CCL8/MCP-2 was isolated from cytokine-stimulated human osteosarcoma cells (MG-63), identified by peptide sequencing, and shown to specifically attract monocytes but not neutrophils in vitro and in vivo (intradermal injection in rabbits). It was classified as a CC chemokine with conserved cysteine residues, structurally related to MCP-1. |

CCL8/MCP-2 actions on human monocytes include bimodal migration, N-acetyl-β-D-glucosaminidase release, and Ca2+ transients. Cross-desensitization showed MCP-1, MCP-2, and MCP-3 share a receptor subgroup on monocytes distinct from the RANTES/MIP-1α/MIP-1β subgroup, though MCP-2 also partially interacts with the latter. Radiolabeled MCP-1 binding was competed by all MCPs; MCP-3 (but not MCP-1/MCP-2) fully displaced MIP-1α. |

The CCL8/MCP-2 gene promoter region between -340 and -301 (relative to transcription start site) is required for IFN-γ-induced transcription in fibroblasts and osteosarcoma cells. The region -143 to -73 (containing putative GATA-1, H-APF1, AP-1, and GAS elements) is important for basal transcription. IL-1β alone failed to induce expression, but synergized with IFN-γ in osteosarcoma cells. Transcription factors in nuclear extracts were shown to bind the -340/-301 region by EMSA. |

Intact CCL8/MCP-2(1-76) produced by fibroblasts is processed into CCL8(6-75) under synergistic IFN-γ + IL-1β (or TLR ligand) stimulation. The truncated isoform CCL8(6-75) lacked chemotactic activity for monocytes and had severely reduced capacity to increase intracellular Ca2+ via CCR1, CCR2, CCR3, and CCR5. However, CCL8(6-75) still blocked these receptors, induced CCR2 internalization, inhibited MCP-1/CCL2 and MCP-2/CCL8 ERK signaling, and antagonized chemotactic activity of several CCR2 ligands. |
