Spreading depolarization (SD) activates beneficial cell survival and plasticity pathways, not just damage. Gene expression analysis reveals compensatory mechanisms and potential therapeutic targets in brain tissue.
Area of Science:
- Neuroscience
- Molecular Biology
- Genomics
Background:
- Spreading depolarization (SD) is a wave of neuronal depolarization with known damaging effects.
- Potential beneficial roles of SD in activating cell survival and plasticity pathways remain unclear.
- Previous studies lacked unbiased assessment of compensatory mechanisms following SD.
Conclusions:
- SD can recruit compensatory and repair mechanisms, including pathways involved in cell survival and plasticity.
- Identified novel biological pathways and functional targets potentially involved in brain tissue recovery after SD.
- Results highlight the importance of appropriate controls and spatial considerations in SD research.
