Abstract: 

Introduction: Dendritic cells are professional antigen presenting cells that obtain necessary regulatory signals for T cells. T regulatory cells are effective cells in reaction with dendritic cells and have an important role in treating of diseases.
Objective: To evaluated the effect of TGF-
b(Trancforming Growth Factor b) Cytokine in dendritic cell generation and capacity of these cells in regulatory T cells development in culture media.
Materials and Methods: In this experimental study, blood samples were obtained from 5 volunteers, then peripheral blood mononuclear cells were isolated by using Phicole Hypaque, dendritic cells of peripheral blood monocyte were produced by GM-CSF, IL-4 and TGF
b- in comparison with control group. Mixed leukocyte reaction was accesed in allogenic T cell and dendritic cell. The number of CD4+CD25+T cells, CD14+and their surface markers were evaluated by Flowcytometry.
Results: In this study, dendritic cells produced in presence and without presence of TGF
b- cytokine. The proliferation level of T cells decreased in mixed leukocyte reaction with dendritic cell-treated TGF b- in comparison with control group. In addition, the number of T CD25+cells increased 27 percent in culture media including dendritic cell-treated TGF b- in comparison with control group (p<0.05) .
Conclusion: The TGF-Beta molecule caused effect on the dendritic cells and producted cells with inhibiting of immune responses in mixed leukocyte reaction. So it concluded that, these cells can be have an important role in preventing of unwanted immune reaction invitro.
