Scientists have genetically engineered stem cells to develop into cells of the immune system known as cytotoxic T lymphocytes or killer T cells. These cells can detect HIV infected cells and destroy them. The HIV virus however, eventually overwhelms the immune system as there are not enough T cells to get rid of the virus entirely. The researchers in the study were able to produce T cells that specifically target cells containing HIV proteins in a living organism.

According to lead investigator Scott G. Kitchen, "We believe that this is the first step in developing a more aggressive approach in correcting the defects in the human T cell responses that allow HIV to persist in infected people." In studies with mice, the researchers demonstrated that the engineered stem cells were capable of not only developing into T cells, but also traveling to HIV infected tissues and organs in order to combat the virus.

(3) check this one out says:

Thanks , I’ve recently been searching for information about this subject for a long time and yours is the best I’ve came upon till now. But, what concerning the bottom line? Are you certain about the source?|What i don’t realize is in fact how you are no longer really a lot more neatly-preferred than you might be right now. You’re very intelligent.
