Ceramide and mitochondria in ischemic brain injury
International Journal of Biochemistry and Molecular Biology
|December 22, 2011
Summary
Ceramides, crucial for cell signaling, accumulate in mitochondria during brain ischemia/reperfusion injury. This review explores their role in mitochondrial dysfunction and potential therapeutic targets for stroke.
Area of Science:
- Biochemistry
- Cell Biology
- Neuroscience
Background:
- Sphingolipids, like ceramides, are vital membrane components and signaling molecules.
- Mitochondria are increasingly recognized as key sites for sphingolipid metabolism.
- Mitochondrial dysfunction is central to brain tissue damage following ischemia/reperfusion (IR).
Purpose of the Study:
- To review the role of ceramides in mitochondrial dysfunction after cerebral IR.
- To explore the potential of targeting ceramide metabolism for stroke therapy.
Main Methods:
- Literature review of experimental evidence.
- Analysis of sphingolipid metabolism in the context of IR-induced mitochondrial damage.
Main Results:
- Emerging data suggest ceramide metabolism is deregulated in IR-damaged mitochondria.
- Ceramides may play a critical role in causing mitochondrial damage and dysfunction during cerebral IR.
Conclusions:
- Ceramides are implicated as key players in mitochondrial dysfunction following cerebral IR.
- Targeting ceramide metabolism presents a promising avenue for novel stroke therapeutics.

01:15Ischemic 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...
01:16Cellular Injury IV: Necrosis
Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...
01:21Cytotoxic Edema: Pathophysiology
Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous supply...
01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:25Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
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...
