Trojan Horse Virus Controls Hiv Infection

A team of researchers has developed a virus that controls HIV infection by targeting infected T cells. The modified virus, VSV, tricks infected cells into fusing with it instead of normal cells, allowing it to destroy the virus. This approach could lead to new treatments for HIV and other diseases.
