Combinatorial suppression of IFN-γ signaling by T. gondii nuclear effectors.   The molecular dialogue between host and pathogen is defined by competition for the intracellular niche. Toxoplasma gondii exemplifies this mastery by deploying secreted effectors to remodel host cell biology and neutralize immune defenses. Yet a striking paradox has emerged, in which, despite exporting only …

  In both mice and humans, Type II interferon gamma (IFNγ) is crucial for the regulation of Toxoplasma gondii (T. gondii) infection, during acute or chronic phases. To thwart this defense, T. gondii secretes protein effectors hindering the host’s immune response. For example, T. gondii relies on the MYR translocon complex to deploy soluble dense …
