Figure 6

PD-L1 and PanCK expression showed a moderate positive Pearson's correlation coefficient indicating overlapping expression areas (A). The comparison of PD-L1 and PanCK with CD4 and CD8 immunoreactivity showed negative weak Pearson correlation coefficients, indicating that PD-L1 and PanCK are not expressed in the same location as CD4+ or CD8+ lymphocytes (B–E). The x and y axis are represented by (normalized) intensity, ranging from 0 to 255. Abbreviations: CD4: cluster of differentiation 4; CD8: cluster of differentiation 8; PanCK: pan cytokeratin; PD-L1: programmed cell death ligand 1.
