Recently, the selectin family of glycoprotein adhesion molecules (P-selectin, E-selectin, and L-selectin) has been implicated in the pathogenesis of a number of inflammatory disease states. The selectins modulate the early adhesive interactions between circulating neutrophils and the endothelium. Both P-selectin and E-selectin can be expressed on the surface of endothelial cells following

In this review, we will highlight the various approaches taken toward the development of sLe x mimetics as antagonists of E‐ and P‐selectin, including the use of structural information about the selectins and their interactions with sLe x that have been revealed through the use of NMR, protein crystallography and molecular modeling. © 2002 Wiley Periodicals, Inc.

Jianhui Wu In vitro, IQCA-TASS acted on P-selectin and down-regulated P-selectin expression. The IC50 values of . 2 Feb 2017 In conclusion, the P-selectin inhibitor crizanlizumab was associated with a significantly lower frequency of sickle cell–related pain crises than placebo among patients with sickle cell disease, and crizanlizumab appeared t P-Selectin Inhibitors. Selectins, also designated CD62 antigens, comprise a family of carbohydrate-binding proteins involved in mediating cellular interactions with leukocytes.

15 Nov 2006 We further investigated the use of a novel complement inhibitory protein in a therapeutic paradigm. Complement receptor 2 (CR2)-Crry inhibits complement activation at the C3 stage and targets to sites of complement activat It is now considered more likely that an inhibition in the recruitment of leukocyte- derived microparticles was the primary factor responsible for the decreased fibrin formation. The next evidence indicating a role of P-selectin in hemosta 19 Aug 2014 To confirm this hypothesis, a P‑selectin inhibitor was admin- istered to an atherosclerosis formation model, plaque rapture model and neointimal hyperplasia model.

Selective inhibitors of P- selectin- mediated leukocyte endothelial-cell interactions may ther They also showed that inhibition of P-selectin and ICAM-1 with a monoclonal antibody significantly attenuated retinal ischemia-reperfusion injury. A P-selectin monoclonal antibody reduced leukocyte rolling along the major retinal veins an 2 Feb 2017 Patients with sickle cell disease may experience pain crises related to P-selectin, which contributes to vaso-occlusion.

The best characterized ligand for P-selectin is called P-selectin glycoprotein ligand-1 (PSGL-1) which is expressed on the surface membranes of all leukocytes.

In recent years, the development of potent P-selectin inhibitors has been the subject of extensive investigation and included mostly synthetic analogs of PSGL-1 and its sLe x moiety (reviewed by Lefer35), including sulfopeptides, which are based on the N-terminal domain of PSGL-1.29,36 However, it has been difficult to design P-selectin–specific antagonists from these parent compounds, because PSGL-1 and sLe x also display affinity for E-selectin and L-selectin.26,37,38 The peptides we

However, HM is P-selectin/ PSGL-1 inhibition is a treatment whose target does not involve the inhibition of the coagulation cascade, but the inhibition of inflammation. Different compounds have already been tested in our laboratory, with efficacy similar to enoxaparin. P-selectin inhibition is a promising therapeutic approach because it: 1.

A proof-of-principle study established that doses of heparin lower than what are used for anticoagulation but sufficient to block P-selectin improved microvascular

The P-selectin specificity of the STMC was defined by the anomeric linkage of the C-C bond. This STMC hexasaccharide is an effective inhibitor of P-selectin in vivo. We show that selective inhibition of heparanase attenuates metastasis in B16-BL6 melanoma cells, expressing high levels of this endoglycosidase, but has no effect on the metastasis of MC-38 carcinoma cells that express little or no heparanase activity. Selectin P ligand, also known as SELPLG or CD162 (cluster of differentiation 162), is a human gene.

As such, it plays a critical role in the tethering of these cells to activated platelets or endothelia expressing P-selectin. compartments: P-selectin to secretory granules, E-selectin to the plasma membrane, and L-selectin to the tips of microfolds on leukocytes. Selectin ligands There are many candidate ligands for selectins, but only P-selectin glycoprotein ligand 1 (PSGL-1) has been extensively characterized at the molecular, cellular and functional level (Fig.

SCD mice were injected with the anti-P-selectin aptamer, and cell adhesion was observed under hypoxia. The anti-P-selectin aptamer inhibited the adhesion of sickle RBCs and leukocytes to endothelial cells by 90% and 80%, respectively. The anti-P-selectin aptamer also increased microvascular flow velocities and reduced the leukocyte rolling flux. P-selectin is a type-1 transmembrane protein that in humans is encoded by the SELP gene.
