Role of fibrinogen–erythrocyte and erythrocyte–erythrocyte adhesion on cardiovascular pathologies [PDF]

Annals of Medicine, 2021
Cardiovascular pathologies are the major cause of death worldwide. Erythrocyte aggregation is an indicator of cardiovascular risk, which is influenced by high plasma fibrinogen levels. Our main goals were to understand how fibrinogen–erythrocyte binding influences erythrocyte aggregation and how it constitutes a cardiovascular risk factor in essential ...

Erythrocytes and Erythropoietin [PDF]

International Journal of Cell Biology, 2011
This special issue focuses on erythrocytes and erythropoietin including original research and review articles on the cellular physiology of erythrocytes and of erythrocyte-associated disorders. Moreover, the special issue includes papers on the action of erythropoietin and hypoxia-inducible factors on a cellular level.

Erythrocyte sedimentation: Fracture and collapse of a high-volume-fraction soft-colloid gel [PDF]

Phys. Rev. Lett. 128, 088101 (2022), 2021
The erythrocyte sedimentation rate is one of the oldest medical diagnostic methods whose physical mechanisms remain debatable up to date. Using both light microscopy and mesoscale cell-level simulations, we show that erythrocytes form a soft-colloid gel.

Streptococcus pneumoniae invades erythrocytes and utilizes them to evade human innate immunity. [PDF]

PLoS ONE, 2013
Streptococcus pneumoniae, a Gram-positive bacterium, is a major cause of invasive infection-related diseases such as pneumonia and sepsis. In blood, erythrocytes are considered to be an important factor for bacterial growth, as they contain abundant ...

Erythrocyte sedimentation: Effect of aggregation energy on gel structure during collapse [PDF]

Phys. Rev. E 105, 024610 (2022), 2021
The erythrocyte (or red blood cell) sedimentation rate (ESR) is commonly interpreted as a measure of cell aggregation and as a biomarker of inflammation. It is well known that an increase of fibrinogen concentration, an aggregation-inducing protein for erythrocytes, leads to an increase of the sedimentation rate of erythrocytes, which is generally ...

Meningeal lymphatics clear erythrocytes that arise from subarachnoid hemorrhage

Nature Communications, 2020
Extravasated erythrocytes in cerebrospinal fluid (CSF) critically contribute to the pathogenesis of subarachnoid hemorrhage (SAH). Meningeal lymphatics have been reported to drain macromolecules and immune cells from CSF into cervical lymph nodes (CLNs).

Erythrocytes as Carriers: From Drug Delivery to Biosensors

Pharmaceutics, 2020
Drug delivery using natural biological carriers, especially erythrocytes, is a rapidly developing field. Such erythrocytes can act as carriers that prolong the drug’s action due to its gradual release from the carrier; as bioreactors with encapsulated ...

EFFECT OF OLIGOSACCHARIDES ON ENZYMES OF CARBOHYDRATE METABOLISM AND ANTIOXIDANT PROTECTION IN IN VITRO TREATED ERYTHROCYTES UNDER CONDITIONS OF HYPERGLYCEMIA [PDF]

Journal of IMAB, 2021
Introduction: The purpose of this experiment is to examine the effect of different oligosaccharides with proven prebiotic effects on enzymes of carbohydrate metabolism and the antioxidant protection of erythrocytes in vitro under conditions of ...

Interaction of Colchicine-Site Ligands With the Blood Cell-Specific Isotype of β-Tubulin—Notable Affinity for Benzimidazoles

Frontiers in Cell and Developmental Biology, 2022
Tubulin, the main component of microtubules, is an α-β heterodimer that contains one of multiple isotypes of each monomer. Although the isotypes of each monomer are very similar, the beta tubulin isotype found in blood cells is significantly divergent in

Anisotropic short-range attractions precisely model branched erythrocyte aggregates [PDF]

Soft Matter, 2023, 19, 8717-8728, 2023
Homogeneous suspensions of red blood cells (RBCs or erythrocytes) in blood plasma are unstable in the absence of driving forces and form elongated stacks, called rouleau. These erythrocyte aggregates are often branched porous networks -- a feature that existing red blood cell aggregation models and simulations fail to predict exactly. Here we establish
