Calcium (Ca) accumulation inside mitochondria represents a pleiotropic signal controlling a wide range of cellular functions, including key metabolic pathways and life/death decisions. This phenomenon has been first described in the 1960s, but the identity of the molecules controlling this process remained a mystery until just few years ago, when both mitochondrial Ca uptake and release systems were genetically dissected. This finally opened the possibility to develop genetic models to directly test the contribution of mitochondrial Ca homeostasis to cellular functions. Here we summarize our current understanding of the molecular machinery that controls mitochondrial Ca handling and critically evaluate the physiopathological role of mitochondrial Ca signaling, based on recent evidences obtained through in vitro and in vivo models.
