Researchers may have unlocked the blood-brain barrier
The brain is composed of billions of neurons — vulnerable cells that require a protective environment to function properly. This delicate environment is protected by 400 miles of specialized vasculature designed to limit which substances come into contact with the brain. This blood-brain barrier is essential for protecting the organ from toxins and pathogens. But it also blocks the passage of therapeutic drugs.
