London: In what could raise hopes of thousands of families, scientists have managed to halt a rare brain disease that kills boys by the time of adolescence through an experimental gene therapy. During the treatment, the team of doctors used a virus known as a lentivirus—a disabled form of HIV— to deliver working genes into two Spanish boys suffering from X-linked drenoleukodystrophy (ALD), a common form of brain disease that affects boys at an early age of six.
“This gives children with ALD and their families the hope of a future,” said Professor of Paediatrics at Paris Descartes University, who led the research.
