Abstract
A lymphocyte subpopulation, the V α 14 natural killer T (NKT) cells, expresses both NK1.1 and a single invariant T cell receptor encoded by the V α 14 and J α 281 gene segments. Mice with a deletion of the J α 281 gene segment were found to exclusively lack this subpopulation. The V α 14 NKT cell–deficient mice could no longer mediate the interleukin-12 (IL-12)–induced rejection of tumors. Although the antitumor effect of IL-12 was thought to be mediated through natural killer cells and T cells, V α 14 NKT cells were found to be an essential target of IL-12, and they mediated their cytotoxicity by an NK-like effector mechanism after activation with IL-12.

- For measurement of the melanoma antigen (GM3 ganglioside) cells or tissues were homogenated. The homogenates of normal or metastatic livers (50 mg) or B16 melanoma were treated with 1 ml of extraction buffer containing 1% NP-40. Varied concentrations of melanoma cell homogenates were used to determine standard curves. Melanoma antigens in the extracts were quantified by radioimmunoassay with 125 I-labeled M2590 mAb to melanoma as described [

(1987) - Cells (1 × 10 6 ) were first incubated with mAb to Fc γ receptors II and III (FcγRII/III) (2.4G2) to block nonspecific staining through FcγR then the cells were incubated with fluorescein isothiocyanate–labeled anti-TCRβ (H57-597) and phycoerythrin–labeled anti-NK1.1 (PK136). Dead cells were excluded by propidium iodide staining and 10 5 cells were analyzed by EPICS-ELITE (Coulter Electronics Hialeah FL) with a logarithmic amplifier as described (5).
- J α 281 +/+ J α 281 –/– and RAG –/– V α 14 tg V β 8.2 tg mice were injected with 2 × 10 6 B16 or FBL-3 cells in the spleen for liver metastasis intravenously with 3 × 10 5 B16 or 2 × 10 6 LLC cells for pulmonary metastases or subcutaneously with 2 × 10 6 B16 cells for subcutaneous tumor growth on day 0. Recombinant murine IL-12 (2400 U/mouse) or phosphate-buffered saline (PBS) was injected on days 3 5 7 and 9. On day 14 the mice were killed and either metastatic nodules counted or GM3 melanoma antigens measured by radioimmunoassay in the liver or lung as described (22). For subcutaneous tumor growth injection of IL-12 or PBS was initiated on day 5 and the mice were treated five times per week. The diameters of tumors were measured every day with calipers. The sizes of tumors were expressed as the products of the longest diameter times the shortest diameter (in square millimeters).
- Target cells were labeled with 100 μCi of sodium chloride (Amersham) per 5 × 10 6 cells for 1 hour. Effector cells were seeded in 96-well round-bottomed plates at indicated effector/target (E/T) ratios against 1 × 10 4 target cells. The release of 51 Cr from lysed target cells was counted on a γ-counter after a 4-hour incubation at 37°C in 5% CO 2 . The percent of specific 51 Cr-release was calculated by the following formula: percent of specific lysis = (sample cpm – spontaneous cpm) × 100/(maximum cpm – spontaneous cpm). Spontaneous cpm was calculated from the supernatant of the target cells alone and the maximum release was obtained by adding 1N HCl to target cells.
- MAbs to H-2K b (AF6-885) H-2D b (KH-95) CD1d (1B1) V β 8 (MR5-2) NK1.1 (PK136) Ly49C (5E6) IFN-γ (R4-6A2) Fas (Jo2) and Fas ligand (K10) (Pharmingen) were used for blocking experiments.
