Abstract

Background: Various allergens and irritants induced the production of reactive oxygen species (ROS) in the well-established mouse dendritic cell (DC) line XS106 and this production of ROS was inhibited by antioxidants. Objective: To investigate the production and functions of ROS in mouse bone marrow-derived DCs (BM-DCs) by various haptens and irritants, we examined the production of ROS, the expression of surface molecules, and the production of interleukui-12 (IL-12) in mouse BM-DCs. Methods: Six to eight-week-old female C57/BL6 mice were used in this study. Mouse BM-DCs were co-cultured with DNFB, DNCB, TNBS, hydroquinone, NiSO 4, CoCl 2, MnCl 2, thimerosal, SDS, and BKC. The production of ROS and the expression of surface molecules (CD40, CD80, CD86, and MHC-II) were measured by flow cytometry in chemical-treated mouse BM-DCs. In addition, the cells were pretreated with antioxidants to determine whether the production of ROS can be inhibited. The production of IL-12 was also measured in DNCB and SDS-treated mouse BM-DCs using ELISA. Results: The production of ROS in mouse BM-DCs was induced by various allergens, including DNFB, DNCB, TNBS, hydroquinone, MnCl 2 and irritants like SDS, BKC. The expression of surface molecules was induced by various chemicals and NiSO 4 was the most potent inducer of surface molecules in mouse BM-DCs. The production of ROS in DNCB and SDS-treated mouse BM-DCs was partially inhibited by diphenylene iodonium, but not by rotenone, vitamin E, allopurinol, glutathione. The production of IL-12 was not detected in DNCB and SDS-treated mouse BM-DCs. Conclusion: The production of ROS was induced in mouse BM-DCs by various allergens and irritants. The expression of surface molecules was also induced by various chemicals. The production of ROS was partially inhibited by DPI. The production of IL-12 was not detected.
