CXCR3 and its ligands are upregulated in the tumour microenvironment. (a) Relative mRNA expression of chemokine receptors in CD4+ and CD8+ T cells isolated from PB and tumour tissue. The mRNA levels were assessed by real-time PCR and are presented relative to β-actin levels. (b) Flow cytometric analysis of CXCR3 expression in CD8+ T cells and CD8+ TEM cells from tumours. (c) Relative expression of chemokines in cultured PTY cells, skin and tumour. The mRNA levels were assessed as in (a).
