Background: Dendritic cells (DCs) are professional antigen presenting cells (APCs), and there is considerable interest in their application as a cellular adjuvant for cancer immunotherapy.  Previous studies indirectly demonstrated that DCs were able to take up tumor lysate (crude soluble tumor antigens) and also cross-present tumor associated antigens (TAA) which elicits anti-tumor immune respo...

Background: Leishmania is a pathogenic parasite which infects mononuclear cells in vertebrate hosts. Different strategies have been taken to develop immunity against Leishmania . DCs loaded with immunogenic antigen have resulted in different levels of Th1-type immune response and cytotoxic T lymphocytes (CTL) activity. Objective: To evaluate the potency of DCs primed with soluble Leishmania mex...

dendritic cells (dcs) play an important role in induction of cellular immune responses. it seems that dcs that reside in different organs may be distinct in their ability to  induce immune responses. this study was done to address the differences between spleen and liver dcs in induction of immune response and/or tolerance. cd11c+  dcs were separated from the liver and spleen of c57bl/6 mice an...

Introduction Dendritic cells (DCs) are bone marrow-derived cells, which migrate to lymphoid and non-lymphoid organs via blood. Liver DCs are believed to play an important role in the regulation of hepatic allograft acceptance. However, because of inherent difficulties in isolating adequate numbers of DCs from liver, limited information is available on the phenotype and functions of liver DCs. ...

Background: Generation of an effective dendritic cell (DC) based cancer vaccine depends on appropriate differentiation of monocytes in vitro. Objective: To compare the effects of monocyte separation methods, flask adherence (Flask-DC) and magnetic activated cell sorting (MACS-DC), on phenotypic and functional characteristics of resultant DCs. Methods: DCs from healthy volunteers were generated ...

Dendritic cells (DCs) are a heterogeneous family of professional APCs involved in priming adaptive immune responses. Donor DCs (direct pathway of allorecognition) and recipient DCs presenting processed donor major histocompatibility complex (MHC) as peptides (indirect pathway of allorecognition) participate actively in graft rejection by stimulating recipient T cell responses following organ tr...

Background: Bacterial DNA has immunostimulatory effects on different types of immune cells such as dendritic cells (DCs). Application of DCs as a cellular adjuvant represents a promising approach in the immunotherapy of infectious disease and cancers. Objectives: To investigate the effect of tumor antigen pulsed DCs in the presence of CpG-1826 in treatment of a murine model of cancer. Methods: ...

Background: Generation of monocyte-derived dendritic cells (MDDC) is induced in the presence of GM-CSF and IL-4, and a maturation stimulus is added to the monocyte culture to obtain mature Dendritic Cells (DCs) suitable for therapy. TNF-α is the most common cytokine used for activating DCs and generating mature MDDC either alone or in combination with other cytokines. Objective: To compare effe...

As the sentinels of innate and adaptive immune system, dendritic cells (DCs) have been considered to hold a great promise for medical application. Among diverse types DCs, monocyte-derived DCs (mo-DCs) generated in vitro most commonly employed. We improving culture protocol devised produce mature interferon-α-induced (IFN-DCs), hereinafter called (mat)IFN-DCs. While exploring relationship betwe...
