Chemokine (C-C motif) receptor 7 (CCR7) is involved in lymphocyte recirculation through secondary lymphoid organs and moving lymphocytes and dendritic cells into distinct tissue compartments. CCR7 is called the Epstein-Barr-induced receptor because it mediates Epstein-Barr viral effects on B lymphocytes. CCR7 expression is up-regulated in mature dendritic cells, B cells infected with EBV, and in CD4+ cells infected with human herpes virus 6 and 7. Immature dendritic cells have been shown to express chemokine receptor 5 (CCR5) and migrate in response to macrophage inflammatory protein-1alpha (MIP-1alpha), whereas mature dendritic cells switch to CCR7 expression and respond exclusively to MIP-3beta and 6Ckine. Maturing dendritic cells upregulate CCR7, which drives their migration to the T-cell areas of the draining lymph nodes where antigen is presented to naive T cells. References: The UniProt Consortium.
