The S100B Protein: A Multifaceted Pathogenic Factor More Than a Biomarker.

Area of Science:

• Neuroscience
• Biochemistry
• Immunology

Background:

• S100B is a calcium-binding protein primarily found in astrocytes.
• It serves as a biomarker for neural distress and is implicated as a Damage-Associated Molecular Pattern (DAMP) molecule.
• Altered S100B levels correlate with disease progression in various neurological disorders.

Purpose of the Study:

• To explore the role of S100B as a common pathogenic factor in neurological diseases.
• To investigate the link between S100B levels, neuroinflammation, and disease severity.
• To evaluate S100B's potential as a therapeutic target.

Main Methods:

• Review of existing literature on S100B in neurological disorders.
• Analysis of S100B levels and distribution in patient and experimental models.
• Correlation studies between S100B alterations and clinical/toxic parameters.

Main Results:

• S100B levels in nervous tissue are directly related to disease progression.
• In experimental models, S100B overexpression exacerbates symptoms, while inactivation ameliorates them.
• Altered S100B levels correlate with clinical and toxic parameters across diverse neurological conditions.

Conclusions:

• S100B protein is a potential common pathogenic factor in various neurological disorders.
• Its role in neuroinflammation may underlie shared pathological processes.
• Modulating S100B activity could offer a therapeutic strategy for neurological diseases.
