Recruitment of neutrophils to sites of inflammation is mediated in part by endothelial
leukocyte adhesion molecule-1 (ELAM-1), which is expressed on activated endothelial cells
of the blood vessel walls. ELAM-1 is a member of the LEC-CAM or selectin family of
adhesion molecules that contain a lectin motif thought to recognize carbohydrate ligands. In
this report, cell adhesion by ELAM-1 is shown to be mediated by a carbohydrate ligand,
sialyl-Lewis X (SLex; NeuAcα2, 3Galβ 1, 4 (Fucα1, 3)-GlcNAc-), a terminal structure found …
