The Effect of Beta Interferon on Dendritic Cells and Cytokine Synthesis by CD4+ T Cells
Authors
Abstract:
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 factor and interleukin-4 with or without IFN-β. We analyzed the production of CD4+ T helper cytokines (IL-17, IFN- γ and IL-10) in the supernatant of the dendritic cell-T cell co- cultures by ELISA. We also studied the effects of HLA-G and costimulatory molecules on immature and mature DC. Results: IFN-γ and IL-17 decreased significantly in the presence of HLA-Gbearing DC compared to control cultures (p

Background: During antigen capture and processing, mature dendritic cells (DC) express large amounts of peptide-MHC complexes and accessory molecules on their surface. DC are antigen-presenting cells that have an important role in tolerance and autoimmunity. The transforming growth factor-beta1 (TGF-β1) cytokine has a regulatory role on the immune and non-immune cells. The aim of this study is ...

Background: Polycystic ovary syndrome (PCOS) is considered as the most common cause of female infertility that affects 4-10% of women in the reproductive age. Previous studies have shown the role of a balanced immune response in a successful pregnancy and fertility. Objective: To investigate the T helper cells type 1 (Th1) /Th2/Th17/Treg paradigms in peripheral blood of infertile PCOS compared ...

Background: T-2 toxin is a mycotoxin of type A trichothecenes produced by several fungal genera such as Fusarium species. Mycotoxins can affect both cell mediated and humoral immune compartments. Objective: The purpose of this study was to investi-gate the effect of T-2 toxin on cytokine production by mouse peritoneal macrophages and lymph node T cells. Methods: Mouse peritoneal macrophages and...

BACKGROUND Glucan is an immunomodulating agent used for cancer therapy. We investigated the effects of glucan on immune cell response to prostate carcinoma. METHODS Dendritic cells (DC) were co-cultured with prostate carcinoma cells LNCaP and/or glucan, and maturation markers expression, cytokine release, and superoxide anion production were evaluated. Conditioned media from glucan-treated or...
