Selectin 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 کاملSelectin 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 کاملMonospecific and common glycoprotein ligands for E- and P-selectin on myeloid cells
E- and P-selectin are inducible cell adhesion molecules on endothelial cells, which function as Ca(2+)-dependent lectins and mediate the binding of neutrophils and monocytes. We have recently identified a 150-kD glycoprotein ligand for E-selectin on mouse myeloid cells, using a recombinant antibody-like form of mouse E-selectin. Here, we report that this ligand does not bind to an analogous P-s...
متن کاملIdentification of leukocyte E-selectin ligands, P-selectin glycoprotein ligand-1 and E-selectin ligand-1, on human metastatic prostate tumor cells.
Prostate tumor cells, which characteristically metastasize to bone, initiate binding interactions with bone marrow endothelium under blood flow conditions through binding interactions with E-selectin. We hypothesized that E-selectin ligands on prostate tumor cells are directly associated with bone-metastatic potential. In this report, we elucidate the identity of E-selectin ligands on human met...
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...
