The ligands for CXCR3 are increased in many tumours and associated with the intralesional accumulation of TILs and improved outcome (Slaney et al, 2014; Nagarsheth et al, 2017) and Cxcl9 and Cxcl10 (Cxcl11 is not expressed in C57BL/6 mice; Sierro et al, 2007) were elevated in the HER‐2‐E0771 tumours analysed at 10 days after implantation (Fig 6E). This evidence concerns the gene CXCL9 and neoplasm.
