Targeting The Mitochondrial Permeability Transition Pore In Traumatic Central Nervous System Injury, Joe E. Springer, Pareshkumar Prajapati, Patrick G. Sullivan

Spinal Cord and Brain Injury Research Center Faculty Publications

The mitochondrion serves many functions in the central nervous system (CNS) and other organs beyond the well-recognized role of adenosine triphosphate (ATP) production. This includes calcium-dependent cell signaling, regulation of gene expression, synthesis and release of cytotoxic reactive oxygen species, and the release of cytochrome c and other apoptotic cell death factors. Traumatic injury to the CNS results in a rapid and, in some cases, sustained loss of mitochondrial function. One consequence of compromised mitochondrial function is induction of the mitochondrial permeability transition (mPT) state due to formation of the cyclosporine A sensitive permeability transition pore (mPTP). In this mini-review, …
