T _reg cells express cytokine and chemokine receptors ex vivo. Expression of cytokine receptors on splenocytes isolated from Foxp3 GFP mice in which Foxp3 is expressed as a fusion protein with GFP. Grey curves indicate unstain controls. (a-d). Expression of indicated cytokine receptors on GFP^- (T_con) or GFP⁺ (T_reg) of splenocytes isolated ex vivo. (e-g). Expression of indicated or chemokine receptors of unstimulated T_reg cells (upper panels) or 3-day α-CD3 and α-CD28 stimulated T_reg cells (lower panels). Results are representative of two independent experiments.
