Adoptive transfer of CD25^- iTreg suppresses skin response in vivo. CD25^- iTreg from Co100 or Co66 immunized mice were adoptively transferred into FSA1-sensitized mice. The recipients were then challenged with flea antigens (skin test). Histamine and PBS were used as positive and negative controls for the skin test, respectively. *, p < 0.05, n = 3. Shown is one of three independent experiments with similar results.
