Expression of cytokine receptors on TRCs. Expression of cytokine receptors on sorted LN-TRCs was analyzed with antibodies against CD25, CD124, CD125, CD126, CD210, gp130, CD217, IL-17RB, IL-17RC, CD119, CD120a, and TGF-βR1 (solid lines) or fluorescence minus one (shaded with dotted lines). Data are representative of three independent experiments.
