| 内容記述 | Double-stranded （ds）RNA-recognition receptors reside in the cytoplasm and membranes of cells. These receptors are implicated in the differential screening of microbes by the host. Myeloid dendritic cells （mDCs） recognize and respond to polyI:C, an analog of dsRNA, by endosomal TLR3 and cytoplasmic MDA5. NK cells are induced in vivo by the administration of polyI:C to mice and in vitro are reciprocally activated by mDCs, although the molecular mechanisms as yet undetermined. Here, we show that the TLR adapter TICAM-1 （TRIF） participates in mDC-derived antitumor NK activation. In a syngeneic mouse tumor implant model, intraperitoneal administration of polyI:C led to the retardation of tumor growth, which eff ect relied largely on NK activation. This NK-dependent tumor regression did not occur in TICAM-1-/- or IFNAR-/- mice, while a normal NK antitumor response was induced in PKR-/-, MyD88-/-, IFN-β-/- and wild-type mice. IFNAR was a prerequisite for the induction of IFN-α/β and TLR3. The lack of TICAM-1 did not aff ect IFN production but resulted in unresponsiveness to IL-12 production, mDC maturation and polyI:C-mediated antitumor activity. This NK activation required NK-mDC contact in in vitro transwell analysis. NKantitumor activity was successfully introduced into tumor-implanted mice by transferring mDCs expressing TICAM-1. Implanted tumor growth in IFNAR-/- mice was retarded by adoptively transferring polyI:C-treated TICACM-1-positive mDCs but not TICAM-1-/- mDCs. Thus, TICAM-1 rather than MDA5 in mDCs critically facilitated mDC-NK contact and activation of antitumor NK, resulting in the regression of low MHC-expressing tumors |
