Selectin ligands.
The selectins initiate many critical interactions among blood cells. The volume of information and diversity of opinions on the nature of the biologically relevant ligands for selectins is remarkable. This review analyzes the matter and suggests the hypothesis that at least some of the specificity may involve recognition of "clustered saccharide patches."
متن کاملSelectin glycoprotein ligands.
Lectin selectins and their counter-receptors participate in discontinuous cell-cell interactions concurrent with leukocyte tethering and rolling on endothelium, which, in consequence, leads to leukocyte penetration to lymphatic organs and generation of inflammation sites. Counter-receptors are glycoproteins in which carbohydrate units, the direct selectin ligands, are built into the polypeptide...
متن کاملHigher-affinity oligosaccharide ligands for E-selectin.
A series of synthetic oligosaccharides based on sialyl Lewis x (sLex; Neu5Ac alpha 2-3Gal beta 1-4[Fuc alpha 1-3]GlcNAc) and sialyl Lewis a (sLea; Neu5Ac alpha 2-3Gal beta 1-3[Fuc alpha 1-4]GlcNAc) was used to study the binding interactions of selectins. E-selectin-immunoglobulin fusion protein (E-selectin-Ig) bound to immobilized bovine serum albumin (BSA)-neoglycoproteins containing sLex or s...
متن کاملThe HNK-1 reactive sulfoglucuronyl glycolipids are ligands for L-selectin and P-selectin but not E-selectin.
E-selectin, L-selectin, and P-selectin are related cell adhesion molecules that bind via their lectin domains to sialyl Lewis x and related carbohydrate determinants. Reports have indicated that sulfated glycolipids and polysaccharides also bind selectins. To extend these findings, we compared binding of selectin-IgG chimeras to immobilized sulfated and sialylated glycosphingolipids. E-, L-, an...
متن کاملO-glycans direct selectin ligands to lipid rafts on leukocytes.
Palmitoylated cysteines typically target transmembrane proteins to domains enriched in cholesterol and sphingolipids (lipid rafts). P-selectin glycoprotein ligand-1 (PSGL-1), CD43, and CD44 are O-glycosylated proteins on leukocytes that associate with lipid rafts. During inflammation, they transduce signals by engaging selectins as leukocytes roll in venules, and they move to the raft-enriched ...
