Transducer Mechanism: Enzyme-Linked Receptors

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.
Major types that are helpful drug targets include:

Heart Failure II: Pathophysiology

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Hormonal Regulation of Blood Pressure

Hormonal Regulation of Blood Pressure

Endocrinal or hormonal intervention in the cardiovascular system is predominantly exerted by the catecholamines - epinephrine and norepinephrine, as well as a slew of hormones that interact with renal function to modulate blood volume.
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme (ECE). Of...

Summary

Cardiac natriuretic peptides, ANP and BNP, show promise in diagnosing dyspnoea and guiding heart failure treatment. Their levels may also serve as prognostic indicators in at-risk populations.

Background:

Cardiac natriuretic peptides, including atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP), have established roles in cardiovascular physiology and pathophysiology.
However, their full potential in clinical diagnosis, prognosis, and therapeutics across various disorders remains to be fully elucidated.

Purpose of the Study:

To explore the diagnostic, prognostic, and therapeutic potential of circulating natriuretic peptides (ANP and BNP) in diverse clinical settings.
To investigate the clinical utility of a circulating BNP signal peptide segment.

Main Methods:

Review and prediction based on existing knowledge of natriuretic peptide roles.
Discussion of the presence and potential clinical significance of a BNP signal peptide fragment in circulation.

Main Results:

Predicted increasing diagnostic utility of ANP and BNP levels in patients with dyspnoea.
Anticipated usefulness of these peptides in guiding pharmacotherapy for heart failure and managing patients on renal dialysis.
Projected value of peptide levels as prognostic indicators in at-risk populations (e.g., diabetes, hypertension) but not the general population.
Likely therapeutic application of natriuretic peptides in acute myocardial infarction, with less certainty for heart failure.

Conclusions:

Circulating natriuretic peptides (ANP and BNP) are predicted to have significant clinical utility in diagnosis and management of cardiovascular and renal conditions.
Further research into the BNP signal peptide segment may reveal additional clinical applications.
