| Research Abstract |
In order to investigate the mechanism of intracellular signal transduction towards necrosis, we measured the effects of cyclophilin D on the energy metabolism of mitochondria and the changes of mitochondria observed upon induction of necrosis. The changes were detected by imaging single mitochondria with optical microscopy. As a result, we succeeded in 1) detection of the effects of cyclophilin D on the pyruvate metabolism in cells, 2) detection of long-lasting mitochondrial permeability transition in cells, and 3) simultaneous imaging of mitochondrial permeability transition and mitochondrial swelling. These results provide important information on the mechanism of necrosis as programmed cell death.
