Interleukin (IL)-15, a pleiotropic cytokine, is involved in the development and maintenance of NK cells and memory CD8+ T cells. We examined the effects of in vivo overexpression of IL-15 on protection against 2 types of murine B16 melanoma lines, MHC class I-negative B16.44 and MHC class I-positive B16F10 cells, using IL-15 transgenic (Tg) mice that we have recently constructed. The tumor growth was severely retarded in IL-15 Tg mice after subcutaneous (s.c.) inoculation with B16.44 or B16F10 cells. IL-15 Tg mice showed an augmented NK cell activity against B16.44 cells, and in vivo depletion of NK cells by anti-asialoGM1 Ab treatment abrogated the antitumor activity in IL-15 Tg mice. On the other hand, IL-15 Tg mice inoculated with B16F10 cells developed a significant level of CTL response against B16F10 cells, and in vivo depletion of CD8+ T cells by anti-CD8 MAb treatment abrogated the antitumor activity. Thus, overexpression of IL-15 augmented antitumor activity against different tumors via augmentation of different antitumor mechanisms. These results suggest a possible therapeutic application of IL-15 for human neoplasms expressing a wide range of MHC class molecules.
