Dr. Bergantin received his academic education at EPM-UNIFESP (Brazil) and UAM (Spain): degree in biomedicine (2008), MSc (2010) and PhD (2014). His research involves cell signaling mediated by Ca2+ and cAMP, skeletal and smooth muscles, peripheral and central nervous systems. His research work solved the enigma of the paradoxical effects produced by L-type Ca2+ channel blockers (TOP 25 Hottest Articles - Biochemistry, Genetics and Molecular Biology - Cell Calcium - TOP 1 July to September 2013/ TOP 5 October to December 2013/ TOP 1 January to December 2013 full year/TOP 6 January to March 2014). Since 1975, several clinical and experimental studies have reported that acute and chronic administration of L-type Ca2+ channel blockers (CCB), such as nifedipine, produces reduction in arterial pressure associated with a paradoxical increase of sympathetic activity. Despite this sympathetic hyperactivity has been initially attributed to adjust reflex of arterial pressure, the cellular and molecular mechanisms involved in this apparent sympathomimetic effect of the L-type CCB remained unclear for decades.
