Trojan Horse Virus Controls Hiv Infection
...VSV -- which nowlooks like an uninfected T cell -- tricks HIV-infected cells into fusing with itinstead. This enables VSV, which easily kills cells, to gain entry into the HIV-infected cell and destroyit. The modified VSV cannot infect normal cells because it lacks its normalsurface protein. Thus, it tar...Biological Clocks No Longer Found Only In The Brain
