What is the blood-brain barrier?
The blood-brain barrier is a selective barrier that protects the brain from harmful substances while allowing essential nutrients to pass through.
How does the co-culture model work?
The co-culture model combines rat brain microvascular endothelial cells and astrocytes to simulate the conditions of the blood-brain barrier.
What are ferritin nano-cages?
Ferritin nano-cages are nanoscale carriers that can encapsulate drugs and facilitate their delivery across biological barriers.
Why is drug delivery to the brain challenging?
The blood-brain barrier restricts the passage of many drugs, making it difficult to treat central nervous system disorders effectively.
What implications does this research have?
This research could lead to improved therapies for neurological disorders by enhancing drug delivery across the blood-brain barrier.
