Blood/Brain Barrier

The blood-brain barrier is a crucial protective mechanism that regulates the passage of substances between the bloodstream and the brain. This selectively permeable barrier helps prevent harmful toxins and pathogens from entering the central nervous system while allowing essential nutrients to pass through. Researchers are actively studying ways to bypass the blood-brain barrier for more effective drug delivery, particularly in treating neurological disorders such as Alzheimer's and Parkinson's disease. Understanding how the blood-brain barrier functions is essential for developing new therapies that can safely and efficiently target brain-related conditions.
