Engineered cells seek out and kill HIV in living organisms

Although there is currently no cure for HIV, the body does already contain cells that fight the virus – the problem is, there just aren’t enough of them to completely get rid of it. In 2009, scientists at UCLA performed a proof-of-concept experiment, in which they were able to grow these CD8 cytotoxic T lymphocytes (better known as infection-fighting “T cells”) from genetically engineered human stem cells. Now, in a subsequent study, they have demonstrated that these engineered cells can seek out and kill HIV-infected cells in a living organism.
