Stem Cells Kill HIV

Researchers at the University of California, Los Angeles, made a stunning announcement Monday: Stem cells can be engineered to kill HIV.

The results, published Monday in the online journal PLoS ONE, demonstrate that human stem cells can be engineered into the equivalent of a genetic vaccine.

We have demonstrated in this proof-of-principle study that this type of approach can be used to engineer the human immune system, particularly the T-cell response, to specifically target HIV-infected cells," lead investigator Scott Kitchen, assistant professor of medicine in the division of hematology and oncology at the Devid Geffen School of Medicine at UCLA, said in a release.

These studies lay the foundation for further therapeutic development that involves restoring damaged or defective immune responses toward a variety of viruses that cause chronic disease or even different types of tumors.


*This is good news. However, take note that the T cell "killing" of HIV infected cells was only shown in vitro and not in the mouse. The mouse did not have HIV. Good news that we can engineer T cells from stem cells to specifically kill HIV infected cells, but we need to show that these engineered T cells kill virus infected cells in vivo in organism that actually has HIV.Still, this is good news. There is progress :)
