Figure Lengend Snippet: One-month nivolumab- CD3 + and KIR2DL2/DL3+ NKs predict response. A, Frequencies of CD3 + , CD4 + , NKs and KIR2DL2/DL3+ NKs, and ICOS+ Tregs in R vs. NR patients. CD3 + T cells: 33 R vs. 22 NR, P < 0.05; CD4 + T cells: 33 R vs. 22 NR, P < 0.05; NKs: 31 R vs. 21 NR, P < 0.05; KIR2DL2/DL3+ NKs: 30 R vs. 21 NR, P < 0.05; ICOS+ Tregs: 23 R vs. 19 NR, P < 0.05. Two-tailed test comparison of differences between two independent groups ( P < 0.05). Box plot showing the data distribution across groups with minimum, median, and maximum values. Two-tailed test comparison of differences between two independent groups (*, P < 0.05; **, P < 0.01; ***, P < 0.001). B, Kaplan–Meier survival curves for PFS and OS of patients with mRCC-REV stratified according to optimal cutoff identified by ROC analyses. C, Kaplan–Meier plots showing PFS and OS of patients stratified according to a combination of CD3 + - KIR2DL2/DL3+ NKs. High–Low (black line); High–High (red line); Low–High (blue line); Low–Low (light blue line). P -values by long-rank test.
Article Snippet: PB-derived CD4 + CD25 + Tregs and PB-derived CD4 + CD25 − T effector cells (Teffs) were isolated from fresh PBMCs using the Dynabeads Regulatory CD4 + CD25 + T-cell kit (>95% purity tested by flow cytometry; Invitrogen by Life Technologies, Cat. #11363D).
