For example, CD123+ pDCs were found to selectively express CCR2, CMKLR1, and CXCR3, receptors known to be involved in DC maturation, trafficking and recruitment at tumor sites24–26 whereas XCR1 and CX3CR1, were selectively expressed by CD141+ mDCs and CD1c+ mDCs. This evidence concerns the gene CX3CR1 and neoplasm.
