Erythrocyte Aging, Protection via Vesiculation: An Analysis Methodology via Oscillatory Flow [PDF]

Frontiers in Physiology, 2018
We demonstrate that erythrocyte deformations, specifically of a type as occur in splenic flow (Zhu et al., 2017), and of the type that promote vesiculation can be caused by simple, yet tailored, oscillatory shear flow. We show that such oscillatory shear

Glycophorin-C sialylation regulates Lu/BCAM adhesive capacity during erythrocyte aging [PDF]

Blood Advances, 2018
: Lutheran/basal cell adhesion molecule (Lu/BCAM) is a transmembrane adhesion molecule expressed by erythrocytes and endothelial cells that can interact with the extracellular matrix protein laminin-α5.

P. falciparum Invasion and Erythrocyte Aging [PDF]

Cells
Plasmodium parasites need to find red blood cells (RBCs) that, on the one hand, expose receptors for the pathogen ligands and, on the other hand, maintain the right geometry to facilitate merozoite attachment and entry into the red blood cell.

Erythrocyte levels of n-3 polyunsaturated fatty acids and incidence of frailty after a 6-year follow-up: the Korean frailty and aging cohort study [PDF]

Frontiers in Nutrition
Previous studies have shown that the blood levels of n-3 polyunsaturated fatty acids (PUFA) are inversely associated with the prevalence of frailty, but associations with frailty incidence remain unknown.

Comparing Nanomechanical Properties and Membrane Roughness Along the Aging of Human Erythrocytes

Methods and Protocols
Erythrocyte (RBC) aging involves significant structural and nanomechanical alterations crucial to their function. This study aims to bridge the gap between analyses based on statistical morphometric parameters, e.g., membrane roughness, and those based ...

Erythrocyte adenosine A2B receptor prevents cognitive and auditory dysfunction by promoting hypoxic and metabolic reprogramming.

PLoS Biology, 2021
Hypoxia drives aging and promotes age-related cognition and hearing functional decline. Despite the role of erythrocytes in oxygen (O2) transport, their role in the onset of aging and age-related cognitive decline and hearing loss (HL) remains ...

Comparison of Hemoglobin Correction Effects According to Storage Period and Other Factors in the Transfusion of Packed Red Blood Cells in Neonatal Intensive Care Unit Patients [PDF]

Neonatal Medicine, 2018
Purpose Preterm infants frequently require red blood cell (RBC) transfusions in neonatal intensive care units (NICU). Storage RBCs undergo many changes during storage periods.

Variations on fibrinogen-erythrocyte interactions during cell aging. [PDF]

PLoS ONE, 2011
Erythrocyte hyperaggregation, a cardiovascular risk factor, is considered to be caused by an increase in plasma adhesion proteins, particularly fibrinogen.
