Mitochondrial swelling is a hallmark of mitochondrial dysfunction, and is an indicator of the opening of the mitochondrial permeability transition pore. We introduce here a novel quantitative in situ single-cell assay of mitochondrial swelling based on standard wide-field or confocal fluorescence microscopy. This morphometric technique quantifies the(More)
Cyclophilin D (cypD)-deficient mice exhibit resistance to focal cerebral ischemia and to necrotic but not apoptotic stimuli. To address this disparity, we investigated isolated brain and in situ neuronal and astrocytic mitochondria from cypD-deficient and wild-type mice. Isolated mitochondria were challenged by high Ca(2+), and the effects of substrates and(More)
