Summary
Ischaemic stroke causes death and disability due to impaired blood flow. Understanding apoptosis, a programmed cell death, offers new therapeutic strategies for stroke treatment.
Area of Science:
- Neuroscience
- Cell Biology
- Pathology
Context:
- Ischaemic stroke is a leading cause of death and disability globally.
- Focal impairment of cerebral blood flow initiates the stroke cascade.
- Cell death in stroke includes both necrosis and a therapeutically relevant delayed apoptosis.
Purpose:
- To summarize the neurological features of focal brain ischaemia.
- To detail the morphological signs of apoptotic and necrotic cell death.
- To elucidate the mechanisms of apoptosis in ischaemic stroke.
Summary:
- Apoptosis involves an early genetic decision phase and a cellular execution phase.
- Key events include shifts in apoptotic gene balance, calcium homeostasis disruption, and mitochondrial dysfunction.
- Caspases play a crucial role, with intrinsic, extrinsic, and caspase-independent pathways.
Impact:
- Understanding apoptosis mechanisms can lead to novel therapeutic approaches for ischaemic stroke.
- Identifying anti-apoptotic targets offers potential for neuroprotection.
- Experimental studies provide a basis for future clinical applications in stroke therapy.
