Abstract

Insights

Mitogen-activated protein kinases (MAPKs) play a key role in cerebral vasospasm after subarachnoid hemorrhage. Inhibiting MAPKs effectively prevents vasospasm, highlighting their therapeutic potential.

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Pharmacology

Background:

  • Mitogen-activated protein kinases (MAPKs) are implicated in cerebral vasospasm following subarachnoid hemorrhage.
  • Understanding MAPK pathways is crucial for addressing post-hemorrhage complications.

Purpose of the Study:

  • To review and synthesize current research on the role of MAPKs in cerebral vasospasm.
  • To identify knowledge gaps and suggest future research directions.

Main Methods:

  • Comprehensive literature search of PubMed and NIH databases (August 2009).
  • Keywords: subarachnoid hemorrhage, mitogen-activated protein kinases (MAPKs).
  • Inclusion of in vitro and in vivo studies.

Main Results:

  • MAPK inhibition, using specific inhibitors, demonstrated a preventative effect on vasospasm in most studies.
  • MAPK cascades appear to be a central signaling pathway in cerebral vasospasm.
  • The precise mechanism of MAPK-induced sustained vascular smooth muscle contraction requires further elucidation.
  • The role of endogenous MAPK inhibitors (MAPK phosphatases) in this context remains unexplored.

Conclusions:

  • Experimental evidence strongly supports a causative role for MAPKs in cerebral vasospasm.
  • Further investigation into MAPK signaling and its modulation is warranted for therapeutic development.

Hemorrhagic 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...
Cerebral Edema ll: Pathophysiology01:22

Cerebral 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...
Vascular Spasm01:16

Vascular Spasm

The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last for...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic 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...
Ischemic Stroke ll: Pathophysiology01:15

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
