin expression on peripheral blood polymorphonuclear leukocytes (PMNs) and their significance in rats with acute lung injury (ALI).METHODS:
ALI model in rat was established by intravonous injection of E. coli endotoxin (ET). The expression of L-selectin on peripheral blood PMNs was measured by immunofluorescence and flow cytometry.RESULTS:
The contribution of L-selectin fluorescence signal was on the surface of PMNs membrane. The expression of L-selectin on poeripheral blood PMN was significantly lower at 5 min after injection of ET and the lowest during 15 min to 30 min, then gradually increased, but the expression of L-selectin on PMN was lower at 60 min after injection of ET than that of control animal.CONCLUSION:
In physiological state, L-selectin were expressed on the surface of PMN membrane. The protein expression of L-selectin on PMNs reduced rapidly after injection of ET and the lowest at 15 min, then gradually increased. L-selectin may play a role in the development of ALI.
