P selectin sickle cell

Background: The up-regulation of P-selectin in endothelial cells and platelets contributes to the cell-cell interactions that are involved in the pathogenesis of vaso-occlusion and sickle cell-related pain crises. P-selectin is a type-1 transmembrane protein that in humans is encoded by the SELP gene. P-selectin functions as a cell adhesion molecule (CAM) on the surfaces of activated endothelial cells, which line the inner surface of blood vessels, and activated platelets. In unactivated endothelial cells, it is stored in granules called Weibel-Palade bodies. 2019-11-15 · It is the first and only targeted biologic that works by binding to P-selectin, a cell adhesion protein that plays a central role in the multicellular interactions that can lead to vaso-occlusion in sickle cell disease. Sickle cell disease (SCD) is caused by a homozygous mutation in the β-globin gene, which leads to erythrocyte sickling, vaso-occlusion, and intense hemolysis. P-selectin inhibition has been shown to prevent vaso-occlusive events in SCD patients, however, the chronic effect of P-selectin inhibition in SCD remains to be determined.

2019-11-17 · P-selectin sits on the cells lining the inside walls of blood vessels and in platelets. In sickle cell disease, P-selectin can help the crescent-shaped red blood cells stick to the blood vessel walls.

Ned Pagliarulo contributed reporting. Patients with sickle cell disease (SCD) have a unique cardiomyopathy with restrictive physiology characterized by diastolic dysfunction, left atrial dilation, and normal systolic function, according to research published in JACC: Cardiovascular Imaging.

Kato GJ, et al. Nat Rev Dis Primers. Potential Treatment for Sickle Cell Anemia: P-Selectin Inhibitor. Sickle cell disease affects millions of people throughout the world, particularly black and Circulating platelets (type of cells in the blood that has a role in blood clotting and stopping of bleeding) in SCD patients express higher levels of P-selectin, a Sickle cell disease (SCD) is a monogenic disorder that afflicts approximately 100,000 Americans and E-selectin and P-selectin results in leukocyte adhesion. Figure 1.

A total of 134 patients with SCD (median age: 11 years) were included in the 2-part study. Vaso-occlusive episodes (VOEs) in sickle cell disease (SCD) are characterized by severe pain and microvascular obstruction precipitated by adhesive interactions among endothelial cells (ECs), red blood cells, white blood cells (WBCs), and platelets. P-selectin contributes to microvascular occlusion by supporting abnormal interactions between The adhesion of sickle cells to the vascular endothelium involves various mediators, including integrin α4β1, CD36, and ICAM-4, which are responsible for the cellular interaction with the endothelium directly through E-selectin, P-selectin, integrins, and VCAM-1, or indirectly through molecules such as thrombospondin and von Willebrand factor [72, 73].

Pharmacodynamics (PD): Percentage of P-selectin inhibition and PD-AUC inhibition of crizanlizumab at 5.0 mg/kg in SCD patients, Week1 Day1 Pre-dose, 2hr,

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. 2020-02-24 · P-selectin is one of the cell adhesion proteins found in excess on the surface of activated platelets and endothelial cells in blood vessels due to the inflammatory environment in sickle cell disease – which can lead to vaso-occlusion, potentially causing sickle cell pain crises or VOCs. Flow cytometric quantification of platelet P‐selectin expression was carried out in 23 patients with sickle cell disease before and after automated red cell exchange. P‐selectin expression was quantified as a binding index for platelet P‐selectin (the percentage of positive platelets multiplied by the mean fluorescence of positive platelets).
