The complexity of immunoregulation has focused attention on the CD4+ T “suppressor” regulatory cell (Treg), which helps maintain balance between immunity and tolerance. An immunoregulatory T cell population that upon activation amplifies cellular immune responses was described in murine models more than thirty years ago. However, no study has yet identified a naturally occurring T “inducer” cell type. Here, we report that the ectoenzyme CD39/NTPDase1 (ecto-nucleoside triphosphate diphosphohydrolase 1) helps to delineate a novel population of human “inducer” CD4+ T cells (TInd) that significantly increases the proliferation and cytokine production of responder T cells in a dose-dependent manner. Furthermore, this unique TInd cell subset produces a distinct repertoire of cytokines in comparison to the other CD4+ T cell subsets. We propose that this novel CD4+ T cell population counterbalances the suppressive activity of suppressor Treg cells in peripheral blood and serves as a calibrator of immunoregulation.
