ABSTRACT
In the cardiovascular field, tachycardia and increment of catecholamine plasma levels (sympathetic hyperactivity) have been reported by hypertensive patients that use L-type Ca2+ channel blockers (CCBs) since 70´s. Our discovery of the involvement of interaction between the intracellular signalling pathways mediated by Ca2+ and cAMP (Ca2+/cAMP interaction) revealed that this phenomenon (sympathetic hyperactivity) was resulting of increase of transmitter release from sympathetic neurons stimulated by CCBs due to its interference on the Ca2+/cAMP interaction. In the neuroscience field, this discovery has produced new paths for the understanding of the cellular and molecular mechanisms involved in the pathogenesis of neurodegenerative diseases, such as Alzheimer´s and Parkinson’s diseases. In this way, novel journeys for the development of new pharmacological strategies more effective for the treatment of neurodegenerative diseases may be initiated.
