Cell morphology was observed under light microscopy. Cell surface molecules, including HI_A-DR, CD80, CD83, and CDla, were analyzed with flow cytometry. The concentrations of IL-6 and IL-12 in the supernatant were assayed by ELISA. T cell proliferation was assayed by methyl thiazoM tetrazolium (MTT).RESULTS: The expression of CDlα on DC treated with 0.5 mmol/L LAM (LAM-DC 0.5 mmol/L) was significantly higher than that of DC untreated with LAM (54.1 ± 4.21 vs 33.57 ± 3.14, P 〈 0.05), and so was the expression of CD83 (20.24 ± 2.51 vs 12.83 ± 2.12, P 〈 0.05) as well as the expression of HLA-DR (74.5 ± 5.16 vs 52.8 ± 2.51, P 〈 0.05). Compared with control group, LAM-DC group (0.5 mmol/L) secreted significantly more IL-12 (910 ± 91.5 vs 268 ± 34.3 pg/mL, P 〈 0.05), had lower levels of IL-6 in the culture supernatant (28 ± 2.6 vs 55 ± 7.36 pg/mL, P 〈 0.05), markedly enhanced the stimulatory capacity in the allogeneic mixed leukocyte reaction (MLR) (1.87 ± 0.6 vs 1.24 ± 0.51, P 〈 0.05).CONCLUSION: The lower expression of phenotypic molecules and impaired allogeneic mixed lymphocyte reaction function of dendritic cells derived from patients with HBV infection could be restored in vitro by incubation with LAM.展开更多
