Summary
Angiotensin-converting enzyme 2 (ACE2) is crucial for organ homeostasis and links the renin-angiotensin system
Area of Science:
- Biochemistry
- Physiology
- Pathology
Background:
- The discovery of angiotensin-converting enzyme 2 (ACE2) in 2000 marked a significant advancement in understanding the renin-angiotensin system.
- ACE2 plays a pivotal role in connecting the classical renin-angiotensin system (angiotensin II/AT1 receptor) with its protective arm (angiotensin 1-7/Mas receptor).
Purpose of the Study:
- To review the literature on the protective functions of ACE2 in various organs.
- To provide insight into ACE2's role in the pathophysiology of coronavirus diseases 2019 (COVID-19).
Main Methods:
- Literature review focusing on ACE2's role in organ homeostasis.
- Review of recent literature concerning ACE2 in the context of COVID-19.
Main Results:
- ACE2 is a key enzyme in the protective arm of the renin-angiotensin system.
- ACE2 is vital for maintaining homeostasis in organs including the brain, cardiovascular system, kidneys, lungs, and digestive tract.
- Emerging literature highlights ACE2's significant role in the course of COVID-19.
Conclusions:
- ACE2 is a critical enzyme with protective functions across multiple organ systems.
- Understanding ACE2's role is essential for comprehending both normal physiology and the pathogenesis of diseases like COVID-19.

Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors

Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...

Antihypertensive Drugs: Direct Renin Inhibitors

The renin-angiotensin-aldosterone system (RAAS) is an intricate physiological pathway involving numerous enzymes and hormones, including renin, angiotensin-converting enzyme (ACE), angiotensin I and II, and aldosterone. Imbalances within this system increase the production of angiotensin II and aldosterone. Increased angiotensin II levels promote vasoconstriction and blood pressure elevation. Concurrently, higher aldosterone levels stimulate sodium and water reabsorption in the kidneys,...

Hypertension II: Pathophysiology
268
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Antihypertensive Drugs: Angiotensin II Receptor Blockers
2.0K
In the renin-angiotensin-aldosterone system, a hormone called angiotensin II plays a crucial role. It binds to the AT1 receptors in vascular smooth muscles coupled with Gq proteins. The activation of these receptors activates an enzyme called phospholipase C, which releases two molecules: inositol trisphosphate and diacylglycerol. These molecules cause a chain reaction that leads to the phosphorylation of myosin light chains and promotes interaction between actin and myosin, leading to smooth...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.

Hormonal Regulation
34.7K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.
