Influences of MMF on the presentation functions of in vitro cultured dendritic cells / 中华器官移植杂志

ABSTRACT

Objective To explore the influence of MMF on the presentation functions of in vitro cultured dendritic cells.Methods Bone marrow-derived dendritic cell progenitors from BalB/c mice were treated with MMF or without. The antigen-presenting capacities, antigen specific proliferation reaction, mixed lymphocyte reaction and antigen-specific hyporesponsiveness of T-cells were analyzed to investigate the influences of MMF on the presentation functions of dendritic cells.Results Treatment with MMF reduced the soluble antigen presenting capacities of DCs to T cells. The proliferation of syngeneic T cells co-cultured with MMF-DC was significantly depressed, and displayed a comparatively low level of MLR-sti- mulatory activity. The levels of T helper cells derived cytokines were depressed, too.Conclusion MMF has a suppressive influences on the antigen-presenting functions of in vitro cultured dendritic cells and promotes the tolerance-induction effect of DCp.
