Purinergic signalling in the nervous system: an overview.

abstract：:The endoplasmic reticulum responds to stress by initiating a cascade of events known as the 'unfolded-protein response' (UPR). The accumulation of misfolded proteins in the leukodystrophy Pelizaeus-Merzbacher disease activates this stress response, resulting in apoptosis of oligodendrocytes. Although it remains uncert...

Theoretically, first-spike times could underlie such rapid responses, but direct evidence has been lacking. Such evidence has now been uncovered in the human...
