Riquelme, Denise; Alvarez, Alvaro; Leal, Nancy; Adasme, Tatiana; Espinoza, Italo; Valdés, Juan Antonio; Troncoso, Natalia; Hartel, Steffen; Segura Hidalgo, Jorge Antonio; Hidalgo Tapia, María Cecilia; Carrasco, M. Angélica (2011)Neuronal electrical activity increases intracellular Ca2+ concentration and generates reactive oxygen species. Here, we show that high frequency field stimulation of primary hippocampal neurons generated Ca 2+ signals with ...

Sphingomyelinase-induced domain shape relaxation driven by out-of-equilibrium changes of composition Fanani, Maria Laura; De Tullio, Luisina; Hartel, Steffen; Jara, Jorge; Maggio, Bruno (Biophysical Society, 2009)Sphingomyelinase (SMase)-induced ceramide (Cer)-enriched domains in a lipid monolayer are shown to result from an out-of-equilibrium situation. This is induced by a change of composition caused by the enzymatic production ...
