What Researchers Did
Researchers investigated how hyperbaric oxygen affects brain cells and whether activating a cell clean-up process called mitophagy could protect them from damage.
What They Found
They found that hyperbaric oxygen (HBO) at 6 ATA with 100% oxygen damaged mitochondria and reduced their energy potential in brain cells, unlike hyperbaric normoxia. While the cells started a clean-up process called mitophagy, it was too slow to remove damaged mitochondria effectively. However, when mitophagy was pre-activated using everolimus, it promptly cleared dysfunctional mitochondria, prolonged seizure latency, and protected against cell death.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
A limitation of this study is that its findings are based on animal models and cell cultures, which may not directly translate to human physiology.
