NKT cells are key mediators of antiviral and anticancer immunity. Experiments in mice have demonstrated that activation of NKT cells in vivo induces the expression of multiple effector molecules critical to successful immunity. Human clinical trials have shown similar responses, although in vivo activation of NKT cells in humans or primate models are far more limited in number and scope. Measuring ex vivo activation of NKT cells by the CD1d-restricted glycolipid ligand α-Galactosylceramide (α-GalCer) through cytokine expression profiles is a useful marker of NKT cell function, but for reasons that are unclear, this approach does not appear to work as well in humans and non-human primate maca..View full abstract
