Hypertension is a major risk factor for cardiovascular disease, which is a serious health problem in the highly industrialized countries. In more than 95% of the cases, the etiology of hypertension remains unknown. a key role in the etiology of hypertension is played by endothelial dysfunction and the inflammatory reaction in the vascular wall, in which the low molecular weight proteins -so-called chemokines -are involved. The chemokines involved in the pathogenesis of hypertension include monocyte chemoattractant protein-1, MCP-1, CCL2, interferon--inducible protein (IP-10; CXCL10), interleukin-8 (IL-8; CXCL8), RaNTeS (CCL5), fractalkine (CX3CL1) and their receptors CCR2, CCR5, CXCR1, CXCR2, CXCR3 and CX3CR1. The mechanisms involving chemokines and their receptors in the pathogenesis of hypertension are complex and not fully understood. They include the impact of the migration of macrophages and monocytes to the vascular wall, endothelial dysfunction, effects on nitric oxide and endothelin-1 and smooth muscle cell proliferation. Chemokines are also involved in the pathogenesis of complications of hypertension, such as atherosclerosis, myocardial and renal fibrosis. Hypertension is one of the most important risk factors for cardiovascular diseases. In Poland, cardiovascular diseases pose a major medical, economic and social problem. The prevalence of hypertension in Poland reaches 32% of the adult population, but only one in three Poles suffering from hypertension is aware of the disease [1]. In more than 95% of the cases, the etiology of essential hypertension remains unknown. a significant role in the pathogenesis of hypertension is played by genetic factors regulating the transport of ions and water, renal hemodynamics and the function of numerous hormones such as aldosterone, catecholamines, renin, vasopressin and endothelin-1 (eT-1). The level of blood pressure depends on the interplay of numerous systems and factors such as the renin-angiotensin-aldosterone system (RaaS), the sympathetic nervous system, natriuretic peptides and the vascular endothelium. blood pressure level is also affected by factors such as sodium intake, low physical activity, stress and obesity. In recent years, attention has been paid to the participation of inflammatory factors in the etiology of hypertension leading to endothelial dysfunction, which in turn plays a key role in the pathogenesis of hypertension. Low molecular weight proteins of the cytokine family which have the ability to stimulate and control leukocyte migration -so-called chemokines -participate in the inflammatory reaction involving the vascular wall. These proteins have the ability to bind to receptors associated with 7-transdomain G proteins; however, most chemokines bind to more than one receptor, and the receptors are capable of binding more than one * dorian Nowacki's doctoral scholarship is co-financed by the european Union as part of the european Social fund.
