Scientists from the University of Oxford have developed a new way of delivering drugs to the brain.

An experiment was conducted on mice in which exosomes that are the body's own transporters were used to deliver drugs.

It was added by the authors that various diseases like Parkinson's, Alzheimer's and Muscular Dystrophy can be treated with the study, in Nature Biotechnology.

The Alzheimer's Society further added that these findings could pave way for better treatments as the study was exciting.

When it comes to getting any treatment for diseases of the brain, a major challenge is making a treatment crossing the blood-brain barrier.

The brain is protected by the barrier that exists and this does not let the bacteria cross over from the blood while letting oxygen through.

There are chances of the drugs getting blocked and due to this there are problems for medicine. The barrier was made to cross using exosomes in this study.

Materials are transported between cells by using exosomes that act like the body's own fleet of incredibly small vans.

Mice were injected with siRNA, which is a piece of genetic code that was filled with exosomes.

The gene called BACE1 was turned off after siRNA was delivered to the brain cells and Alzheimer's disease is caused with this gene.

There was a 60 per cent reduction in the activity of genes following this.

Lead researcher Dr Matthew Wood said, "These are dramatic and exciting results."
