Inflammation and vascular tone pathways

Inflammation and vascular tone pathways represent a complex network of biochemical signaling processes that regulate the body's immune response and the diameter of blood vessels [1]. These pathways are highly integrated; for instance, pro-inflammatory cytokines can impair endothelial function, leading to altered vascular reactivity and hypertension [2]. Key molecular players within these pathways include the cyclooxygenase (COX) enzymes, nitric oxide synthase (NOS), and the renin-angiotensin-aldosterone system (RAAS) [3]. Pharmacological intervention in these pathways is a cornerstone of treating cardiovascular and inflammatory diseases, utilizing drugs such as NSAIDs, ACE inhibitors, and statins to restore homeostatic balance [4]. Because this term encompasses multiple distinct molecular targets rather than a single receptor or enzyme, it is classified as a biological process or pathway group rather than a single therapeutic target [5].
