The expression of HLA-DR, CD27, CD80, and CCR7 on γδT cells in patients with sepsis were significantly higher than that in cells from healthy individuals (HLA-DR: 51.61 ± 4.54% versus 41.09 ± 2.48%, P < 0.01; CD27: 47.23 ± 3.80% versus 2.04 ± 0.26%; P < 0.001; CD80: 32.39 ± 5.96,% versus 9.70 ± 2.53%, P < 0.001; CCR7: 33.02 ± 4.03% versus 14.37 ± 1.71%, P < 0.001) (Fig. 1). Here, CCR7 is linked to Sepsis.
