CCR5 and neoplasm: Thus in this study, to understand such roles of CCR2 and CCR5 in PDAC, using the above deidentified, existing RNAseq data, we performed correlative analysis of the gene expression of markers of relevant immune cell types and the differential expression of CCR2 and CCR5 genes in CD11b+, CD4+, and CD8+ cells sorted from the tumor-infiltrating immune cells in the above PDAC specimens resected from patients who received GVAX or GVAX + nivolumab.
