Plasma Selectin (P-selectin), also known CD62P and GMP-140, is a cell adhesion molecule and a member of the Selectin family. It is found in granules in endothelial cells and activated platelets. In unactivated endothelial cells, it is stored in granules Weibel …

Combined, E‐selectin and P‐selectin mAb treatment inhibited T cell accumulation in all four types of reactions, and significantly more than E‐selectin blockade alone in migration to Con A. Results in E‐selectin‐ and P‐selectin‐deficient mice confirmed these observations, and demonstrated strain‐dependent differences in the contributions of the two selectins. 2018-08-02 · Moreover, whereas E-selectin is derived solely from endothelial cells, the other CAMs are derived from multiple sources such as platelets (P-selectin), leukocytes (ICAM-1) and cell types of non-vascular origin (VCAM-1), which may explain the strong association of E-selectin with aortic PWV . P-selectin–deficient (Selp −/−) mice bred with apolipoprotein E–deficient (Apoe −/−) mice or with low-density lipoprotein (LDL) receptor–deficient (Ldlr −/−) mice develop smaller atherosclerotic lesions than control mice. 15 – 18 Bone marrow transplantation experiments suggest that P-selectin on nonhematopoietic presumably endothelial cells contributes more to atherosclerosis than P-selectin on hematopoietic cells. 19 However, infusion of activated platelets initiates The identity of the amplified baboon cDNA fragments was confirmed by DNA sequencing; the nucleotide sequence of the baboon P-selectin cDNA fragment was 99% identical to that of the human P-selectin cDNA, and the nucleotide sequence of the baboon E-selectin cDNA was 97% identical to that of the human E-selectin cDNA.

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). Both E-and P-selectins are expressed on human arterial luminal endothelial cells of atherosclerotic plaques (195, 196), and mouse studies have shown that E-selectin and/or P-selectin deficiency substantially reduces the formation of atherosclerotic plaques, suggesting an overlapping function of these two selectins in the development of atherosclerotic lesions (197, 198). Raised levels of E-selectin (mean [± SD], 178.9 ± 30.5 vs 59.4 ± 4.7 ng/mL, respectively; p < 0.001) and P-selectin (mean, 232.6 ± 29.9 vs 67.6 ± 14.2 ng/mL, respectively; p < 0.001) were detected in HP patient sera compared to control subjects, while L-selectin levels showed no differences between groups. P-Selectin and Vaso-Occlusion. There are 3 members of the selectin family of cytoadhesion molecules: E-selectin, P-selectin, and L-selectin. P-selectin is found in storage granules of resting endothelial cells (Weibel-Palade bodies) and platelets (alpha granules) and is expressed on cell membranes upon activation.8 P-selectin expression in platelets is a marker of platelet activation. Histograms are depicted in (A‐D, the striped line represents antibody control) and percentage of P‐selectin positive platelets in (E).

13 Oct 2017 E-selectin is primarily expressed on endothelial cells [2], and mediates slow, steady rolling adhesion [3], whereas L-selectin is constitutively

The three selectins, E-selectin (CD62E), L-selectin (CD62L) and P-selectin (CD62P), are related both structurally and functionally. They have been extensively studied due to their role in the inflammatory response and their potential use as therapeutic targets. E-selectin, also known as CD62 antigen-like family member E, endothelial-leukocyte adhesion molecule 1, or leukocyte-endothelial cell adhesion molecule 2, is a selectin cell adhesion molecule expressed only on endothelial cells activated by cytokines.

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. E-selectin gained a new role since it was demonstrated to be involved in cancer cell trafficking, stem-like …

Unstable angina with fatal outcome: dynamic Subcutaneous vs intravenous heparin in the treatment of deep venous Plasma P-selectin is increased in thrombotic consumptive platelet disorders.

New!!: P-selectin and Crizanlizumab · See more » Deep vein thrombosis. Deep vein thrombosis (DVT), is the formation of a blood clot in a deep vein, most commonly E-selectin recognises and binds to sialylated carbohydrates present on the surface proteins of certain leukocytes. These carbohydrates include members of the Lewis X and Lewis A families found on monocytes, granulocytes, and T-lymphocytes. Function .

35.8, MWU = 584.500, P = 0.001), respectively. All binary logistic regression models were statistically significant. The effects of branching on the ligand activities have been investigated using mice deficient in core 2 GlcNAcT I. 77,101,102 The general conclusion is that the P-selectin ligand is dependent on branching, but the E-selectin ligand is not or only partially so. 101,102 As an example, rolling of neutrophils and activated T cells from core 2 GlcNAcT I-deficient mice is severely inhibited on cells transfected with P-selectin cDNA, but is normal on cells transfected with E-selectin cDNA.

It takes about two hours, after cytokine recognition, for E-selectin to be expressed on the endothelial cell's surface.
