Gene therapy promising for growing tooth-supporting bone

.... This study mixed BMP-7 genes with an inactivated virus in a gel-like carrier and injected it into wounds. Giannobile said using a virus, with the harmful effects turned off, harnesses the virus' ability to enter into cells and use their genetic machinery. Once inside the cell, the viruses help BMP-7 gene...

Stopping smallpox in its tracks: A new anti-viral approach

...this approach "may serve to turn the tables on the virus by interfering with the very pathways that are required for viral replication and extrusion." This study demonstrates, for the first time, that chemical inhibition of host cell signaling pathways exploited by infectious agents represents a new avenue...
