  • Patent number: 6228640
    Abstract: A method is described whereby a dendritic cell derived from the CD34 hematopoietic cell lineage is directed to become a super antigen presenting cell that has been pulsed with tumor cell RNA or RNA expression products. The protocol provides for programming the maturation of dendritic cells to become antigen presenting cells. The protocol further provides for isolating tumor cell RNA from biopsy material that has been prepared in pariffin block storage. The directed dendritic cell is provided with a plurality of tumor markers by using tumor RNA in toto or the poly A+RNA fraction. Once activated the dendritic cells are incubated with T4 and T8 lymphocytes to stimulate and sensitize the T lymphocytes which upon introduction either into a donor host or a nondonor recipient will provide immune response protection.
