Antitumor-specific autologous T cells express CCR4.

(A) Data represents T-cell lines (TCL) from 3 representative patients, of 5 tested. (B) Both CD4⁺ and CD8⁺ T cells express CCR4. Fluorescence intensity is shown on the x-axis. Blank areas represent fluorescence distribution of the molecules indicated and filled areas represent that of isotype-matched control antibodies. The cell number is shown on the y-axis.
