Background: Dendritic cells (DCs) are professional antigen presenting cells that have an important role in the initiation of immune response. The use of maturation factors in dendritic cell differentiation provides a promising approach in immunotherapy. Objective: In this study, we compared tumor necrosis factor-α, polyribocytidylic acid, lipopolysacharide and CpG oligonucleotides in inducing d...

objective: dendritic cells (dcs) play a critical role in the beginning and in the course of immune responses. by observing. considering the defect in these cells in patients with tumor malignancy. in recent years there has been considerable interests in correction and use of these cells. in our prvious studies we showed that lysate of listeria monocytogenese can induce maturation of dendritic c...
allergen-specific immunotherapy (ait) has been recently considered as an alternative approach to ameliorate the symptoms of allergen exposure and improvement the patients’ quality of life. dendritic cells (dc) in the forms of tolerogenic or th1-induced cells have been investigated in several studies as one of the promising approaches of ait in allergic diseases. the aim of this study was to eva...
Background & Objectives: Interaction of cytomegalovirus glycoprotein B with toll-like receptors of dendritic cells leads to early signaling and innate immune responses. The aim of this study is to evaluate the effects of cytomegalovirus glycoprotein B on the maturation and function of monocyte-derived dendritic cells in treated groups in comparison with control groups. Materials & Methods: Bloo...
introduction: decidua as the nearest mother's tissue layer to the fetus which is in direct contact with the embryo has an important role in composing the appropriate microenvironment for protection of allogenic fetus from mother's immune response. in this study the effect of supernatant from culture of decidual cells on dendritic cells regarding the induction of t-cell allogenic proliferation r...
Background: Nowadays, dendritic cells (DCs) have a special place in cancer treatment strategies and they have been used for tumor immunotherapy as they can induce immune response against tumor cells. Researchers have been trying to generate efficient dendritic cells in vitro therefore, this research was done to generate them for use in research and tumor immunotherapy. Methods: This study took...
Background & Aims: Dendritic cells are the most potent antigen presenting cells in induction or polarization of T-dependent immune responses. In cancerous patients, suppressive or detoured immune responses regard to tumor cells, prevent appropriate functions of dendritic cells. Nowadays, in vitro production, expansion and maturation of dendritic cells in presence of safe maturation factors whi...
Background & Objectives: Chronicity of lupus nephritis (LN) should be considered for interaction of cell mediated immunity (CMI) and dendritic cells in glomeruli and tubulointerstitial areas. In this study establishment of immunohistopathological changes of dendritic cells and other immune effector cells in lupus nephritis comparing with non-lupus nephritis was performed. Materials & Methods: ...
