ABSTRACT
The International Symposium on Chromaffin Cell Biology (ISCCB) brings together a group of approximately 150 scientists from around the world who meet every 2 years to discuss recent advances in our understanding of biogenesis and motion of secretory vesicles, synthesis, storage and release of secreted products (catecholamines, chromogranins, ATP), and mechanisms involving the excitation-secretion coupling, membrane ion channels, intracellular calcium homeostasis and exocytosis. The development of new technologies that allow an accurate measurement of catecholamines, vesicle motion, exocytosis, etc. are also analyzed. The 12th ISCCB, organized by Ricardo Borges, took place on September 20-26, 2003, in La Palma, Canary Islands, Spain. In this article we describe the most recent and significant contributions to the 12th ISCCB.
