Special Issue Information

Dear colleagues,

Hypertension is a highly prevalent condition worldwide and a leading risk factor for cardiovascular diseases (CVD) and related complications. It occurs as a common comorbidity to several diseases associated with increased CVD risk, including, but not limited to, metabolic disorders, obstructive sleep apnoea syndrome, immune-mediated diseases, like rheumatoid arthritis and periodontal disorders, and cancer. In recent years, evidence has accumulated in support of the role of the immune system in the pathogenesis of hypertension and atherogenesis, providing new insights into the understanding of accelerated cardiovascular pathology in the presence of inflammation. Acute and chronic inflammation are both responsible for an increased risk of CVD. In an acute setting, including acute infections, increased sympathetic activity, tachycardia, hypoxia, thrombophilia, and the release of inflammatory cytokines contribute to increased vascular tone and destabilization of atheromatous plaques. On the other hand, the inappropriate persistence of immune system activation that occurs during chronic inflammation, typically associated with redox unbalance and impaired metabolic pathways, appears to contribute to the establishment and/or progression of traditional cardiovascular risk factors, including hypertension. The role of the human virome and microbiome in this scenario is intriguing, and the therapeutic implications of correcting dysbiosis in different settings are under investigation. This Special Issue is dedicated to the impact of acute and chronic inflammation—and related hormonal, metabolic, and neurological events—on traditional and novel cardiovascular risk factors, welcoming studies that help clarify the molecular bases of increased CVD risk in the presence of immune system activation, and the potential therapeutic approaches to the problem.

Abstract
Inflammasomes are components of the innate immune response that have recently emerged as crucial controllers of tissue homeostasis. In particular, the nucleotide-binding domain, leucine-rich-containing (NLR) family pyrin domain containing 3 (NLRP3) inflammasome is a complex platform involved in the activation of caspase-1 and [...] Read more.
Inflammasomes are components of the innate immune response that have recently emerged as crucial controllers of tissue homeostasis. In particular, the nucleotide-binding domain, leucine-rich-containing (NLR) family pyrin domain containing 3 (NLRP3) inflammasome is a complex platform involved in the activation of caspase-1 and the maturation of interleukin (IL)-1β and IL-18, which are mainly released via pyroptosis. Pyroptosis is a caspase-1-dependent type of cell death that is mediated by the cleavage of gasdermin D and the subsequent formation of structurally stable pores in the cell membrane. Through these pores formed by gasdermin proteins cytosolic contents are released into the extracellular space and act as damage-associated molecular patterns, which are pro-inflammatory signals. Inflammation is a main contributor to the development of hypertension and it also is known to stimulate fibrosis and end-organ damage. Patients with essential hypertension and animal models of hypertension exhibit elevated levels of circulating IL-1β. Downregulation of the expression of key components of the NLRP3 inflammasome delays the development of hypertension and pharmacological inhibition of this inflammasome leads to reduced blood pressure in animal models and humans. Although the relationship between pyroptosis and hypertension is not well established yet, pyroptosis has been associated with renal and cardiovascular diseases, instances where high blood pressure is a critical risk factor. In this review, we summarize the recent literature addressing the role of pyroptosis and the inflammasome in the development of hypertension and discuss the potential use of approaches targeting this pathway as future anti-hypertensive strategies.
