Both TARC and CTACK serum levels in patients with AD were significantly higher than those in healthy control subjects and patients with allergic respiratory disease.
Our results suggest that the primary Th2-dominated inflammatory reaction in AD induced by TARC leads to an augmented skin-specific inflammatory reaction through CTACK.
The purpose of this study was to investigate serum levels of Th2 chemokines TARC and MDC and a Th1 chemokine Mig in the same samples from patients with AD and their clinical correlation.
Furthermore, we found that TARC and MDC levels are significantly increased in the sera obtained from patients with atopic dermatitis, and that the amounts are correlated with the severity of atopic dermatitis.
TGF-beta1 inhibited IFN-gamma and TNF-alpha-induced TARC production in HaCaT cells via Smad2/3, suggesting that modulation of TGF-beta/Smad signaling pathway may be beneficial for the treatment of atopic dermatitis.
