Abstract
Although CD34+ progenitor-derived immature dendritic cells (DCs) express CCR6, several recent studies reported that monocyte-derived immature DCs do not do so. We observed that DCs generated from monocytes in the presence of GM-CSF, IL-4, and TGF-beta 1 consistently responded to liver and activation-regulated chemokine (LARC, also known as macrophage inflammatory protein-3 alpha). These immature DCs expressed one class of high-affinity binding sites for LARC, and expressed both CCR6 mRNA and protein. Therefore, LARC-CCR6 interaction presumably also contributes to the regulation of trafficking of monocyte-derived DCs, and utilization of TGF-beta can potentially provide a ready source of CCR6+ monocyte-derived DCs for therapeutic purposes.Entities:
