Erythrocyte-erythrocyte aggregation dynamics under shear flow [PDF]
Phys. Rev. Fluids 6, 023602 (2021), 2020 Red blood cells (RBCs) -- erythrocytes -- suspended in plasma tend to aggregate and form rouleaux. During aggregation the first stage consists in the formation of RBC doublets [Blood cells, molecules, and diseases 25, 339 (1999)]. While aggregates are normally dissociated by moderate flow stresses, under some pathological conditions the aggregation ...

A mathematical model of fibrinogen-mediated erythrocyte–erythrocyte adhesion
Communications Biology, 2023 AbstractErythrocytes are deformable cells that undergo progressive biophysical and biochemical changes affecting the normal blood flow. Fibrinogen, one of the most abundant plasma proteins, is a primary determinant for changes in haemorheological properties, and a major independent risk factor for cardiovascular diseases.

Effect of hydrogen peroxide on normal and acatalasemic mouse erythrocytes
Toxicology Reports, 2020 Objectives: Normal and acatalasemic mouse erythrocytes were used to clarify the relationship between oxidative damage in H2O2-treated erythrocytes and catalase activity.

Beilstein Journal of Nanotechnology, 2015 A novel and facile method was developed to produce hybrid graphene oxide (GO)–polyelectrolyte (PE) capsules using erythrocyte cells as templates. The capsules are easily produced through the layer-by-layer technique using alternating polyelectrolyte ...

Vaccines, 2019 Teleost red blood cells (RBCs) are nucleated and therefore can propagate cellular responses to exogenous stimuli. RBCs can mount an immune response against a variety of fish viruses, including the viral septicemia hemorrhagic virus (VHSV), which is one ...

Optical tweezer for probing erythrocyte membrane deformability [PDF]
Appl. Phys. Lett. 95, 233703 (2009), 2010 We report that the average rotation speed of optically trapped crenated erythrocytes is direct signature of their membrane deformability. When placed in hypertonic buffer, discocytic erythrocytes are subjected to crenation. The deformation of cells brings in chirality and asymmetry in shape that make them rotate under the scattering force of a linearly

Malaria's deadly grip: cytoadhesion of Plasmodium falciparum‐infected erythrocytes
Cellular Microbiology, 2013 Cytoadhesion of Plasmodium falciparum‐infected erythrocytes to host microvasculature is a key virulence determinant. Parasite binding is mediated by a large family of clonally variant adhesion proteins, termed P. falciparum erythrocyte membrane protein 1

Softlithography in Chemical Sensing – Analytes from Molecules to Cells
Sensors, 2005 Imprinting is a flexible and straightforward technique to generate selective sensormaterials e.g. for mass-sensitive detection. Inherently, the strategy suits both molecularanalytes and entire micro organisms or cells. Imprinted polyurethanes e.g.

Proceedings of the National Academy of Sciences of the United States of America, 2012 Research into the aetiological agent of the most widespread form of severe malaria, Plasmodium falciparum, has benefitted enormously from the ability to culture and genetically manipulate blood-stage forms of the parasite in vitro.

Interactions Between Aerolysin, Erythrocytes, and Erythrocyte Membranes [PDF]
Infection and Immunity, 1975 Aerolysin, a hemolytic and lethal exotoxin of Aeromonas hydrophila , was analyzed for amino acids. Assuming 8 histidine residues/mol, the purified toxic protein has, by summation, a molecular weight of 49,000, a value in agreement with earlier estimates by other methods.
