Boles, Winfried Barchet, Tom Diacovo, Marina Cella, and Marco Colonna From the Department of Pathology and Immunology, Washington University School of Medicine, St Louis, MO; and the Department of Pediatrics, Washington University School of Medicine, St Louis, MO. The tumor suppressor in lung cancer-1 (TSLC1) gene is frequently silenced in human lung carcinomas, and its expression suppresses tumorigenesis in nude mice. TSLC1 encodes a cell-surface protein called Necl-2 that belongs to the Nectin and Nectin-like (Necl) family of molecules. Necl-2 mediates epithelial cell junctions by homotypic contacts and/or heterotypic interactions with other Nectins and Necls. Thus, it inhibits tumorigenesis by ensuring that epithelial cells grow in organized layers. Here, we demonstrate that natural killer (NK) cells and CD8+ T cells recognize Necl-2 through a receptor known as class I-restricted T-cell–associated molecule (CRTAM), which is expressed only on activated cells. CRTAM–Necl-2 interactions promote cytotoxicity of NK cells and interferon (IFN-) secretion of CD8+ T cells in vitro as well as NK cell–mediated rejection of tumors expressing Necl-2 in vivo. These results provide evidence for an additional mechanism of tumor suppression mediated by TSLC1 that involves cytotoxic lymphocytes. Furthermore, they reveal Necl-2 as one of the molecular targets that allows the immunosurveillance network to distinguish tumor cells from normal cells.
