Abstract

Dendritic cells (DCs) are professional antigen-presenting cells, which have the extraordinary capacity to initiate naïve T-cell-mediated primary immune responses. To investigate the role of DCs in the induction of antigen-specific tolerance, the immature DCs (imDCs) and mature DCs (mDCs) were generated in vitro from lin CD117(c-kit)+ stem cells isolated from mice bone marrow. Flow cytometry and confocal microscopy were used to characterize the phenotypes of DCs. These cells were loaded with nuclear antigen derived from Trypanosoma equiperdum and then co-cultured with naïve CD4+ T cells. It was found that imDC-treated T cells had lower proliferation level and cytokine expression of interleukin (IL)-2, IL-4, IL-12, and interferon-γ compared with mDC-treated T cells. These results demonstrated that the maturation status of DCs is critical for preventing the production of autoantibodies.
