Summary

Neuron-specific enolase (NSE) shows promise as a biomarker but faces challenges in clinical use due to measurement method limitations. Improved methodologies are needed to accurately assess NSE for central nervous system damage.

Area of Science:

Biochemistry
Neuroscience
Clinical Diagnostics

Background:

Neuron-specific enolase (NSE) has been studied extensively since 1965 for its significance.
Despite its promise, NSE has not achieved widespread clinical application, especially for acute cerebrovascular accidents.
Contradictory findings exist regarding serum NSE measurement utility in critically ill patients.

Purpose of the Study:

To analyze the research directions of NSE.
To identify reasons for contradictory conclusions on NSE's clinical utility.
To propose improvements in NSE evaluation methods.

Main Methods:

Literature review and analysis of existing studies on NSE.
Critical evaluation of the enzyme-linked immunosorbent assay (ELISA) for NSE measurement.
Discussion of methodological limitations and specificity concerns.

Main Results:

The enzyme-linked immunosorbent assay (ELISA) is identified as a key limitation.
ELISA cannot differentiate enolase heterodimers or assess enzymatic activity.
This methodological flaw hinders accurate NSE evaluation for central nervous system damage.

Conclusions:

The current methodological approach for evaluating NSE (γγ-enolase) as a biomarker requires significant improvement.
The specificity of research methods and the term "neuron-specific enolase" need re-evaluation.
Enhanced methodologies are crucial for realizing NSE's potential in clinical practice.
