To check whether iNKT-derived IFN-γ suppresses Tregs, which would prevent the immunosuppression during post-phase of sepsis, the sepsis-survived mice (14 days of CLP) that are administrated with vehicle or α-Galcer or α-Galcer/IFN-γAb were rechallenged with Listeria monocytogenes (Lm). Here, IFNG is linked to Sepsis.
