Figure 1 OE33P and R cell lines were screened for the surface expression of immune checkpoints by flow cytometry. Inhibitory immune checkpoints are expressed at a higher level on parental cell lines than the passage matched radioresistant cell line (n = 3). A: PD-1; B: PD-L1; C: PD-L2; D: TIGIT. Graph shows % expression (± SE). aP < 0.05; bP < 0.01; cP < 0.001 by unpaired parametric t-test.
