Chemokine (C-C motif) ligand 1 (CCL1) is a small glycoprotein secreted by activated T cells that belongs to a family of inflammatory cytokines known as chemokines.[1] CCL1 attracts monocytes, NK cells, and immature B cells and dendritic cells by interacting with a cell surface chemokine receptor called CCR8.[2] This chemokine resides in a large cluster of CC chemokines on human chromosome 17.
