Thirty patients with CIU, 30 patients with dermographism and 30 healthy controls were randomly enrolled. Reverse transcription-PCR (RT-PCR) was used to analyze the mRNA of cytokine receptors in peripheral blood mononuclear cells (PBMCs). The mRNA levels of tumor necro- sis factor receptor (TNFR), interferon-7 receptor (IFN-yR), and interleukin-10 receptor (IL-IOR) were statistically increased in the CIU group (P 〈 0.05), while IL-2R, IL-4R, IL-6R, and IL-13R showed no significant differences between the CIU and other groups. The mRNA levels of CCR3 and CCR6 were statistically increased in the CIU group (P 〈 0.05). The toll-like receptor 2 (TLR2) mRNA level was significantly lower in the CIU group than the healthy control group (P 〈 0.05). These findings indicate that the regulation of mRNA of TNFR, IFN-γR, IL-IOR, CCR3, CCR6 and TLR2 may be involved in the pathogenesis of CIU.展开更多
