Genetically engineered T cells render HIV's harpoon powerless

When HIV attacks a T cell, it attaches itself to the cell's surface and launches a "harpoon" to create an opening to enter and infect the cells. To stop the invasion, researchers have developed genetically engineered T cells armed with a so-called "fusion inhibitor" to disrupt this critical step and prevent a wide range of HIV viruses from entering and infecting the T cells.
