BACKGROUND: CD4+ CD25+ regulatory T (Treg) cells are involved in the downmodulation
of numerous immune responses to pathogens, tumors, or allergens. OBJECTIVE: In this
study, we further characterized the nature of Treg cells that control skin inflammatory
reactions to haptens. METHODS: In a model of contact hypersensitivity to 2, 4-dinitro-
fluorobenzene, we have investigated the phenotype, the specificity, and the origin of Treg
cells that modulate the priming of effector CD8+ T cells responsible for the development of …
