The Effect of Beta Interferon on Dendritic Cells and Cytokine Synthesis by CD4+ T Cells
Background: Dendritic cells (DC) are a key regulator of the immune response, and interferon- beta (IFN-β) is considered an immunomodulatory molecule for DC. Objective: The purpose of this study was to evaluate the ability of IFN-β treated DC to induce cytokine secretion by CD4+ T cells. Methods: Dendritic cells were generated from blood monocytes with granulocyte-monocyte colony-stimulating fac...

Background & Aim: Tolerance to the semi-allogenic fetal graft by the maternal immune system is a medical enigma that has stimulated investigations for a half of century. Several hypotheses have been proposed to explain the tolerance of mother to the fetus. The successful pregnancy is proposed and proved by many scientists to be a Th2 dominant phenomenon. This hypothesis is proved in most as...
متن کاملImmediate Exposure to TNF-α Activates Dendritic Cells Derived from Non-Purified Cord Blood Mononuclear Cells
Background: Tumor necrosis factor alpha (TNF-α) is a primary mediator of immune regulation and might be required in the early stages of DC development from CD34+ cells. However, details of optimal timing of exposure to TNF-α in DC development process in monocytes or non-purified hematopoitic cells are still lacking and clear benefits of this approach to the development of DCs remain to be valid...
متن کاملEvaluation of the Immunomodulatory Effect of Curdlan on Maturation and Function of Mouse Spleen-Derived Dendritic Cells
Background: T helper 1 and T helper 17 cells play important roles in immunity against foreign invaders. Differentiation of these Th subsets is affected by state of maturation and cytokines that are produced by dendritic cells (DCs). Curdlan is a linear (1→3)-β- glucan and has shown activity against tumors and infectious agents. Objective: This study aims to investigate whether curdlan plays its...

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 (...
