Objective
NK cells that are well known by their ability to recognize and eliminate virus infected and tumor cells were also implicated in the defence against bacteria. However, the recognition of bacteria by NK cells is only poorly understood. we do not know how bacteria are recognized and the functional consequences of such recognition are also weakly understood. In the current proposal we aimed at determining the “NK cell receptor-bacterial interactome”. We will examine the hypothesis that NK inhibitory and activating receptors are directly involved in bacterial recognition. This ground breaking hypothesis is based on our preliminary results in which we show that several NK cell receptors directly recognize various bacterial strains as well as on a few other publications. We will generate various mice knockouts for NCR1 (a major NK killer receptor) and determine their microbiota to understand the physiological function of NCR1 and whether certain bacterial strains affects its activity. We will use different human and mouse NK killer and inhibitory receptors fused to IgG1 to pull-down bacteria from saliva and fecal samples and then use 16S rRNA analysis and next generation sequencing to determine the nature of the bacteria species isolated. We will identify the bacterial ligands that are recognized by the relevant NK cell receptors, using bacterial random transposon insertion mutagenesis approach. We will end this research with functional assays. In the wake of the emerging threat of bacterial drug resistance and the involvement of bacteria in the pathogenesis of many different chronic diseases and in shaping the immune response, the completion of this study will open a new field of research; the direct recognition of bacteria by NK cell receptors.
