Anatomical terms of microanatomy

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.

Contents

Endothelial cells in direct contact with blood are called vascular endothelial cells whereas those in direct contact with lymph are known as lymphatic endothelial cells. Vascular endothelial cells line the entire circulatory system, from the heart to the smallest capillaries.

These cells have unique functions that include fluid filtration, such as in the glomerulus of the kidney, blood vessel tone, hemostasis, neutrophil recruitment, and hormone trafficking. Endothelium of the interior surfaces of the heart chambers is called endocardium. An impaired function can lead to serious health issues throughout the body.

Structure

The endothelium is a thin layer of single flat (squamous) cells that line the interior surface of blood vessels and lymphatic vessels. [1]

Endothelium is of mesodermal origin. Both blood and lymphatic capillaries are composed of a single layer of endothelial cells called a monolayer. In straight sections of a blood vessel, vascular endothelial cells typically align and elongate in the direction of fluid flow. [2] [3]

Terminology

The foundational model of anatomy, an index of terms used to describe anatomical structures, makes a distinction between endothelial cells and epithelial cells on the basis of which tissues they develop from, and states that the presence of vimentin rather than keratin filaments separates these from epithelial cells. [4] Many considered the endothelium a specialized epithelial tissue. [5]

The endothelium forms an interface between circulating blood or lymph in the lumen and the rest of the vessel wall. This forms a barrier between vessels and tissues and control the flow of substances and fluid into and out of a tissue. This controls the passage of materials and the transit of white blood cells into and out of the bloodstream. Excessive or prolonged increases in permeability of the endothelium, as in cases of chronic inflammation, may lead to tissue swelling (edema). Altered barrier function is also implicated in cancer extravasation. [6]

Endothelial cells are involved in many other aspects of vessel function, including:

Blood vessel formation

The endothelium is involved in the formation of new blood vessels, called angiogenesis. [11] Angiogenesis is a crucial process for development of organs in the embryo and fetus, [12] as well as repair of damaged areas. [13] The process is triggered by decreased tissue oxygen (hypoxia) or insufficient oxygen tension leading to the new development of blood vessels lined with endothelial cells. Angiogenesis is regulated by signals that promote and decrease the process. These pro- and antiangiogenic signals including integrins, chemokines, angiopoietins, oxygen sensing agents, junctional molecules and endogenous inhibitors. [12] Angiopoietin-2 works with VEGF to facilitate cell proliferation and migration of endothelial cells.

The general outline of angiogenesis is

Host immune response

Endothelial cells express a variety of immune genes in an organ-specific manner. [14] These genes include critical immune mediators and proteins that facilitate cellular communication with hematopoietic immune cells. [15] Endothelial cells encode important features of the structural cell immune response in the epigenome and can therefore respond swiftly to immunological challenges. The contribution to host immunity by non-hematopoietic cells, such as endothelium, is called “structural immunity”. [16]

Clinical significance

Endothelial dysfunction, or the loss of proper endothelial function, is a hallmark for vascular diseases, and is often regarded as a key early event in the development of atherosclerosis. [17] Impaired endothelial function, causing hypertension and thrombosis, is often seen in patients with coronary artery disease, diabetes mellitus, hypertension, hypercholesterolemia, as well as in smokers. Endothelial dysfunction has also been shown to be predictive of future adverse cardiovascular events including stroke, heart disease, and is also present in inflammatory disease such as rheumatoid arthritis, diabetes, and systemic lupus erythematosus. [18] [19]

Endothelial dysfunction is a result of changes in endothelial function. [20] [21] After fat (lipid) accumulation and when stimulated by inflammation, endothelial cells become activated, which is characterized by the expression of molecules such as E-selectin, VCAM-1 and ICAM-1, which stimulate the adhesion of immune cells. [22] Additionally, transcription factors, which are substances which act to increase the production of proteins within cells, become activated; specifically AP-1 and NF-κB, leading to increased expression of cytokines such as IL-1, TNFα and IFNγ, which promotes inflammation. [23] [24] This state of endothelial cells promotes accumulation of lipids and lipoproteins in the intima, leading to atherosclerosis, and the subsequent recruitment of white blood cells and platelets, as well as proliferation of smooth muscle cells, leading to the formation of a fatty streak. The lesions formed in the intima, and persistent inflammation lead to desquamation of endothelium, which disrupts the endothelial barrier, leading to injury and consequent dysfunction. [25] In contrast, inflammatory stimuli also activate NF-κB-induced expression of the deubiquitinase A20 (TNFAIP3), which has been shown to intrinsically repair the endothelial barrier. [26]

One of the main mechanisms of endothelial dysfunction is the diminishing of nitric oxide, often due to high levels of asymmetric dimethylarginine, which interfere with the normal L-arginine-stimulated nitric oxide synthesis and so leads to hypertension. The most prevailing mechanism of endothelial dysfunction is an increase in reactive oxygen species, which can impair nitric oxide production and activity via several mechanisms. [27] The signalling protein ERK5 is essential for maintaining normal endothelial cell function. [28] A further consequence of damage to the endothelium is the release of pathological quantities of von Willebrand factor, which promote platelet aggregation and adhesion to the subendothelium, and thus the formation of potentially fatal thrombi.

