Abstract

The findings summarized here provide a direct comparison of the immunogenicity of various DC loading strategies included pulsing with protein, peptide, tumor cell lysate, irradiated tumor cells and electrofusion of DCs and tumor cells. For the treatment of 3-day established pulmonary metastases, electrofusion of DCs and tumor cells generated a therapeutic vaccine far superior to other methods of DC loading. Consistent with their therapeutic activity, fusion hybrids stimulated the release of the largest amount of interferon-gamma from immune T cells. However, IL-10 secretion did not correlate with in vivo therapeutic reactivity. In conclusion, DC-tumor fusion hybrids were the most effective vaccine to eradicate existing tumors. These data support the use of DC-tumor electrofusion cells for the treatment of human cancer.
