Design: Cross-sectional study. Subjects: Twenty-six obese women (age 20-52 years, body mass index (BMI): 30-48 kg/m2) and 20 healthy lean women (age 23-46 years, BMI: 18-25 kg/m2). Measurements: Plasma levels of cytokines and leptin, BMI, waist circumference (WC) and insulin resistance index HOMA (homeostatic model assessment). Results: Blood concentrations of IL-17, IL-23, MIF and leptin, but not IL-12 or IFN-γ, were higher in obese compared with lean women (P=0.002, 0.046, 0.006 and 0.002, respectively). There was a positive correlation between IL-17 and IL-23 (r s=0.530), which was at the border of statistical significance (P=0.065). Neither IL-17 nor IL-23 correlated with leptin or MIF, and there was no association between IL-17 and IL-23 levels with BMI, WC or HOMA index. Conclusion: Interleukin-23/IL-17 axis is stimulated in obese women independently of the increase in abdominal fat, insulin resistance, leptin and MIF levels. © 2009 Macmillan Publishers Limited All rights reserved.CytokineIL-17IL-23InflammationLeptinMIFIncreased activity of interleukin-23/interleukin-17 proinflammatory axis in obese women