Angiosarcoma is cancer of the endothelium and is rare with only 300 cases per year in the US. [29] However it generally has poor prognosis with a five-year survival rate of 35%. [30]

Research

Endothelium in cancer

It has been recognised that endothelial cells building tumour vasculature have distinct morphological characteristics, different origin compared to physiological endothelium, and distinct molecular signature, which gives an opportunity for implementation of new biomarkers of tumour angiogenesis and could provide new anti-angiogenic druggable targets. [31]

Endothelium in diet

A healthy diet abundant in fruits and vegetables has a beneficial impact on endothelial function, whilst a diet high in red and processed meats, fried foods, refined grains and processed sugar increases adhesion endothelial cells and atherogenic promoters. [32] High-fat diets adversely affect the endothelial function. [33]

A Mediterranean diet has been found to improve endothelial function in adults which can reduce risk of cardiovascular disease. [34] [35] Walnut consumption improves endothelial function. [36] [37]

Endothelium in Covid-19

In April 2020, the presence of viral elements in endothelial cells of 3 patients who had died of COVID-19 was reported for the first time. The researchers from the University of Zurich and Harvard Medical School considered these findings to be a sign of a general endotheliitis in different organs, an inflammatory response of the endothelium to the infection that can lead or at least contribute to multi-organ failure in Covid-19 patients with comorbidities such as diabetes mellitus, hypertension and cardiovascular disease. [38] [39]

History

In 1865, the Swiss anatomist Wilhelm His Sr. first coined the term “endothelium”. [40] In 1958, A. S. Todd of the University of St Andrews demonstrated that endothelium in human blood vessels have fibrinolytic activity. [41] [42]

Blood vessels are the tubular structures of a circulatory system that transport blood throughout a vertebrate's body. Blood vessels transport blood cells, nutrients, and oxygen to most of the tissues of a body. They also take waste and carbon dioxide away from the tissues. Some tissues such as cartilage, epithelium, and the lens and cornea of the eye are not supplied with blood vessels and are termed avascular.

<span class="mw-page-title-main">Angiogenesis</span> Blood vessel formation, when new vessels emerge from existing vessels

Angiogenesis is the physiological process through which new blood vessels form from pre-existing vessels, formed in the earlier stage of vasculogenesis. Angiogenesis continues the growth of the vasculature mainly by processes of sprouting and splitting, but processes such as coalescent angiogenesis, vessel elongation and vessel cooption also play a role. Vasculogenesis is the embryonic formation of endothelial cells from mesoderm cell precursors, and from neovascularization, although discussions are not always precise. The first vessels in the developing embryo form through vasculogenesis, after which angiogenesis is responsible for most, if not all, blood vessel growth during development and in disease.

Atherosclerosis is a pattern of the disease arteriosclerosis, characterized by development of abnormalities called lesions in walls of arteries. This is a chronic inflammatory disease involving many different cell types and driven by elevated levels of cholesterol in the blood. These lesions may lead to narrowing of the arterial walls due to buildup of atheromatous plaques. At the onset there are usually no symptoms, but if they develop, symptoms generally begin around middle age. In severe cases, it can result in coronary artery disease, stroke, peripheral artery disease, or kidney disorders, depending on which body part(s) the affected arteries are located in the body.

<span class="mw-page-title-main">Vasodilation</span> Widening of blood vessels

Vasodilation, also known as vasorelaxation, is the widening of blood vessels. It results from relaxation of smooth muscle cells within the vessel walls, in particular in the large veins, large arteries, and smaller arterioles. Blood vessel walls are composed of endothelial tissue and a basal membrane lining the lumen of the vessel, concentric smooth muscle layers on top of endothelial tissue, and an adventitia over the smooth muscle layers. Relaxation of the smooth muscle layer allows the blood vessel to dilate, as it is held in a semi-constricted state by sympathetic nervous system activity. Vasodilation is the opposite of vasoconstriction, which is the narrowing of blood vessels.

