ABSTRACT
Background: To analyze the effects of IL-10 on the HLA-G expression and the apoptosis of trophoblasts infected with Toxoplasma gondii. Methods: T. gondii-infected or uninfected human trophoblasts and immortalized human placental BeWo cells were cultured with or without human IL-10. Uninfected and infected cells without IL-10 cells served as controls. HLA-G expression was measured by real-time PCR and flow cytometry, respectively. Cells apoptosis were analyzed by flow cytometry. Apoptosis associated moleculars were measured by real-time PCR and Western bolt. Results: HLA-G expression was increased in the infected trophoblasts and BeWo cells compared to uninfected cells. Treatment of infected cells with IL-10 decreased HLA-G expression compared to infected cells while no change in treatment of uninfected cells compared with uninfected cells. Levels of apoptosis and apoptosis associated caspase-3 and caspase-8 decreased and c-FLIP levels increased in treated infected cells with IL-10 compared to infected cells and no difference in IL-10 treated uninfected cells compared to uninfected cells. Conclusions: IL-10 regulates HLA-G expression in T. gondii-infected trophoblasts. IL-10 treatment of infected trophoblasts reduced levels of apoptosis. This may contribute to the improvement in pregnancy outcomes when women infected with T. gondii treated with IL-10.
