Objective: Interferon-α (IFN) therapy can cause depressive symptom which may lead to drug discontinuation. By interfering with tryptophan pathway, the available level of tryptophan required for serotonin synthesis decreases which could be related to depression. The aim of this study was to evaluate whether soybean diet could improve IFN-induced depression. Materials and Methods: Male mice weigh...

Interferon-gamma is produced by immune cells before MS exacerbations, and exogenous IFN-gamma treatment causes MS attacks. IFN-beta production, conversely, rises after exacerbations. IFN-beta therapy ameliorates MS, possibly by lowering IFN-gamma secretion and inhibiting responses to IFN-gamma. IFN-gamma effects are regulated by IFN-gamma receptor (IFNGR) expression. IFN-gamma is pro-inflammato...

multiple sclerosis (ms) is an inflammatory, multifocal, immune-mediated disease of the central nervous system that women are at a higher risk to acquire than men. myxovirus resistance protein a (mxa) is used as a predictive marker of bioactivity of interferon-beta (ifn-β) therapy in ms patients. this study was undertaken in west of iran to investigate gender differences in the expression level ...

Efficacy of B-cell depletion therapy highlights the antibody-independent effector functions B cells in rheumatoid arthritis (RA). Given type 1 helper T (Th1) abundant synovial fluid (SF) RA, we have determined whether Th1 could generate novel cells. Microarray and qPCR analysis identified CXCL9/10 transcripts as highly expressed genes upon BCR/CD40/IFN-? stimulation. Activated promoted generati...

Modern cancer immunotherapies largely focus on the ability of CD8+ cytolytic T cells to directly recognize and kill tumor cells. These strategies are limited by development an immunosuppressive microenvironment emergence immune evasive MHC-deficient or IFN-unresponsive CD4+ effector can contribute responses independent However, potential mechanisms cell-mediated anti-tumor immunity remain elusi...

Background: Management of multiple sclerosis (MS) is based on the usage of immunosuppressive and immune-modulating medications. Cytokines play an important role in the pathogenesis of MS. Objective: To evaluate the effects of rapamycin on the concentrations of Th1/Th2/Th17 serum cytokines in patients with MS. Methods: Six patients with relapsing remitting MS as a case group and 6 healthy indivi...

Background & Aims: Multiple sclerosis (MS) is one of the chronic autoimmune diseases of the central nervous system with unknown etiology. The present study aimed to investigate the apoptosis and nitric oxide (NO) production of endothelial cells treated with serum of patients with MS and response to interferon beta (IFN- ) therapy. Methods: Human umbilical vein endothelial cells were treated wit...

A 71-year-old female patient with hepatitis C virus genotype 1 had previously discontinued interferon (IFN)-α plus ribavirin therapy, pegylated IFN-α (pegIFN-α) monotherapy, and natural IFN-α monotherapy because of arrhythmia, interstitial pneumonia, and severe neurovegetative symptoms. She subsequently completed 72 weeks of natural IFN-β plus ribavirin therapy without remarkable adverse effect...

Although results of IFN alpha therapy in chronic hepatitis C (C-CH) patients co-infected with TT virus (TTV) have been reported, no results of IFN beta therapy or IFN beta and alpha combination therapy have been reported. In this study, we retrospectively investigated whether co-infection with TTV affects the results of IFN therapy by using stored sera from 60 C-CH patients co-infected with TTV...
