CCL15, a human CC chemokine, was isolated from a human fetal spleen cDNA library. CCL15 cDNA encodes a predicted 113 amino acid (aa) protein containing a putative signal peptide of 21 aa that is cleaved to generate a 92 aa residue mature protein. Within the CC family members, human CCL15 shares 45%, 44%, 35%, and 30% aa homology with mouse C10, human MPIF1, human HCC1, and mouse MIP1γ, respectively. The gene for MIP1δ is found on chromosome 17 where the genes for most of the human CC chemokines are located. Human CCL15 is expressed in T and B lymphocytes, NK cells, monocytes and monocytederived dendritic cells. Human MIP1δ is chemotactic for T cells and monocytes and has been shown to induce calcium flux in human CCR1transfected cells.

CCL16, also known as HCC-4, is a CC chemokine that interacts with CCR1, CCR2, and CCR5. CCL16 is expressed weakly by NK cells, γδ T cells, and some T cells and is upregulated in monocytes by IL-10. CCL16 functions as a chemoattractant for monocytes and promotes the maturation of monocyte derived dendritic cells.

CCL17 is a novel CC chemokine identified using a signal sequence trap method. CCL17 cDNA encodes a highly basic 94 amino acid (aa)residue precursor protein with a 23 aa residue signal peptide that is cleaved to generate the 71 aa residue mature secreted protein. Among CC chemokine family members, CCL17 has approximately 24-29% amino acid sequence identity with RANTES, MIP1α, MIP1β, MCP1, MCP2, MCP3, and I309. The gene for human CCL17 has been mapped to chromosome 16q13 rather than chromosome 17 where the genes for many human CC chemokines are clustered. CCL17 is constitutively expressed in thymus, and at a lower level in lung, colon, and small intestine. CCL17 is also transiently expressed in stimulated peripheral blood mononuclear cells. Recombinant CCL17 has been shown to be chemotactic for T cell lines but not monocytes or neutrophils. CCL17 was identified to be a specific functional ligand for CCR4, a receptor that is selectively expressed on T cells.
