Blood-Brain Barrier
Key Takeaways
- The blood-brain barrier (BBB) prevents circulating toxins and pathogens from reaching the brain.
- Tight junctions between the epithelial cells and specific transporters keep the brain isolated and protected.
- Certain genetic variants increase your risk of BBB dysfunction.
- Blood-brain barrier dysfunction can be part of the cause of Alzheimer’s, depression, and neurological disorders.
