Fig 6. Expression of CD52, CD244 and CD161 protein on the cell surface of CD3^-CD56^dim NK and CD3⁺ T cells isolated from relapsed ADAMTS13-deficient TTP patients in remission.

Mean fluorescence intensity (MFI) of CD52, CD244 and CD161 on CD3^-CD56^dim and CD3^-CD56^bright NK cells (A) and on CD3⁺ T cells (B) derived from relapsed (R) or non-relapsed (NR) TTP patients. Representative histograms of fluorescence intensity of markers exhibiting significant differences between relapse (thick, dashed lines) and non-relapsed (thin, solid lines) patients are shown in C. (relapse n = 9, non-relapse n = 13, Mann-Whitney test; **p<0.01).
