背景
Neuron-specific enolase (NSE) is known to be a cell specific isoenzyme of the glycolytic enzyme enolase. It is also known as
gamma-enolase or nolase 2 (ENO2). It has neurotrophic and neuroprotective properties on a broad spectrum of central nervous system (CNS) neurons. NSE is a highly specific marker for neurons and peripheral neuroendocrine cells. In clinical, NSE could be used as a biomarker for neuronal injury.
