To generate longlasting memory T cells and to allow repetitive stimulation of cytotoxic T cells, dendritic cells have to interact with both, activated CD4+ helper T cells and CD8+ T cells. In these scenarios, cytotoxic lymphocytes (CL), mainly cytotoxic T cells (Tc) and natural killer (NK) cells, are ultimately responsible for killing the cancer cells and eradicating the tumor. C) cytotoxic hypersensitivity Bone marrow takeover: Lymphomas and other cancers which spread to the bone marrow crowd out healthy stem cells in the bone marrow (precursors of T-cells) resulting in the depletion of T-cells.
