background: mesenchymal stem cells (mscs) possess a wide range of immunomodulatory functions mostly in immune cells including dendritic cells (dcs). dcs are the key cells in the immune response and play an important role in initiating cell-mediated immunity. objective: to evaluate the immunomodulatory effects of mscs supernatant on maturation and function of dcs. methods: bone marrow derived mi...

Objective(s): In addition to pro-inflammatory role, dendritic cells (DCs) can also be anti-inflammatory when they acquire tolerogenic phenotype. In this study we tested the role of CD40 and IL-23p19 in antigen presenting function of bone marrow-derived DCs (BMDCs) by comparing BMDCs derived from CD40 knockout (CD40KO-DCs) and IL-23p19 (IL-23p19KO-DCs) knockout mice wit...

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: 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...
