Fluid shear stress stimulates incorporation of hyaluronan into endothelial cell glycocalyx.
Vascular endothelial cells are shielded from direct exposure to flowing blood by the endothelial glycocalyx, a highly hydrated mesh of glycoproteins, sulfated proteoglycans, and associated glycosaminoglycans (GAGs). Recent data indicate that the incorporation of the unsulfated GAG hyaluronan into the endothelial glycocalyx is essential to maintain its permeability barrier properties, and we hyp...
متن کاملThe endothelial glycocalyx
Once thought to be a structure of small size and uncertain significance, the endothelial glycocalyx is now known to be an important regulator of endothelial function. Studies of the systemic vasculature have demonstrated that the glycocalyx forms a substantial in vivo endothelial surface layer (ESL) critical to inflammation, barrier function, and mechanotransduction. The pulmonary ESL is signif...
متن کاملEndothelial Glycocalyx and Cardiopulmonary Bypass.
On the outer surface of a human cell there is a dense layer of complex carbohydrates called glycocalyx, also referred to as glycans or the sugar coating on the cell surface, which is composed of a complex array of oligosaccharide and polysaccharide glucose chains that are covalently bonded to proteoglycans and lipids bound to the cell membrane surface. Studies of an intact endothelial glycocaly...
متن کاملPermeation of the luminal capillary glycocalyx is determined by hyaluronan.
The endothelial cell glycocalyx influences blood flow and presents a selective barrier to movement of macromolecules from plasma to the endothelial surface. In the hamster cremaster microcirculation, FITC-labeled Dextran 70 and larger molecules are excluded from a region extending almost 0.5 μm from the endothelial surface into the lumen. Red blood cells under normal flow conditions are exclude...
متن کاملCan Plasma Hyaluronan and Hyaluronidase Be Used As Markers of the Endothelial Glycocalyx State in Patients with Kidney Disease?
Hyaluronan (HA) is widely spread in the body and is an important component of the extracellular matrix, including the endothelial glycocalyx (EG). Essential for its vasculoprotective function, HA is involved in vascular permeability and many other processes. In patients with kidney disease, plasma HA is higher than expected, but the extent to which plasma HA and its degrading enzyme hyaluronida...
