CD39 is up-regulated on tumor infiltrating NK cells from esophageal cancer patients. a Representative FACS plots of NK (CD3−CD56+) cells in paired PBMC and TIL from a patient with esophageal cancer. b The percentages of total NK cells were quantified in paired PBMC and TIL from esophageal cancer patients (n = 36). c Representative FACS plots of CD39+ NK cells in paired PBMC and TIL from a patient with esophageal cancer. d The percentages of CD39+ NK cells in paired PBMC and TIL from patients with esophageal cancer (n = 36). *p < 0.05; ***p < 0.001
