Validation of correlation between CXCL5 expression and infiltration of M2 polarized macrophages, neutrophils and IgG+ plasma cells in pancreatic cancer from data of TCGA and GTEx. (A) Correlation analysis between CXCL5 and CD163 (R=0.26, p=0.00046, Spearman correlation analysis); (B) Correlation analysis between CXCL5 and CD15 (R=0.46, p=8.1× e-7, Spearman correlation analysis). (C) Correlation analysis between CXCL5 and IGHG1 (R=0.21, p=0.0039, Spearman correlation analysis). (D) Correlation analysis between CXCL5 and IGHG2 (R=0.2, p=0.0086, Spearman correlation analysis). Data was obtained from the GEPIA (http://gepia.cancer-pku.cn/).
