Among the overexpressed signatures, we identified substantial enrichment in immune‐related pathways, including IDO1 (Indoleamine 2,3‐dioxygenase 1), TIGIT (T cell immunoreceptor with Ig and ITIM domains), Treg (Regulatory T cell), TIS (Tumor Inflammation Signature), CD8 (Cluster of differentiation 8 lymphocyte marker), PD‐1 (Programmed cell death protein 1), inflammatory chemokines, IFN‐γ (Interferon gamma), PD‐L1 (Programmed death‐ligand 1), PD‐L2 (Programmed death‐ligand 2) and macrophages. This evidence concerns the gene TIGIT and neoplasm.
