The pathogenesis of
hypertension
, as a multifactorial trait, is complex.
High blood pressure
levels, in turn, concur with the development of cardiovascular damage. Abnormalities of several neurohormonal mechanisms controlling blood pressure homeostasis and cardiovascular remodeling can contribute to these pathological conditions. The natriuretic peptide (NP) family (including ANP (atrial natriuretic peptide), BNP (brain natriuretic peptide), and CNP (C-type natriuretic peptide)), the NP receptors (NPRA,
NPRB
, and NPRC), and the related protease convertases (furin, corin, and PCSK6) constitute the NP system and represent relevant protective mechanisms toward the development of
hypertension
and associated conditions, such as atherosclerosis, stroke, myocardial infarction, heart failure, and renal injury. Initially, several experimental studies performed in different animal models demonstrated a key role of the NP system in the development of
hypertension
. Importantly, these studies provided relevant insights for a better comprehension of the pathogenesis of
hypertension
and related cardiovascular phenotypes in humans. Thus, investigation of the role of NPs in
hypertension
offers an excellent example in translational medicine. In this review article, we will summarize the most compelling evidence regarding the molecular mechanisms underlying the physiological and pathological impact of NPs on blood pressure regulation and on
hypertension
development. We will also discuss the protective effect of NPs toward the increased susceptibility to hypertensive target organ damage.

The natriuretic peptide (NP) system is composed of 3 distinct peptides (atrial natriuretic peptide or ANP, B-type natriuretic peptide or BNP, and C-type natriuretic peptide or CNP) and 3 receptors (natriuretic peptide receptor-A or NPR-A or particulate guanynyl cyclase-A natriuretic peptide receptor-B or
NPR-B
or particulate guanynyl cyclase-B, and natriuretic peptide receptor-C or NPR-C or clearance receptor). ANP and BNP function as defense mechanisms against ventricular stress and the deleterious effects of volume and pressure overload on the heart. Although the role of NPs in cardiovascular homeostasis has been extensively studied and well established, much remains uncertain about the signaling pathways in pathological states like heart failure, a state of impaired natriuretic peptide function. Elevated levels of ANP and BNP in heart failure correlate with disease severity and have a prognostic value. Synthetic ANP and BNP have been studied for their therapeutic role in
hypertension
and heart failure, and promising trials are under way. In recent years, the expression of ANP and BNP in human adipocytes has come to light. Through their role in promotion of adipocyte browning, lipolysis, lipid oxidation, and modulation of adipokine secretion, they have emerged as key regulators of energy consumption and metabolism. NPR-A signaling in skeletal muscles and adipocytes is emerging as pivotal to the maintenance of long-term insulin sensitivity, which is disrupted in obesity and reduced glucose-tolerance states. Genetic variants in the genes encoding for ANP and BNP have been associated with a favorable cardiometabolic profile. In this review, we discuss several pathways that have been proposed to explain the role of NPs as endocrine networkers. There is much to be explored about the therapeutic role of NPs in improving metabolic milieu.

Natriuretic peptides are peptide hormones which are involved in the regulation of blood pressure, water-mineral balance and multiple metabolic processes. The beginning of research on this group of hormones starts in 1981, when the deBold and collaborators discovered ANP. Eight natriuretic peptides have been described so far: ANP, BNP, CNP, DNP, urodilatin, uroguanylin, osteocrin, musculin and three receptors: NPR-A,
NPR-B
and NPR-C thanks to which these hormones accomplish their physiological functions. Determination of natriuretic peptide concentration in plasma is used in the diagnosis and treatment of heart failure and pulmonary embolism. Research results indicate that the determination of natriuretic peptides concentration in plasma may also be important in the acute coronary syndromes, subclinical complications of
hypertension
and atrial fibrillation. The concentration of natriuretic peptides is changing in many diseases. The beneficial effects of natriuretic peptides have led to the production of drugs that are their synthetic derivatives. These drugs are mainly used among patients with heart failure. Research is currently underway on the efficacy and safety of other synthetic natriuretic peptides.
