Genetic manipulation of cell death and neuroplasticity pathways in traumatic brain injury.

ABSTRACT: Traumatic brain injury (TBI) initiates a complex cascade of secondary neurodegenerative mechanisms contributing to cell dysfunction and necrotic and apoptotic cell death. The injured brain responds by activating endogenous reparative processes to counter the neurodegeneration or remodel the brain to enhance functional recovery. A vast array of genetically altered mice provide a unique opportunity to target single genes or proteins to better understand their role in cell death and endogenous repair after TBI. Among the earliest targets for transgenic and knockout studies in TBI have been programmed cell death mediators, such as the Bcl-2 family of proteins, caspases, and caspase-independent pathways. In addition, the role of cell cycle regulatory elements in the posttraumatic cell death pat
