These signals involve increases in [Ca^2＋] in compartments such as the cytoplasm, nucleus, and mitochondria, and can display multiple shapes ranging from sin- gle transients to repetitive Ca^2＋ oscillations. Generation and shaping of stimulus specific [Ca^2＋] signatures depends on Ca^2＋ influxes and effluxes occurring at both the plasma membrane （PM） and membranes of the different subcellular compartments.展开更多
