New Method Delivers Alzheimer’s Drug to the Brain

(Science Daily) Oxford University scientists have developed a new method for delivering complex drugs directly to the brain, a necessary step for treating diseases like Alzheimer's, Parkinson's, Motor Neuron Disease and Muscular Dystrophy…
The team has successfully switched off a gene implicated in Alzheimer's disease in the brains of mice by exploiting exosomes -- tiny particles naturally released by cells. The exosomes, injected into the blood, are able to ferry a drug across the normally impermeable blood-brain barrier to the brain where it is needed.
Although this is a significant and promising result, there are a number of steps to be taken before this new form of drug delivery can be tested in humans in the clinic.
