Delivering Genes Across the Blood-Brain Barrier

Caltech biologists have modified a harmless virus in such a way that it can successfully enter the adult mouse brain through the bloodstream and deliver genes to cells of the nervous system. The virus could help researchers map the intricacies of the brain and holds promise for the delivery of novel therapeutics to address diseases such as Alzheimer’s and Huntington’s. In addition, the screening approach the researchers developed to identify the virus could be used to make additional vectors capable of targeting cells in other organs. - See more at:”
