CXCL9 chemokine promotes the progression of human pancreatic adenocarcinoma through STAT3-dependent cytotoxic T lymphocyte suppression
Figure 4. CXCL9 suppressed in vivo proliferation and activation of CD8+ cytotoxic T cells. (A) showed in vivo CXCL9 treatment suppressed mRNA expression of anti-tumour cytokines IL2, TNFα, and IFNγ in CD8+ cytotoxic T cells; (B) showed that in vivo CXCL9 treatment suppressed serum level of anti-tumour cytokines IL2, TNFα, and IFNγ in orthotopic murine PAAD mice; (C) showed that in vivo, CXCL9 treatment significantly retarded the proliferation of CD8+ cytotoxic T cells; (D) showed that in vivo CXCL9 treatment significantly repressed expression of proliferation marker Ki67; (E) showed that in vivo CXCL9 treatment significantly repressed expression of activation marker Granzyme B. *p<0.05, **p<0.01, ***p<0.001 when compared with control.
