From: A novel transcriptional signature identifies T-cell infiltration in high-risk paediatric cancer
High-risk paediatric cancers are predominantly PD-L1 negative. a Representative immunohistochemistry (IHC) images for PD-L1 in a control, positive and negative tumour. b Number of PD-L1-negative and PD-L1-positive samples with cancer category highlighted. c PD-L1− (< 1%) and PD-L1.+ (≥ 1%) by IHC compared to PD-L1 expression by RNA-seq (TPM, transcripts per million) in CNS (red) and extracranial tumours (blue)
