Sickle cell disease s a devastating, inherited blood disorder that affects over 90,000 persons, primarily African-Americans, in the U.S and vasoocclusive crisis is the leading cause of morbidity, mortality and health care cost in these microcirculatory abnormalities in sickle cell disease and that blocking P-selectin may be useful for preventing painful vasoocclusion in sickle cell disease. From bloodjournal.hematologylibrary P-selectin is transcriptionally downregulated after cardiopulmonary bypass at times when E-selectin and ICAM-1 are induced. Furthermore, we find that E-selectin and ICAM-1 are expressed at times and at sites where P-selectin is absent. Although it is possible that P-selectin may have been induced and lost 2020-03-02 · Indeed, in sickle mice, NADPH oxidase underlies cerebral vessel P-selectin exposure and occlusion . Notably, the sickle milieu includes numerous NADPH oxidase activators, one of which is exposure of leukocytes and endothelial cells to sickle RBCs (67, 68).

In patients with sickle cell disease (SCD), adherent masses of sickled red cells and leukocytes contribute to occlusive pain crises. P-selection was first identified in 1989. In 2019, after 3 decades of basic, translational, and clinical work with this pathway, the US Food and Drug Administration approved a P-selectin antibody, crizanlizumab to reduce frequency of pain crisis in patients more than 16 years with sickle cell disease. P-Selectin is found in the plasma of normal individuals at ng/mL concentrations.

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). 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. Abnormal blood flow accounts for most of the clinical morbidity of sickle cell disease (SCD) [1, 2]. Most notably, occlusion of flow in the microvasculature causes the acute pain crises [] that are the commonest cause for patients with SCD to seek medical attention [] and major determinants of their quality of life []. Based on evidence that endothelial P‐selectin is central to the abnormal In this study, the cerebral microcirculation was examined in wild-type (WT) and sickle cell transgenic (β S) mice to 1) determine whether SCD is associated with platelet and/or leukocyte adhesion in cerebral postcapillary venules under both unstimulated conditions and following hypoxia-reoxygenation (H/R), 2) define the contribution of P-selectin to the adhesion of platelets and leukocytes in CONCLUSIONS: Sickle cell disease promotes an increased P-selectin expression in several vascular beds.

Notably, the sickle milieu includes numerous NADPH oxidase activators, one of which is exposure of leukocytes and endothelial cells to sickle RBCs (67, 68). We measured markers of platelet activation (soluble P-selectin [sP-selectin]), fibrinolysis (D-dimer) and angiogenesis (vascular endothelial growth factor [VEGF]) in 27 HbSS patients, 37 HbSC patients and in 42 age and race matched subjects with normal haemoglobin (AA). sP-selectin (P = 0.025) and D-dimers (P < 0.001) were higher in HbSS than in HbSC but there was no difference in VEGF. Sickle cell disease (SCD) is a group of blood disorders typically inherited from a person's parents. The most common type is known as sickle cell anaemia (SCA). It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells.

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. 2019-12-14 · Adakveo (crizanlizumab) is an anti-P-selectin antibody that was developed by Novartis and has been approved by the U.S. Food and Drug Administration (FDA) as a treatment for painful vaso-occlusive crisis events caused by sickle cell disease in patients 16 and older.

PUBLIC HEALTH RELEVANCE: This proposal supports development of SelG1, a humanized antibody to P-selectin, to treat vasoocclusive crisis in sickle cell patients. Sickle cell disease s a devastating, inherited blood disorder that affects over 90,000 persons, primarily African-Americans, in the U.S and vasoocclusive crisis is the leading cause of morbidity, mortality and health care cost in these

2020-07-01 Sickle cell disease (SCD) is the most common genetic hematologic disorder in the United States. The vaso-occlusive characteristics of SCD have been viewed historically as resulting from deformed red blood cells (RBCs) that mechanically obstruct capillaries to produce tissue hypoxia. 1 Present therapies for SCD are geared toward decreasing the concentration or polymerization rate of sickle 2017-12-14 2018-09-17 Data from a post hoc analysis of the phase II SUSTAIN study demonstrated that patients who receive crizanlizumab, a once-a-month, humanized anti-P-selectin monoclonal antibody infusion being investigated for the treatment of sickle cell disease, showed greater reductions of vaso-occlusive crises (VOCs) when they adhere to the treatment protocol, according to a presentation at the 2018 ASH Patients with sickle cell disease may experience pain crises related to P-selectin, which contributes to vaso-occlusion. Would an antibody that blocks bindin P-Selectin is found in the plasma of normal individuals at ng/mL concentrations.
