Spinach Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) large (rbcL) and small (rbcS) subunits were separated by SDS-PAGE, and protein amount and purity were determined by Bradford assay. Polyclonal antibodies against rbcL and rbcS subunit were generated in female BALB/c mice and had no cross-reaction with each other. A total of 81 microg antigens were used and 0.3 ml anti-sera with t...
Sickle cell trait (SCT) is a condition in which an individual inherits one sickle hemoglobin gene (HbS) and one normal beta hemoglobin gene (HbA). It has been hypothesized that under extreme physical stress, the compromised mechanical properties of the red blood cells (RBCs) may be the underlying mechanism of clinical complications of sickle cell trait individuals. However, whether sickle cell ...
We developed modified RBCs to serve as carriers for systemic delivery of a wide array of payloads. These RBCs contain modified proteins on their plasma membrane, which can be labeled in a sortase-catalyzed reaction under native conditions without inflicting damage to the target membrane or cell. Sortase accommodates a wide range of natural and synthetic payloads that allow modification of RBCs ...
Oxidative stress has been implicated in the triggering of apoptosis in neutrophils. Because red blood cells (RBCs) are well known to scavenge oxidants including H2O2, we tested the hypothesis that RBCs inhibit apoptosis of neutrophils by reducing intracellular oxidative stress. Apoptosis of neutrophils was evaluated by light microscopy and DNA gel electrophoresis. We found that coculture with R...
The transition of red blood cells (RBCs) from primitive to definitive erythropoiesis is conserved across vertebrates. In anuran amphibians, the larval RBCs from primitive erythropoiesis are replaced by adult RBCs from definitive erythropoiesis during metamorphosis. The molecular mechanisms by which the primitive (larval) blood cells are specifically removed from circulation are not yet understo...
This study determined and compared rates and mechanisms of lactate transport in red blood cells (RBCs) of persons with 1) sickle cell disease (HbSS), 2) sickle cell trait (HbAS), and 3) a control group (HbAA). Blood samples were drawn from 30 African-American volunteers (10 HbSS, 10 HbAS, 10 HbAA). Lactate influx into RBCs was measured by using [14C]lactate at six (2, 5, 10, 15, 25, and 40 mM) ...
RBCs undergo numerous changes during storage and stored RBCs may induce adverse effects, ultimately resulting in organ injury in transfusion recipients. We tested the hypothesis that the addition of SP to stored RBCs would improve the quality of the stored RBCs and mitigate liver injury after transfusion in a murine model. RBCs were harvested from C57BL/6J mice and stored for 14 days in CPDA-1 ...
Phospholipid asymmetry is well maintained in erythrocyte (RBC) membranes with phosphatidylserine (PS) exclusively present in the inner leaflet. The appearance of PS on the surface of the cell can have major physiologic consequences, including increased cell-cell interactions. Because increased adherence of PSexposing RBCs to endothelial cells (ECs) may be pathologically important in hemoglobino...
Reported findings of elevated total calcium (Ca) contents in erythrocytes (RBCs) from patients with beta-thalassemia intermedia (beta-TI) prompted the question of whether the state and transport of Ca in these RBCs are similar to those in sickle cell anemia (SS) RBCs where the increased Ca is compartmentalized in endocytic inside-out vesicles and extracted by exposure of the cells to the Ca ion...
Some fish viruses, such as piscine orthoreovirus and infectious Background: salmon anemia virus, target red blood cells (RBCs), highly replicate inside them and induce an immune response. However, the implications of RBCs in the context of birnavirus infection (i.e, infectious pancreatic necrosis virus (IPNV)) have not yet been studied. trout RBCs were obtained from peripheral blood, ficoll Met...
