We investigated the effect of Treg skewing on the phenotypic and functional properties of CD4+CD127+CD25high cells, an activated subset of Teff, in 32 patients with AIH and 20 with AISC and in 36 healthy subjects. In AIH/AISC we noted a substantial increase in peripheral blood–derived CD4+CD127+ CD25high cells that display a Th1/Th17 phenotypic profile, as reflected by heightened interferon gamma and interleukin 17 (IL-17) production as well as by high levels of T-bet and related orphan receptor 3 expression, which is strongly correlated with disease activity. CD4+CD127+CD25high cells are unresponsive to low-dose IL-2 and in patients have marked proliferative ability, further enhanced by stimulation with IL-7. CD4+CD127+CD25high cells obtained from CD4+ cells exposed to Treg polarizing conditions display enhanced IL-10 production; up-regulate CD49b and LAG-3, markers of T regulatory 1 cells; and effectively suppress responder cell proliferation in both healthy subjects and AIH/AISC patients through a mechanism which is dependent on interferon gamma and IL-17. The suppressive function of CD4+CD127+CD25high cells is maintained upon proinflammatory challenge in healthy subjects but not in AIH/AISC. Conclusion: Treg skewing confers activated Teff phenotypic and functional properties of T regulatory 1 cells in health and in AIH/AISC, though suppressive function is lost in patients upon proinflammatory challenge; protracted modulation of the inflammatory environment is required to attenuate the effector potential while boosting immunoregulatory properties in Teff.
