The straightforward notion that tumor cells always exert immunosuppressive functions has been contradicted by the finding that myeloid leukemia cells can express potent co-stimulatory molecules. Indeed, the co-stimulatory support offered by leukemia cells can provoke helper T-cell responses. Unfavorably, this interaction allows leukemia cells to acquire immunosuppressive capacities.
