摘　　要：Background： Plasmacytoid dendritic cells （pDCs） and cytokines play an important role in occurrence and recovery of hepatitis B virus （HBV） infection. The aim of this study was to explore the frequency and function ofpDC and serum cytokine network profiles in patients with acute or chronic HBV infection. Methods： The healthy individuals （HI group）, hepatitis B envelope antigen （HBeAg）-positive chronic HBV patients in immune tolerance （IT） phase （IT group）, HBeAg-positive chronic HBV patients （CHB group）, and acute HBV patients （AHB group） were enrolled in this study. The frequency of cluster of differentiation antigen 86 （CD86） ＋ pDC and the counts of CD86 molecular expressed on surface ofpDC were tested by flow cytometer. The quantitative determinations ofcytokines, including Fins-like tyrosine kinase 3 ligand （FIt-3L）, interferon （1FN）-α2, IFN-γ, interleukin （IL）-17A, IL-6, IL-10, transforming growth factor （TGF）-β1 and TGF-β2, were performed using Luminex multiplex technology. Results： In this study, there were 13 patients in HI group, 30 in IT group, 50 in CHB group, and 32 in AHB group. Compared with HI group, HBV infected group （including all patients in IT, CHB and AHB groups） had significantly higher counts of CD86 molecular expressed on the surface ofpDC （4596.5 ± 896.5 vs. 7097.7 ± 3124.6; P 〈 0.001）. The counts of CD86 molecular expressed on the surface of pDC in CriB group （7739.2 ±4125.4） was significantly higher than that of IT group （6393.4 ± 1653.6, P=0.043）. Compared with IT group, the profile of cytokines of FIt-3L, IFN-γ, and IL-17A was decreased, IFN-α2 was significantly increased （P =0.012） in CH B group. The contents of IL-10, TGF-{31, and TGF-132 in AHB group were significantly increased compared with IT and CHB groups （all P 〈 0.05）. Conclusions： This study demonstrated that the function of pDC was unaffected in HBV infection. The enhanced function of pDC and IFN-α2 might involve triggering Background： Plasmacytoid dendritic cells （pDCs） and cytokines play an important role in occurrence and recovery of hepatitis B virus （HBV） infection.
