The pDCs frequency in liver infiltrating lymphocytes in severe CHB patients was significantly higher than those in healthy controls, which was further confirmed by in situ immunohistochemical staining. Though pDCs frequency of LILs was higher than those in PBMCs in severe CHB patients, however, the LILs generated less amounts of IFN-a compared with the PBMCs under the same stimulation of CpG ODN, suggesting pDCs was, at least in part, dysfunctioned in the liver of severe CHB patients.

2与健康人比较，慢性乙型肝炎病人外周血中pDCs和NK细胞频率明显下降，并且CpG ODN2216刺激PBMCs产生IFN-α的能力也显著降低；相关性分析表明，慢性乙肝病人pDCs频率与ALT呈明显负相关，但与血浆病毒载量无明显相关。
