Expression of NKG2D, PD-1, and CD44 before treatment and 90 days after treatment. Surface receptors NKG2D, PD-1, and CD44 on γδ T cells were stained with the monoclonal antibodies of mouse anti-human NKG2D, PD-1, and CD44, then analyzed by flow cytometry with a FACSCantoTM II. MFI mean fluorescence intensity. Data are shown as individual data points with Scatter dot plot (line at: mean with SD). Comparison within groups: **P < 0.01; ***P < 0.001; comparison between groups: #P < 0.05; ##P < 0.01. Two-tailed Student’s t test (n = 62)
