Investigators will test a biopsy of the tumor to see if the tumor cells are EBV positive and to see if the subject is eligible for this study. Then they will take some blood from the donor, which is used to grow T cells. First they will grow a special type of cell called dendritic cells (or monocytes), which stimulates the T cells and add a specially produced human adenovirus that carries the LMP1 and LMP-2a genes into the dendritic cells(or monocytes). Addition of a gene to the cells is known as gene transfer. These dendritic cells (or monocytes) are then used to stimulate T cells. The stimulation trains the T cells to kill cells with LMP on their surface. Investigators will then make more LMP-specific CTLs by stimulating them with EBV infected cells (which we will make from the subject's blood or the donor's blood by infecting them with EBV in the laboratory). They also will put the adenovirus that carries the LMP1 and LMP2 genes into these EBV infected cells so that they increase the amount of LMP1 and LMP2, which these cells have.
