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...

UNLABELLED Worldwide, approximately 160 million people are chronically infected with hepatitis C virus (HCV), seven distinct genotypes of which are discriminated. The hallmarks of HCV are its genetic variability and the divergent courses of hepatitis C progression in patients. We assessed whether intragenotypic HCV variations would differentially trigger host innate immunity. To this end, we st...

Background: Cyclosporine A (CYA) prevents graft rejection after transplantation, interferon-α (IFN-α ) is a natural cytokine prescribed in some types of malignancies and hepatitis C virus. However neurologic complication such as depression side effect chronic use these drugs. Melatonin apart from its on regulating the circadian rhythm, has potent antioxidant inhibits N-methyl-d-aspartic acid (N...

BACKGROUND Major depression is a frequent adverse effect of interferon-alpha (IFN-α) therapy. Although the indoleamine 2,3-dioxygenase (IDO) enzyme seems to be involved in the pathophysiology of IFN-α-induced depression, no pharmacogenetic study has investigated whether variation in the IDO gene modifies vulnerability to this adverse effect. METHODS A cross-sectional study assessing 277 hepat...

Interferon-β is an established treatment for patients with multiple sclerosis (MS) but its mechanisms of action are not well understood. Viral infections are a known trigger of MS relapses. Toll-like receptors (TLRs) are key components of the innate immune system, which sense conserved structures of viruses and other pathogens. Effects of interferon-β on mRNA levels of all known human TLRs (TLR...

The ability of regulatory T cells (Tregs) to promote immunological tolerance represents an important obstacle in cancer immunotherapy. We have recently discovered that the clinically established immunotherapeutic agent interferon α (IFNα) inactivates the suppressive functions of human Tregs. Here, we outline the mechanisms whereby IFNα mediates this important function and discuss its therapeuti...

Imatinib revolutionized gastrointestinal stromal tumor (GIST) treatment but median-progression-free-survival of unresectable/metastatic disease is < 2 y. B-RAF(V600)-mutated-melanoma responds to vemurafenib dramatically but median-progression-free-survival is < 9 mo. Combining imatinib with immunotherapy (peginterferon α-2b) in GIST showed significant induction of antitumor immunity and highly ...
