To answer these questions, we generated mixed bone marrow chimeras with a 1:1 mix of WT (Ly5.1) and Ripk3−/− (Ly5.2) donor cells adoptively transferred into irradiated WT hosts, which would allow us to track whether any difference in MAIT cell responses were cell intrinsic, basally or during infection (Fig. 5A). The gene discussed is RIPK3; the disease is infection.
