Summary
Autophagy, a cellular process, can protect or harm brain cells during stroke. Therapeutic strategies must carefully balance its activation to achieve neuroprotection and improve stroke outcomes.
Area of Science:
- Cellular Biology
- Neuroscience
- Molecular Medicine
Background:
- Autophagy is a cellular process involved in maintaining homeostasis.
- Its role in ischemic stroke is complex, acting as both a neuroprotective and neurotoxic pathway.
- This duality presents challenges and opportunities for therapeutic intervention in stroke.
Purpose of the Study:
- To review mechanisms of autophagy in ischemic injury.
- To evaluate current and emerging therapeutic strategies targeting autophagy.
- To identify molecular targets for translational development in stroke medicine.
Main Methods:
- Narrative review of preclinical and clinical evidence.
- Synthesis of data on autophagy regulation in ischemic stroke.
- Analysis of molecular pathways and potential therapeutic targets.
Main Results:
- Moderate autophagy activation in early ischemia aids neuronal survival by clearing damaged components and reducing inflammation.
- Excessive or sustained autophagy, especially during reperfusion, can worsen injury and trigger cell death.
- A critical "Goldilocks zone" for autophagy activation is necessary for therapeutic benefit.
Conclusions:
- Therapeutic modulation of autophagy in stroke requires precise control of its activation levels.
- Clinical translation necessitates spatiotemporal precision and reliable biomarkers.
- Understanding genetic and sex-specific factors is crucial for precision stroke medicine.

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...
01:15Ischemic 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.
01:29Hemorrhagic 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...
01:29Stroke: Introduction and Types
A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
