We will use this blood to grow T cells. We will first infect the peripheral blood mononuclear cells with a specially produced human virus adenovirus) that carries part of the CMV gene to the monocytes which will stimulate the T cells. This stimulation will train the T cells to kill cells with the pp65 from the CMV virus on their surface. If this approach is insufficient to stimulate T cells which will kill the pp65 from the CMV virus then we will grow a special type of cell called dendritic cells which will stimulate the T cells and we will put the specially produced human virus (adenovirus) that carries the parts of the CMV gene (called pp65) into the dendritic cells. These dendritic cells will then be treated with radiation so they cannot grow. They will then be used to stimulate T cells. This stimulation will train the T cells to kill cells with the pp65 from the CMV virus on their surface.
