STANFORD – At Stanford University in California, new HIV resistant T-cells have been created that could prevent the development of AIDS (acquired immune deficiency syndrome).

The HIV virus attacks human T-cells, slowly destroying the entire immune system. Scientists at Stanford have developed a ‘molecular scissor’ that allows them to ‘glue’ HIV resistant genes into the T-cells, thereby making them stronger and resistant to breakdown.
The researchers are careful with saying that their discovery is not a cure fore AIDS but a method to make HIV positive patients immune to developing AIDS.
“Once a patient is HIV positive, they contract an array of infections and cancers which will eventually kill them, not the virus itself,” says Dr Matthew Porteus, member of the research team. “Our goal is to build up an immune system that is resistant to the virus.”
The newly discovered method works by replacing a percentage of the infected T-cells with the HIV-resistant variant, causing the bad cells to die off.
At the same time the resistant T-cells multiply until they have created a complete new and HIV resistant immune system.
“The virus simply would not have any more cells available to infect,” one researcher said.
The team of researchers is hoping to test their new HIV resistant T-cells on human patients within the next five years.
