In vivo red blood cell sickling and mechanism of recovery in whiting, Merlangius merlangus.
Haemoglobin concentrations in vertebrate red blood cells are so high that in human sickle cell disease a single surface amino acid mutation can result in formation of large insoluble haemoglobin aggregates at low oxygen levels, causing peculiar cell deformations or 'sickling'. This may cause vascular occlusion and thereby severe pain, organ failure and death. Here, using light and transmission ...
متن کاملRate of Sickling of Red Cells during Deoxygenation of Blood from Persons with Various Sickling Disorders.
By SAMUEL CIIARAcIIE AND C. LOCKARD CONLEY S ICKLED ERYTHROCYTES are rapidly removed for the circulation, an occurrence that accounts for the hemolytic aspects of sickle cell disease.’ Anemia is a usual result but is often asymptomatic and is not the principal cause of the high morbidity and reduced life span of affected persons. Many of the clinical manifestations of sicklemia have been attrib...
متن کاملRED CELLS Dipyridamole inhibits sickling-induced cation fluxes in sickle red blood cells
Sickling-induced cation fluxes contribute to cellular dehydration of sickle red blood cells (SS RBCs), which in turn potentiates sickling. This study examined the inhibition by dipyridamole of the sicklinginduced fluxes of Na1, K1, and Ca11 in vitro. At 2% hematocrit, 10 mM dipyridamole inhibited 65% of the increase in net fluxes of Na1 and K1 produced by deoxygenation of SS RBCs. Sickle-induce...
متن کاملRed cells shrink during sickling.
Rapid transformatIon of discoid hemoglobin SS erythrocytes into grossly distorted sickled forms suggests alteration of surface/volume ratio. We, therefore, examined the effect of deoxygenation on red cell volume. ‘31llaholed albumin was used as a marker of plasma volume in normal (Hb AA), sickle (Hb SS), and sickle-C (Hb SC) blood. Heparinized blood was incubated for 30 mm at 37#{176}Cin a tpno...
متن کاملβ-Globin Sleeping Beauty Transposon Reduces Red Blood Cell Sickling in a Patient-Derived CD34+-Based In Vitro Model
The ultimate goal of gene therapy for sickle cell anemia (SCA) is an improved phenotype for the patient. In this study, we utilized bone marrow from a sickle cell patient as a model of disease in an in vitro setting for the hyperactive Sleeping Beauty transposon gene therapy system. We demonstrated that mature sickle red blood cells containing hemoglobin-S and sickling in response to metabisulf...
