Background Metabolic syndrome (MetSyn) is diagnosed frequently in some but not all overweight adolescents. Chronic inflammation, as seen in obesity, is strongly associated with MetSyn. Objectives The aim of this pilot study was to assess the correlation between activation of the innate immune system and MetSyn, independent of body mass index (BMI), in a young population. Methods We quantitatively measured both systemic pro-inflammatory cytokines and gene expression of Toll-like receptors (TLRs) and downstream cytokines in circulating monocytes obtained from nine adolescents with metabolic syndrome (Overwt-MetSyn) and eight BMI-matched controls (Overwt-Healthy). Results The Overwt-MetSyn group demonstrated a significant elevation in expression of TLR2, TLR4, tumour necrosis factor-a (TNF a) and interleukin-6 (IL6) in peripheral monocytes, and increased circulating levels of TNF a and IL6 when compared with the Overwt-Healthy group. TLR2 (r?=?0.78, P?
