Cxcl9/10 are known chemoattractants for subsets of activated/memory T cells [89], and although there is no significant difference in total Cd3+ cells in WT vs. KO PC populations, we cannot exclude that KO PCs have increased subsets of activated/memory T cells or that these subsets increase more in KO PCs in response to tumor-secreted inflammatory mediators. This evidence concerns the gene CXCL9 and neoplasm.
