S100B raises the alert in subarachnoid hemorrhage
Reviews in the Neurosciences
|July 22, 2016
Summary
The calcium-binding protein S100B plays a dual role in subarachnoid hemorrhage (SAH), acting as both a potential biomarker and a factor in brain injury. Understanding S100B
Area of Science:
- Neuroscience
- Biochemistry
Background:
- Subarachnoid hemorrhage (SAH) is a severe neurological condition with high mortality and morbidity, necessitating novel therapeutic strategies.
- The calcium-binding protein S100B is implicated in SAH pathogenesis and serves as a brain injury biomarker.
- S100B, primarily expressed in astrocytes, influences neuronal function through intracellular signaling or receptor interactions.
Purpose of the Study:
- To review the multifaceted roles of S100B in the context of subarachnoid hemorrhage.
- To elucidate the mechanisms by which S100B contributes to SAH-induced brain damage and vasospasm.
- To identify S100B as a potential therapeutic target for SAH.
Main Methods:
- Literature review of studies investigating S100B in subarachnoid hemorrhage.
- Analysis of S100B expression and function in the central nervous system post-SAH.
- Examination of S100B's involvement in oxidative stress and neuroinflammation.
Main Results:
- S100B concentration-dependently exhibits neuroprotective or neurotoxic effects in neurons.
- Blood levels of S100B may serve as a predictive biomarker for SAH progression and prognosis.
- S100B contributes to cerebral vasospasm and brain damage via oxidative stress and neuroinflammation.
Conclusions:
- S100B is a key player in SAH pathophysiology, influencing both neuronal fate and vascular complications.
- Further understanding of S100B mechanisms in SAH can guide the development of new treatments.
- Targeting S100B may offer a novel therapeutic avenue for managing subarachnoid hemorrhage.

01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
01:14Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
01:19Cerebral Edema l: Introduction
Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
