CCR2 antibody

CCR2 is a receptor for several monocyte chemoattractant proteins (MCP1, MCP3, MCP4) that specifically govern monocyte chemotaxis. CCR2 transduces its downstream signals through increasing intracellular calcium ion levels. For example, MCP1 regulates the monocyte infiltration found in inflammatory diseases such as rheumatoid or the cellular inflammatory response to tumors. CCR2 is also an alternative co-receptor with CD4 for HIV1 infection.

CCR2, also known as CD192 (cluster of differentiation 192), is a chemokine receptor and is expressed by monocytes, activated T cells, B cells and natural killer cells. This protein is encoded by CCR2 gene in humans. CCR2 gene encodes two protein isoforms of a receptor for chemokines monocyte chemoattractant protein-1 (MCP1), MCP3 and MCP4.

Monocyte Chemoattractant Protein (MCP1) is a potent monocyte attractant, is a member of the CC chemokine subfamily. MCP1 exerts its effects through binding to G-protein-coupled receptors on the surface of leukocytes targeted for activation and migration. The role of MCP1 and its receptor, chemokine receptor-2 (CCR2), in monocyte recruitment during infection or under other inflammatory conditions is well known. Recent studies indicate that MCP-1 may play an important role in pulmonary inflammation.
