'Silencing' HIV with small bits of RNA

Researchers have shown that they can effectively tackle HIV-1 with small bits of gene-silencing RNA by delivering them directly to infected T cells, the major targets of the virus. While earlier studies had shown such a strategy could fight against many viruses including HIV-1, the new study in mice with human blood cells, so-called humanized mice, is the first to demonstrate an effective approach to systemic delivery in a living animal.
