Introduction: Interferon beta is one of the members of type I interferons. Creating R27T and V101F mutations is one of the important researches performed to improve function, decrease immunogenicity, increase expression and increase half-life of interferon beta. In this study, the effects of R27T and V101F mutations on interferon beta binding to interferon receptors were studied by molecular do...

Background: The refolding of proteins from inclusion bodies is affected by several factors, including solubilization of inclusion bodies by denaturants, removal of the denaturant, and assistance of refolding by small molecule additives. Objectives: The purpose of this study was optimization of recombinant human interferon-b purification in order to achieve higher efficiency, yield, and a produ...

a 46-year-old woman presented with progressive dyspnea and cough. she was a known case of chronic hepatitis c (hcv) treated with pegylated (peg)-interferon. complete pulmonary studies and biopsy were compatible with bronchiolitis oblitrans with organizing pneumonia (boop) secondary to peg-interferon. she discontinued peg-interferon and was given a short course of steroids, after which the condi...

Background: Interferons are some kind of natural cytokines which express in response to a variety of antigens including viral RNA, bacterial products, and tumor proteins. Interferon beta is used in the treatment of autoimmune diseases such as multiple sclerosis. Moreover, this drug inhibits cellular proliferation as well as angiogenesis and as a result, helps to cure cancer. In this research, i...

background: this study was performed to compare the effects of low dose interferon beta-1 (ifn-β-1) (cinnovex, 30 mcg) and high dose ifn-β-1 (rebif, 44 mcg) on the reduction of the number and size of plaques in magnetic resonance imaging (mri) in patients with multiple sclerosis (ms). methods: this historical cohort study, which was performed in 2014 in sanandaj (western part of iran). 43 ms pa...

conclusions treatment with peg ifn α achieved a sustained negativity of hdv rna in about one third of patients. duration of peg ifn α therapy might be prolonged to at least 24 months or more to prevent the occurrence of hepatitis b virus (hbv) relapse encountered six months after completion of the treatment. patients and methods the sample size was based on available patients potentially to be ...

background: brucella is a gram-negative bacterium, causing acute and chronic infection in humans and animals. cell-mediated immunity is the main protective immune response against brucella spp. activation of macrophages by ifn-γ and generation of reactive oxygen intermediates and nitric oxide are the main immunologic mechanisms responsible for control of brucella infection. objective: to invest...

background polymorphisms in the interferon λ (inf λ) genes on chromosome 19 have been associated with clearance of hepatitis c virus (hcv) induced by interferon and ribavirin therapy however there is no such data available for pakistani patients with hcv infection. objectives in this study, the effects of single nucleotide polymorphisms (snps) have been investigated in response to treatment wit...
