Chemokine CCL18

**Definition:** A CC-type chemokine highly expressed in the lungs, lymph nodes, placenta, and bone marrow; it is also expressed by DENDRITIC CELLS in the GERMINAL CENTER, and peripheral blood MACROPHAGES. It functions as a chemotactic factor that specifically attracts LYMPHOCYTES, especially B-Cells, into lymph node follicles, and naive T-cells towards dendritic cells and activated T-cells. It does not attract MONOCYTES or GRANULOCYTES.
