The Role of Excitotoxic Programmed Necrosis in Acute Brain Injury
Excitotoxicity involves the excessive release of glutamate from presynaptic nerve terminals and from reversal of astrocytic glutamate uptake, when there is excessive neuronal depolarization. N-methyl-d-aspartate (NMDA) receptors, a subtype of glutamate receptor, are activated in postsynaptic neurons, opening their receptor-operated cation channels to allow Ca(2 +) influx. The Ca(2 +) influx act...
متن کاملNeuronal injury and death following focal mild brain injury: The role of network excitability and seizure
Objective(s): While traumatic brain injury (TBI) is a predisposing factor for development of post-traumatic epilepsy (PTE), the occurrence of seizures following brain trauma can infuriate adverse consequences of brain injury. However, the effect of seizures in epileptogenesis after mild TBI cannot yet be accurately confirmed. This study was designed to investigate the ...
متن کاملThe Role of Caspase 9 during Programmed Cell Death in Ciliary Ganglia of Chick Embryos
During programmed cell death (PCD) apoptosis is controlled by many factors such as proteases. With no specific protease (s) known during PCD in the developing nervous system so far, we sought to determine if any specific protease (s) is involved in this process and therefore used different protease inhibitors during PCD (from embryonic day 6 to 10) in chick embryos. Among the inhibitors commerc...
متن کاملRole of programmed cell death in carcinogenesis.
Cells possess within their repertoire of genetic programs the ability not only to proliferate and be functionally active, but also to activate and undergo a process of self-induced destruction. This process, called programmed cell death, involves a genetic reprogramming of the cell that results in an energy-dependent cascade of biochemical and morphological changes within the cell that result i...
متن کاملMechanisms of programmed cell death in the developing brain.
Programmed cell death (apoptosis) is an important mechanism that determines the size and shape of the vertebrate nervous system. Recent gene-targeting studies have indicated that homologs of the cell-death pathway in the nematode Caenorhabditis elegans have analogous functions in apoptosis in the developing mammalian brain. However, epistatic genetic analysis has revealed that the apoptosis of ...