Endothelial stem cells (ESCs) are one of three types of stem cells found in bone marrow. They are multipotent, which describes the ability to give rise to many cell types, whereas a pluripotent stem cell can give rise to all types. ESCs have the characteristic properties of a stem cell: self-renewal and differentiation. These parent stem cells, ESCs, give rise to progenitor cells, which are intermediate stem cells that lose potency. Progenitor stem cells are committed to differentiating along a particular cell developmental pathway. ESCs will eventually produce endothelial cells (ECs), which create the thin-walled endothelium that lines the inner surface of blood vessels and lymphatic vessels. The blood vessels include arteries and veins. Endothelial cells can be found throughout the whole vascular system and they also play a vital role in the movement of white blood cells

RAGE, also called AGER, is a 35 kilodalton transmembrane receptor of the immunoglobulin super family which was first characterized in 1992 by Neeper et al. Its name comes from its ability to bind advanced glycation endproducts (AGE), which include chiefly glycoproteins, the glycans of which have been modified non-enzymatically through the Maillard reaction. In view of its inflammatory function in innate immunity and its ability to detect a class of ligands through a common structural motif, RAGE is often referred to as a pattern recognition receptor. RAGE also has at least one other agonistic ligand: high mobility group protein B1 (HMGB1). HMGB1 is an intracellular DNA-binding protein important in chromatin remodeling which can be released by necrotic cells passively, and by active secretion from macrophages, natural killer cells, and dendritic cells.

Vascular disease is a class of diseases of the vessels of the circulatory system in the body, including blood vessels – the arteries and veins, and the lymphatic vessels. Vascular disease is a subgroup of cardiovascular disease. Disorders in this vast network of blood and lymph vessels can cause a range of health problems that can sometimes become severe, and fatal. Coronary heart disease for example, is the leading cause of death for men and women in the United States.

Angiopoietin is part of a family of vascular growth factors that play a role in embryonic and postnatal angiogenesis. Angiopoietin signaling most directly corresponds with angiogenesis, the process by which new arteries and veins form from preexisting blood vessels. Angiogenesis proceeds through sprouting, endothelial cell migration, proliferation, and vessel destabilization and stabilization. They are responsible for assembling and disassembling the endothelial lining of blood vessels. Angiopoietin cytokines are involved with controlling microvascular permeability, vasodilation, and vasoconstriction by signaling smooth muscle cells surrounding vessels. There are now four identified angiopoietins: ANGPT1, ANGPT2, ANGPTL3, ANGPT4.

They are considered to be larger, on average, than intracellularly-generated EVs known as exosomes. Microvesicles play a role in intercellular communication and can transport molecules such as mRNA, miRNA, and proteins between cells.

<span class="mw-page-title-main">Endothelial NOS</span> Protein and coding gene in humans

Endothelial NOS (eNOS), also known as nitric oxide synthase 3 (NOS3) or constitutive NOS (cNOS), is an enzyme that in humans is encoded by the NOS3 gene located in the 7q35-7q36 region of chromosome 7. This enzyme is one of three isoforms that synthesize nitric oxide (NO), a small gaseous and lipophilic molecule that participates in several biological processes. The other isoforms include neuronal nitric oxide synthase (nNOS), which is constitutively expressed in specific neurons of the brain and inducible nitric oxide synthase (iNOS), whose expression is typically induced in inflammatory diseases. eNOS is primarily responsible for the generation of NO in the vascular endothelium, a monolayer of flat cells lining the interior surface of blood vessels, at the interface between circulating blood in the lumen and the remainder of the vessel wall. NO produced by eNOS in the vascular endothelium plays crucial roles in regulating vascular tone, cellular proliferation, leukocyte adhesion, and platelet aggregation. Therefore, a functional eNOS is essential for a healthy cardiovascular system.

20-Hydroxyeicosatetraenoic acid, also known as 20-HETE or 20-hydroxy-5Z,8Z,11Z,14Z-eicosatetraenoic acid, is an eicosanoid metabolite of arachidonic acid that has a wide range of effects on the vascular system including the regulation of vascular tone, blood flow to specific organs, sodium and fluid transport in the kidney, and vascular pathway remodeling. These vascular and kidney effects of 20-HETE have been shown to be responsible for regulating blood pressure and blood flow to specific organs in rodents; genetic and preclinical studies suggest that 20-HETE may similarly regulate blood pressure and contribute to the development of stroke and heart attacks. Additionally the loss of its production appears to be one cause of the human neurological disease, hereditary spastic paraplegia. Preclinical studies also suggest that the overproduction of 20-HETE may contribute to the progression of certain human cancers, particularly those of the breast.

This condition, which protects the tumor from the immune system, is the result of exposure to angiogenic growth factors.
