Involvement of extracellular regulated kinase and p38 kinase in hippocampal seizure tolerance.

abstract：:Calpain, an intracellular cysteine protease, has been widely reported to be involved in neuronal cell death. The purpose of this study is to investigate the role of calpain activation in axonal damage-induced retinal ganglion cell (RGC) death.
