Background: NKp46/NCR1

NKp46 (also known as natural cytotoxicity receptor 1, NCR1), is a ~46 kDa Type 1 transmembrane protein and a member of the immunoglobulin superfamily (1). NKp46 is highly conserved in mammals and can be characterized by two extracellular C2-type Ig-like domains followed by a stalk region (1). NKp46 is expressed by activated and resting natural killer (NK) cells, innate lymphoid cell (ILC) 1, and a small population of T lymphocytes (1). NKp46, along with NKp30 and NKp44, are activating receptors that have been collectively termed the natural cytotoxicity receptors (NCRs) (2). The NKp46 and NKp30 receptors play a major role in triggering some of the key lytic activities of NK cells (2). NKp46 is the only cytotoxicity receptor with a mouse orthologue, known as mNKp46 (2).

NKp46 plays a critical role in the NK-cell lysis of allogenic, autologous, and xenogeneic cells (3). Activation of NKp46 signaling is mediated via its association with immunoreceptor tyrosine-based activation motif (ITAM) bearing molecules CD3zeta and FcRgamma (3). Upon receptor-engagement NK-cell cytotoxic activity and cytokine release occurs (3). This NKp46 signaling can be blocked with anti-NKp46 monoclonal antibody mediated cross-linking which causes calcium release and interferon-gamma (IFN-gamma) and tumor necrosis factor-alpha (TNF-alpha) secretion (3). NKp46 recognizes multiple ligands presented on tumor cells or pathogens and infected cells including influenza virus hemagglutinin and the parainfluenza virus hemagglutinin neuraminidase (2). Additional ligands for the NKp46 receptor include heparan sulfate (HS) glycosaminoglycans (GAGs), hemagglutinin of human vaccina virus, and vimentin expressed on cells infected with Mycobacterium tuberculosis (3).

NKp46 and its NCR counterparts have shown to be successful targets for cancer immunotherapy. More specifically, human and mouse NKp46 has shown promise in virotherapy due to its ability to stimulate NK cell activation by binding to reovirus sigma1 protein in a sialic acid-dependent manner (3). Another approach for NKp46 in cancer immunotherapy is through the use of NCR based chimeric antigen receptors (CARs). In this therapy, NCR1 supplied human T cells with anti-tumor properties via cytokine secretion, upregulation of activation markers, improved expansion, and cytotoxicity in both mouse and in vitro models (3).
