Prof Greenwood talks to ecancertv at Children with Cancer UK’s workshop on Drug Delivery in Paediatric Brain Tumours in London, UK.

He talks about the role of the blood-brain barrier (BBB) in protecting the brain and how it can be affected by disease such as brain tumours.

Prof Greenwood notes that the BBB is now increasingly considered to be part of a larger structure called the neurovascular unit, which incorporates other brain cells.
