Background: CCL19/MIP-3 beta

CCL19, also known as MIP-3 beta and ELC (EBI1-Ligand Chemokine), is a 77 amino acid (aa) beta chemokine that is distantly related to other beta chemokines (20-30% aa sequence identity). The gene for MIP-3 beta has been mapped to chromosome 9p13 rather than chromosome 17 where the genes for many human beta chemokines are clustered. MIP-3 beta is constitutively expressed in various lymphoid tissues (including thymus, lymph nodes, appendix and spleen). The expression of MIP-3 beta is
down‑regulated by the anti-inflammatory cytokine IL-10. Recombinant MIP-3 beta is chemotactic for cultured human lymphocytes. MIP-3 beta is a ligand for CCR7 (previously referred to as the Epstein-Barr virus-induced gene 1 (EBI1) orphan receptor), a chemokine receptor that is expressed in various lymphoid tissues and activated B and T lymphocytes. CCR7 is strongly up-regulated in B cells infected with Epstein-Barr virus and T cells infected with herpesvirus 6 or 7.
