Bone marrow macrophage (BMMF) response to IFNgR+FcgRI coincidence detection

ABSTRACT: Different cell types that make an organism use a small number of identical signaling modules to integrate external cues and elicit diverse functions. How the specificity of functional outcomes is achieved is unclear. It must lie within the context in which the external cue is perceived and integrated by the target cell. Within the innate immune system, we discovered communication between two classes of heterologous receptors designed to integrate external cues into context-specific response. Using IFNgR as an example, we describe the structural and functional collaboration between cytokine receptors and the ITAM signaling module, in this case the Fcg-chain at the plasma membrane of phagocytes. Receptor coupling allowed IFNg to modify FcgRI responses during IgG-mediated phagocytosis and to specify cell autonomous antimicrobial functions.
