In contrast, the tumor-derived chemokine ligand CXCL10 can promote the expansion of Vδ1+ γδ Treg cells that infiltrate solid tumors and induce immune senescence in DCs, and prevent DC maturation (by inhibiting CD80, CD83, CD86, and HLA-DR expression), DC function (decreased IL-6 and IL-12 production), and DC phenotype (inability to stimulate naïve T-cell proliferation) via the TLR8 signaling pathway or by killing of DCs through a perforin-mediated pathway (102–107) (Figure 2). Here, PRF1 is linked to neoplasm.
