CCR6 and neoplasm: ,47AlloHSC-iNKT cells expressed exceedingly high levels of multiple tissue inflammatory homing marker genes (e.g., CCR1, CCR2, CCR3, CCR5, CCR6, and CXCR3), comparable to those of endogenous innate T cells (i.e., PBMC-iNKT and PBMC-γδT cells) but significantly higher than those of endogenous conventional αβ T and NK cells (i.e., PBMC-αβTc and PBMC-NK cells), suggesting a strong capacity of AlloHSC-iNKT cells to home to and penetrate tumor sites (Figure 2H).
