CXCL9 promoted tumour progression in murine orthotopic PAAD model. (A) showed CXCL9 accelerated tumour growth of orthotopic murine PAAD in mice; (B) showed the increased luciferin signals detected in mice was speeded up by CXCL9 treatment; (C) showed CXCL9 treatment increased tumour weight of orthotopic murine PAAD; (D) showed that CXCL9 treatment led to more aggressive pattern of tumour cells in orthotopic murine PAAD; immunohistological analysis confirmed that CXCL9 treatment could increase the intratumoral CXCL9 level (black arrow)while reduce the CD8+ cytotoxic T cells (white arrow); (E) showed that CXCL9 treatment had minimal effect on the pattern of innate immune cells in the tumour microenvironment; (F) showed that CXCL9 treatment significantly reduced the CD8+ cytotoxic T cells without affecting other adaptive immune cells in the tumour microenvironment of PAAD. *p<0.05, **p<0.01, ***p<0.001 when compared with control.
