Blood-brain barrier breached by new therapeutic strategy

...siRNA bound to the rabies peptide through the tail veins in one group of mice, while other mice served as control groups. All the mice in the control groups died from JEV infection; in contrast, 80 percent of the mice that got the antiviral siRNA linked to the rabies peptide survived. These experiments dem...
