External PDAC datasets supported these findings, i.e., single-cell RNA-seq showed that CXCR3 is mainly expressed by tumor-infiltrating CD8+-T-cells (Fig. S3E), and TCGA data analysis found that CXCR3 expression correlated strongly with activated/effector memory CD8+-T-cells (Fig. S3F, Table S4). Here, CXCR3 is linked to neoplasm.
