Coxiella burnetii inhibits activation of host cell apoptosis through a mechanism that involves preventing cytochrome c release from mitochondria.
Coxiella burnetii is an obligate intracellular pathogen and the etiological agent of the human disease Q fever. C. burnetii infects mammalian cells and then remodels the membrane-bound compartment in which it resides into a unique lysosome-derived organelle that supports bacterial multiplication. To gain insight into the mechanisms by which C. burnetii is able to multiply intracellularly, we ex...
متن کاملCytochrome C-mediated apoptosis.
Apoptosis, or programmed cell death, is involved in development, elimination of damaged cells, and maintenance of cell homeostasis. Deregulation of apoptosis may cause diseases, such as cancers, immune diseases, and neurodegenerative disorders. Apoptosis is executed by a subfamily of cysteine proteases known as caspases. In mammalian cells, a major caspase activation pathway is the cytochrome c...
متن کاملCyclosporin A inhibits apoptosis of human endothelial cells by preventing release of cytochrome C from mitochondria.
BACKGROUND Several experimental and clinical studies suggest that cyclosporin A (CSA) treatment reduces transplant atherosclerosis. Because oxidized LDL (oxLDL) is believed to play a key role in the development of atherogenesis, causing injury to the endothelium, and has been shown to induce apoptosis of endothelial cells, we investigated whether CSA inhibits oxLDL-induced apoptosis. METHODS ...
متن کاملMT-21 is a synthetic apoptosis inducer that directly induces cytochrome c release from mitochondria.
We reported previously that a synthetic compound, MT-21, induced apoptosis by activating c-Jun-NH2-terminal kinase via the Krs/MST protein, which is activated by caspase-3 cleavage dependent on reactive oxygen species production. Here we examine the activation mechanism of caspase-3, an important cysteine aspartic protease, during MT-21-induced apoptosis. We found that MT-21 activated caspase-3...
متن کاملCeramide induces cytochrome c release from isolated mitochondria.
This chapter addresses the role of mitochondria in apoptosis. Emphasis is put on the recently observed influence of ceramides on mitochondrial functions. We report here that N-acetylsphingosine (C2-ceramide), N-hexanoylsphingosine (C6-ceramide) and, to a much lesser extent, C2-dihydroceramide, induce cytochrome c (cyt c) release from isolated rat liver mitochondria. Ceramide-induced cyt c relea...
