Central nervous system circuitry and peripheral neural sympathetic activity responsible for essential hypertension.

Full Abstract

Both clinical and experimental studies dealing with patients affected by idiopathic or essential hypertension (EH) are devoted to the great deal of physiological, pharmacological and pathological as well as therapeutical issues of EH. However, most articles devoted to EH do not refer to the central nervous system mechanisms underlying this disease and the channels which allow that these mechanisms are funneled to the peripheral autonomic nervous system and trigger this cardiovascular disorder. In the present review article we attempted to reach this target devoted to the central nervous system circuitry involved in the cardiovascular pathophysiology. We postulated that EH depends on the predominance of the binomial A5 noradrenergic (NA) nucleus + median raphe serotonergic (5-HT) nucleus over the (A6)-NA + dorsal raphe-5HT nuclei. This hypothesis receives additional support from our results obtained throughout the neuropharmacological therapy of this type of neurophysiological disorder. Our therapeutical strategy is addressed to enhance the activity of the (A6)-NA + dorsal raphe-5HT binomial circuitry.
