Effect of acute stress on hippocampal glutamate levels and spectrin proteolysis in young and aged rats.

abstract：:Axonal degeneration is a key component of many neurodegenerative diseases. Injured axons undergo a program of self-destruction termed Wallerian degeneration that is an active, well-regulated process. The pathways leading to axon fragmentation are uncharacterized, but experiments with wld(s) mutant mice led to the disc...
