CXC chemokines expression was correlated with prognosis and immune cell patterns of PAAD. (A) showed the Heatmap expression patterns of CXC chemokines in PAAD extracted from the GEO database (GDS4102); (B) showed CXC chemokines with significant changes in expression in PAAD; (C) showed CXC chemokines whose expression was correlated with overall survival of PAAD patients; (D) showed the correlation of selected CXC chemokines with the immune cell patterns in the tumour microenvironment; (E) showed the expression pattern of CXC chemokine receptors, CXCR2, and CXCR5, in different types of immune cells. *p<0.05, ***p<0.001 when compared.
