Inhibition of tumor growth by interleukin 10 gene transfer in B16(F10) melanoma cells.

Interleukin 10 (IL-10) is a potent immunosuppressive cytokine with an antitumor activity. The effect of IL-10 on tumor growth was tested in murine melanoma cells manipulated by gene transfer to secrete IL-10. In mice bearing B16(F10) tumors expressing IL-10 tumor growth was decreased depending on the amount of secreted IL-10.
