Researchers from Indiana have found a possible way to better deliver cancer drugs to tumors in the brain. The challenge in delivery lies in what’s called the blood-brain barrier.

The blood-brain barrier protects the brain from dangerous foreign substances but also blocks drugs including chemotherapy from reaching tumors that have spread to the brain.

Purdue University scientists have provided the first comprehensive look at the blood-brain and blood-tumor barriers.
