背景 | MIP-3 beta, also known as ELC (EBI1-Ligand Chemokine), is one of many novel beta chemokines identified through bioinformatics. MIP-3 beta cDNA encodes a 98 amino acid (aa) residue precursor protein with a predicted 21 aa residue signal peptide that is cleaved to form the 77 aa residue mature secreted protein. MIP-3 beta is distantly related to other beta chemokines (20-30% aa sequence identity) and 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 has been shown to be 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. MIP-3 beta has been shown to be a unique functional 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. EBI1 is strongly up-regulated in B cells infected with Epstein-Barr virus and T cells infected with herpesvirus 6 or 7. |

Chemotaxis Induced by CCL19/MIP-3 beta and Neutralization by Human CCL19/MIP-3 beta Antibody. Recombinant Human CCL19/MIP-3 beta (Catalog # 361-MI) chemoattracts the BaF3 mouse pro-B cell line transfected with human CCR7 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Human CCL19/MIP-3 beta (50 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human CCL19/MIP‑3 beta Monoclonal Antibody (Catalog # MAB3611). The ND50 is typically 0.1-0.5 µg/mL. |
