Protein S Enhances the Phagocytosis of Phosphatidylserine-Exposing Erythrocytes: Implications in Sickle Cell Disease. [PDF]
ABSTRACT The major anticoagulant Protein S (PROS1) also contributes to the phagocytosis of apoptotic cells by bridging exposed phosphatidylserine (PtdSer) to the MerTK receptor on macrophages (efferocytosis). Whether PROS1 is involved in the splenic clearance of PtdSer‐positive senescent and altered erythrocytes such as erythrocyte ghosts (eryghosts ...

FUSION OF INTACT HUMAN ERYTHROCYTES AND ERYTHROCYTE GHOSTS [PDF]
Sendai virus is able to induce the fusion of human erythrocytes. Bivalent cations or ATP are not essential for polyerythrocyte formation. High fusion indices were obtained when Sendai virus was added to cells incubated in the presence of both EDTA and iodoacetic acid.

First Case Report of Precursor-Targeted Immune-Mediated Anaemia in a Dog From Italy Lacking Rubriphagocytosis and With Severe Hyperferraemia: Diagnosis, Treatment, and Clinical Outcome. [PDF]
ABSTRACT Precursor‐targeted immune‐mediated anaemia (PIMA) is an uncommon and poorly understood cause of persistent non‐regenerative anaemia in dogs and cats, characterised by ineffective erythropoiesis and frequently associated with rubriphagocytosis (RP) in bone marrow samples.

MODIFICATION OF ERYTHROCYTE MEMBRANE PROTEINS WITH POLYETHYLENE GLYCOL 1500 [PDF]
The aim of the work was to study the effect of polyethylene glycol PEG-1500 on the Ca2+-ATPase activity and changes in CD44 surface marker expression in human erythrocyte membranes.

SummaryProteins and phospholipids but not zinc were released into the medium containing hemoglobin-free ghosts from dog erythrocytes incubated in peroxidation-inducing agents (ascorbic acid, Fe2+, O2). The content of zinc in the pure ghost depends on the purification procedure; using phosphate buffer it amounted to 62 ± 22 μg/g protein, and using ...

Incorporation of fatty acids into phospholipids of erythrocyte membranes
Incorporation of C14-labeled fatty acids into phospholipids by washed ghosts, prepared from human erythrocytes, required the addition of ATP and was markedly stimulated by MgCl2 and coenzyme A.

Plasmodium falciparum ligand binding to erythrocytes induce alterations in deformability essential for invasion [PDF]
The most lethal form of malaria in humans is caused by Plasmodium falciparum. These parasites invade erythrocytes, a complex process involving multiple ligand-receptor interactions.
