Relationship between hyperuricemia, HSP70 and NLRP3 inflammasome in arterial hypertension.

Arterial hypertension is the most important cardiovascular risk factor in chronic non-communicable diseases and is estimated to be responsible for 10.4 million deaths annually. The global prevalence of hypertension is 30% and the majority of people with hypertension do not have a clear identifiable cause and are considered to have primary hypertension. Experimental and clinical investigations from several research groups, including ours, have established that inflammation and autoimmune reactivity play a role in the sodium retention and hemodynamic responses that drive primary hypertension. Hyperuricemia and heat stress proteins (HSP), particularly HSP70, are both associated with the activation of innate immunity that plays a role in the development of inflammatory reactivity in the hypertensive patient. Clinical studies have shown an association between the expression of HSP70 and anti-HSP70 antibodies and primary hypertension. This brief review aims to examine the interrelation between hyperuricemia and extracellular overexpression of HSP70 in the activation of the inflammasome that may have a central role in the pathophysiology of primary hypertension.
