CCR4 and CTACK-dependent reduction of ear swelling in a cutaneous DTH reaction. Thy1.1 congenic recipients were treated with anti-CTACK mAb or the isotype control before the adoptive transfer of immunized Thy1.2+ donor LN cells. Recipient or control mouse ears were stimulated by local application of DNFB. Swelling induced by transferred CCR4−/− but not by wild-type immune T cells is blocked with a mAb against CTACK. Background swelling of DNFB treated recipients without donor cells has been subtracted (mean ± SEM of seven experiments).
