The endothelium (pl.: endothelia) is a single layer of squamous endothelial cells that line the interior surface of blood vessels and lymphatic vessels. [1] The endothelium forms an interface between circulating blood or lymph in the lumen and the rest of the vessel wall.
In anatomy the term reticuloendothelial system (abbreviated RES), often associated nowadays with the mononuclear phagocyte system (MPS), was employed by the beginning of the 20th century to denote a system of specialised cells that effectively clear colloidal vital stains (so called because they stain living cells) from the blood circulation.
Liver sinusoidal endothelial cells (LSECs) form the lining of the smallest blood vessels in the liver, also called the hepatic sinusoids. LSECs are highly specialized endothelial cells with characteristic morphology and function. They constitute an important part of the reticuloendothelial system (RES).
Damage to endothelium is an early abnormality in the development of scleroderma, and this, too, seems to be due to collagen accumulation by fibroblasts, although direct alterations by cytokines, platelet adhesion, and a type II hypersensitivity reaction similarly have been implicated.
There are good reasons this fish gets a lot of love from health professionals. "Salmon is among the best choices for healthy fish. It's high in omega-3s — fats that help cardiovascular and brain ...
Caveolae can also serve as mechanosensors in various cell types. In endothelial cells, caveolae are involved in flow sensation. Chronic exposure to the flow stimulus leads to increased levels of caveolin Cav1 in plasma membrane, its phosphorylation, activation of eNOS signaling enzyme and to remodeling of blood vessels.
This most commonly occurs within the spleen, but also can occur in the reticuloendothelial system or mechanically (prosthetic valve damage). [2] Hemolytic anemia accounts for 5% of all existing anemias. [2] It has numerous possible consequences, ranging from general symptoms to life-threatening systemic effects. [2]
Italy’s former national carrier Alitalia has started procedures for the collective dismissal of its remaining 2,059 employees, its administrators told unions. The move comes as the successor to ...
