...ed todeliver genes into the body. The new findings tell us that the entry of AAV intothe cell is facilitated by surface receptor molecules called alpha V beta5-integrins. Without the presence of these integrins, the ability of AAV to"infect" the cell and deliver its genetic payload is diminished, say stud...AAAS Report Attributes Majority Of Killings In Guatemala To State
