Successful Regulatory T Cell-Based Therapy Relies on Inhibition of T Cell Effector Function and Enrichment of FOXP3+ Cells in a Humanized Mouse Model of Skin Inflammation

Expanded human Treg maintain their suppressive capacity in vitro. (a) Schematic representation of the huPBL-SCID-huSkin allograft model with adoptive transfer of PBMC combined with or without Treg (1 : 1 ratio). (b) Flow cytometric analysis of Treg before and after expansion. Representative dot plot showing CD25 and FOXP3 expression of input cells and expanded human Treg, respectively. (c) Suppressive capacity of the ex vivo-expanded Treg was examined using an in vitro suppression assay. The graph shows the Treg : Tconv ratio (-axis) and percentage inhibition of Tconv proliferation (y-axis) as analysed by 3H-Thymidin incorporation. is shown, .
