Background

S100B is a zinc- and calcium-binding protein belonging to the S100 protein family within the EF-hand (helix E-loop-helix F) subgroup (1,2). S100B plays a role in normal central nervous system development, is associated with various neurological diseases such as Alzheimer's and Parkinson's, and it serves as a marker for brain injury (1,2). The S100B protein has a homodimeric structure comprised of two 91-amino acid polypeptide monomers each with a theoretical molecular weight of 10.5 kDa (1,2). Furthermore, each monomer contains two EF-hand regions, four helixes, and a hinge region (2). S100B is predominately expressed in astrocytes, oligodendrocytes, and Schwann cells, but also other cell types including adipocytes (1,3). S100B interacts with toll-like receptor 4 (TLR4) and receptor for advanced glycation end products (RAGE), initiating downstream signaling cascades and transcription factors including JNK/JUN, NFkappaB, and p38, leading to caspase and proinflammatory cytokine production (2). Overall outcomes include neuronal apoptosis, neuroinflammation, and neurodegeneration (1,2). S100B is the most commonly studied astroglia and blood brain barrier biomarker in traumatic brain injury (TBI) (3,4). The serum levels of S100B in patients with TBI is indicative of patient outcomes, where high levels correlate with injury severity and mortality (4). S100B is often in used in combination with additional biomarkers such as glial fibrillary acidic protein (GFAP) and ubiquitin c-terminal hydrolase L1 (UCH-L1) (3,4).
