Disclosed are compounds useful for alteration of NR2F6 activity. In some embodiments of the invention compounds disclosed are utilized for stimulation of NR2F6 activity, alone, or in combination with PKC activation. In other embodiments, the invention teaches use of compounds for inhibition of NR2F6 activation. Stimulation of NR2F6 within the context of the invention is useful, intra alia, for induction of immune inhibition, or stimulation of cellular proliferation without significant induction of differentiation. Inhibition of NR2F6 is desired in situations where the practitioner of the invention seeks to augment immune response, or induce cellular differentiation. In another embodiment, inhibition of NR2F6 expression is desired in situations where inhibition of cancer or cancer stem cells is needed.
