Correlation between TDO2 and PD-L1 expression. a Immunohistochemistry of TDO2 and PD-L1. Left picture, cytoplasmic staining of TDO2. Right picture, membranous staining of PD-L1. Original magnifications × 100. b Correlation between PD-L1 staining and TDO2 expression score. Wilcox test. c, d In silico analysis of the correlation between TDO2 and PD-L1 and T-cell exhaustion signature genes. c TDO2 expression correlated with PD-L1 expression. d TDO2 expression correlated with T-cell exhaustion signature genes (CLTA4, PDCD1, GZMB, LAG3). Unit: log2(count+ 1). Spearman rank correlation test
