In 80 obese women, S-CCL18 levels were significantly higher in insulin resistant compared with insulin sensitive subjects. In WAT CCL18 mRNA was expressed in macrophages and correlated positively with immune-related genes, particularly those enriched in M2 macrophages. While CCL18 increased cyto-\/chemokine expression in M0\/M2-THP-1 cells, human adipocytes showed no responses in vitro.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions:<\/jats:title>\n                  <jats:p>Circulating and WAT-secreted CCL18 correlates with insulin resistance and metabolic risk score.
