Feline CCL7 (C–C motif chemokine ligand 7, also known as MCP-3 – monocyte chemoattractant protein-3) is a proinflammatory chemokine that regulates leukocyte recruitment and inflammatory responses in cats (Felis catus). CCL7 is a member of the CC chemokine family, which includes related chemokines such as CCL2 (MCP-1), CCL8 (MCP-2), and CCL13 (MCP-4) that function in monocyte and leukocyte trafficking during immune activation. In cats, CCL7 is produced by macrophages, fibroblasts, endothelial cells, epithelial cells, and other immune cells in response to infection, inflammatory cytokines, or tissue injury. CCL7 exerts its biological effects through interaction with several chemokine receptors, including CCR1, CCR2, and CCR3, promoting chemotaxis and activation of monocytes, macrophages, dendritic cells, T lymphocytes, and eosinophils at sites of inflammation. In feline health, CCL7 contributes to immune responses against viral and bacterial infections and plays roles in inflammatory and immune-mediated diseases by coordinating recruitment of immune cells to affected tissues. Because chemokine-driven leukocyte migration is critical for host defense and inflammatory regulation, feline CCL7 is studied in veterinary immunology, infectious disease research, and inflammatory disease models, helping to improve understanding of chemokine signaling and immune cell trafficking in cats.
