Human Pulmonary and activation-regulated chemokine,CCL18 ELI

Chemotactic factor that attracts lymphocytes but not monocytes or granulocytes.

May be involved in B-cell migration into B-cell follicles in lymph nodes.

Attracts naive T-lymphocytes toward dendritic cells and activated macrophages in lymph nodes, has chemotactic activity for naive T-cells, CD4+ and CD8+ T-cells and thus may play a role in both humoral and cell-mediated immunity responses.
