This together with minor differences in fucose binding, accounts for the 10-fold higher affinity of E-selectin for SLe x as compared to P-selectin. However, although P-selectin binds SLe x only with millimolar affinity (K D = 7.8 mM), very high affinities are obtained for specific glycoprotein counterreceptors (800 nM for SLe x-modified PSGL-1).

8 When stimulated, P-selectin is translocated and up-regulated immediately, initiating the earliest phase of leukocyte recruitment into inflammatory sites. 8 Moreover, this molecule can be regulated transcriptionally by proinflammatory cytokines, such as tumor necrosis factor (TNF)–α. 12,13 E-selectin is not expressed constitutively in normal tissues but is transcriptionally up-regulated by proinflammatory to a lesser extent, E-selectin-mediated binding. Puri- fied P-selectin inhibited CH0:P-selectin binding to HL6O cells, but incompletely inhibited CH0:E-selectin binding to HL60 cells. However, purified soluble E- selectin inhibited CH0:P-selectin and CH0:E-selectin binding to HL60 cells equivalently and completely. This together with minor differences in fucose binding, accounts for the 10-fold higher affinity of E-selectin for SLe x as compared to P-selectin.

P-selectin are therefore functional under divergent conditions. Similarly to cell-surface P-selectin, E-selectin is rapidly down- regulated by internalization and degradation in lysosomes; however, the intracellular targeting mechanism of E-selectin is still unknown (63,72).

In addition to ICAM-1, the selectin family of adhesion molecules influences PMN– endothelial cell interaction. The selectins designated L-, P-, and E-selectin are a  

E-selectin is a vascular adhesion molecule expressed mainly on endothelium, and its primary role is to facilitate leukocyte cell trafficking by recognizing ligand surface proteins.
