Mitochondrial Ca2+ waves
3D mitochondrial structure


The research activity focuses on the study of the mitochondrial calcium uniporter (MCU), the Ca2+ uptake pathway of mitochondria identified in 2011 by the group. The work includes the investigation of the structure/function relationship of MCU and its regulators, and of the role of MCU in the physiology and pathology of striated muscles, endocrine cells and neurons, both in cell cultures and in LoxP/CRE based transgenic mouse lines in which MCU is specifically ablated in a tissue.
