New model may help science overcome the brain's fortress-like barrier

"The brain is protected by the near-impermeable blood brain barrier, a fortress which protects the brain but which also prevents the treatment of brain diseases, including brain tumours.

Dr Zaynah Maherally and team at the University of Portsmouth have developed a model that mimics the blood brain barrier, paving the way for better, more efficient and reliable tests of drugs to treat brain diseases."

“In a person with a brain disease like a brain tumour, or other neurological conditions such as Parkinson’s disease, dementia or head injuries, the strikingly complex defence works against medics and scientists trying to deliver what could be life-saving or life-prolonging treatments.”
