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...

IFN-kappa is a recently identified type I IFN that exhibits both structural and functional homology with the other type I IFN subclasses. In this study, we have investigated the effect of IFN-kappa on cells of the innate immune system by comparing cytokine release following treatment of human cells with either IFN-kappa or two recombinant IFN subtypes, IFN-beta and IFN-alpha2a. Although IFN-alp...

results the frequencies of the aa, at, and tt genotypes were 31%, 51%, and 18% in the chronic hbv patient group, and 40%, 45%, and 15% in the healthy control group, respectively. however, a lack of association of the + 874 polymorphism in the ifn-γ gene of those with chronic hbv infection was found. evaluation of hbv association with this polymorphism was significant under the dominant genetic ...

Polystyrene nanoplastics (NP) are often found in aquatic environments. The accumulation of biota such as fish, shrimp, squid, shellfish, etc. can reduce the health humans who consume them. purpose this study was to observe red seaweed’s potential a source antioxidants improving immune system and reproductive rats (Rattus novergicus) exposed nanoplastics. Twenty-five norvegicus) were divided int...

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: Malassezia furfur is alipophilic yeast that causes skin disease. Objective: To evaluate the level of IL-10, IFN-γ and IL-12P70 in co-incubation of M. furfur grown on different forms of natural oils with PBMCs of healthy individuals. Methods: PBMCs were obtained from blood samples of normal volunteers. M. furfur was cultured in different culture media containing almond oil, fish oil,...

Hepatitis C virus (HCV) envelope glycoprotein-2 (E2) inhibits the interferon (IFN)–induced, double –stranded RNA activated protein kinase (PKR) via PKR eukaryotic initiation factor-2α phosphorylation homology domain (PePHD). Present study examined the genetic variability of the PePHD in patients receiving interferon therapy. The PePHD region from HCV genotype 1a/1b infected patients receiving I...

Background: IBD is a chronic inflammatory condition associated with damage to the intestinal mucosal barrier. Supplementation of yacon tubers has been known to give positive effect in intestinal health. Therefore, we conducted the study to investigate the effect of yacon tuber powder on Th1 activation pathway by evaluating IFN-γ levels and the number of goblet cells in the colon of colitis mous...
