CCL12

CCL12, also known as monocyte chemotactic protein 5 (MCP-5), belongs to the CC chemokine cluster on mouse chromosome 11. CCL12 is a potent peripheral blood mononuclear cell chemokine that attracts eosinophils, monocytes and lymphocytes but not neutrophils. It induces calcium flux in peripheral blood mononuclear cells, but not in purified mouse eosinophils or neutrophils. CCL12 is a potent monocyte-active chemokine that signals through CCR2. Involved in allergic inflammation and host response to pathogens, and may play a key role in the early stages of allergic pulmonary inflammation[1][2].
