Based on literature, IL-23 mediate IL-17 release in Th17 cells. Is it possible to induce IFN-g in human T cells? Does it require a secondary co-priming cytokine?
If you are asking about in vitro conditions to find the detectable levels of this, Yes IFN-Y can be induced by stimulating T cells with PMA and Inomycin in presence of BFA.
