objective: dendritic cells have a critical role in control and regulation of immune responses. it is believed that these cells can be used for the treatment of many diseases. one of the methods used in immunotherapy is based on generating of tolerogenic dendritic cells through inhibition of expression costimulatory molecules. cd40 is one of the costimulatory molecules, and inhibition of express...

Background and purpose: As professional antigen- presenting cells, dendritic cells are a bridge between innate and adaptive immunity by stimulating T lymphocytes. Recent research has demonstrated the extra ability of the myeloid cells plasticity into different cells in response to environmental stimuli. In the present study, the effect of using combination maturation factors (MCM, TNF-α, poly (...
Background and purpose: Dendritic cells are professional antigen presenting cells that initiate and modulate immune responses. Epigallocatechin gallate (EGCG) is identified as a prophylactic agent that can suppress tumor formation. This research aimed at investigating the effect of EGCG on differentiation of dendritic cells from monocytes and as a potential substitute for IL-4 in this process. ...
The objective of the study was to identify immune cell populations, in addition to Foxp3+ T-regulatory cells, that participate in the mechanisms of action of tolerogenic dendritic cells shown to prevent and reverse type 1 diabetes in the Non-Obese Diabetic (NOD) mouse strain. Co-culture experiments using tolerogenic dendritic cells and B-cells from NOD as well as transgenic interleukin-10 promo...
Background: Type-1 diabetes (T1D) is an autoimmune disease in which T lymphocytes destroy insulin-producing β-cells. Control of self-reactive T lymphocytes and recovery of diabetic injury is the end point of T1D. Objective: To investigate generation of tolerogenic dendritic cells (tolDCs) as an innovative method of diabetes therapy. Methods: Lentivirus vector production was achieved by GIPZ mou...
cd40 is recognized as a member of tumor necrosis factor receptor super family. it is expressed by the immune and non-immune cells. its interaction with cd40 ligand (cd154) brings about a regulatory effect on the cellular and humoral immunity. the pathway of cd40-cd154 is influential in various diseases. investigations on such diseases have revealed dimensional mechanisms whereby this route in...
Dendritic cells (DCs) have several functions in innate and adaptive immunity. In addition, there is increasing evidence that DCs in situ induce antigen-specific unresponsiveness or tolerance in central lymphoid organs and in the periphery. In the thymus DCs generate tolerance by deleting self-reactive T cells. In peripheral lymphoid organs DCs also induce tolerance to antigens captured by recep...
