Immunotherapy with Interferon-beta (IFN beta) results in remarkably beneficial effects in patients with relapsing-remitting multiple sclerosis (MS), although the mechanisms by which it exerts these beneficial effects remain poorly understood. An investigation was made of the effects of IFN beta on pro-inflammatory and anti-inflammatory cytokine production in peripheral blood cells in MS patients, both untreated and those undergoing immunotherapy. as well as in healthy controls. Results show a significant increase in the production of pro-inflammatory cytokines such as TNF alpha, IFN gamma and IL-12 in the plasma and in the supernatant of leukocyte cultures from MS patients with the untreated disease; IFN beta administration significantly reduced the levels of TNF alpha and IFN gamma, with no changes in the level of IL-12. The Interferon-beta therapy also led to a significant increase in the production of IL-10, as well as a slight increase in that of TGF beta. The reduction in pro-inflammatory ...
Blurred vision, weak limbs, tingling sensations, unsteadiness and fatigue are the symptoms of one of the most common diseases of the central nervous system, the multiple sclerosis (MS). It is estimated that MS currently affects over 2,500,000 people worldwide. There is new hope for MS patients: The protein Interferon-beta, which is produced in bacterial or mammalian cells by genetic engineering, is being used successfully in the treatment of multiple sclerosis. However, the very high hydrophobicity and thus poor solubility of Interferon-beta, proves to be problematic for the production and clinical efficacy of recombinant human Interferon-beta.. In order to solve this problem, scientists from the German Fraunhofer Institute for Interfacial Engineering and Biotechnology (Fraunhofer-Institut für Grenzflächen- und Bioverfahrenstechnik IGB) designed variants of recombinant human Interferon-beta whose solubility is improved. They replaced the hydrophobic portions of the molecule by soluble ones. ...
Human IFN Beta ELISA kit with LLOQ 1.2 pg/ml for quantitation of IFN-beta in normal human serum and plasma, autoimmune disease sera and plasma, and cell culture media
Multiple sclerosis (MS) is an inflammatory demyelinating disease affecting young adults (with a peak of onset between the ages of 20 and 40 years). In 80-90\% of cases, it is characterized by an early relapsing-remitting (RR) inflammatory phase, followed by a secondary progressive course in which disability progressively accumulates. Interferon-beta (IFNbeta) therapies represent the first-line treatment of RRMS. There are three IFNbeta formulations currently licensed for RRMS. Two are formulations of INFbeta-1a, one administered at a dosage of 30 mug intramuscularly weekly (Avonex(R)) and the other administered at a dosage of 22 or 44 microg subcutaneously (SC) three times a week (Rebif(R) 22 and 44). The third is a formulation of IFNbeta-1b, administered at a dosage of 250 microg SC every other day (Betaseron(R)). These treatments reduce the frequency of acute relapses and, to a lesser extent, disability progression. However, when starting an IFNbeta therapy, a treatment discontinuation rate ...
PURPOSE: To study the effect of oxidation on the structure of recombinant human interferon beta-1a (rhIFNbeta-1a) and its immunogenicity in wild-type and immune-tolerant transgenic mice. METHODS: Untreated rhIFNbeta-1a was degraded by metal-catalyzed oxidation, H(2)O(2)-mediated oxidation, and guanidine-mediated unfolding/refolding. Four rhIFNbeta-1a preparations with different levels of oxidation and aggregation were injected intraperitoneally in mice 15x during 3 weeks. Both binding and neutralizing antibodies were measured. RESULTS: All rhIFNbeta-1a preparations contained substantial amounts of aggregates. Metal-catalyzed oxidized rhIFNbeta-1a contained high levels of covalent aggregates as compared with untreated rhIFNbeta-1a. H(2)O(2)-treated rhIFNbeta-1a showed an increase in oligomer and unrecovered protein content by HP-SEC; RP-HPLC revealed protein oxidation. Guanidine-treated rhIFNbeta-1a mostly consisted of dimers and oligomers and some non-covalent aggregates smaller in size than ...
Like many other therapeutic proteins, recombinant human interferon beta (rhIFN-β) elicits undesirable immune responses. rhIFN-β-treated multiple sclerosis patients may form binding antibodies and neutralizing antibodies (NAbs), with the latter being responsible for inhibition of the therapeutic effect of the protein. The incidence of binding antibodies and NAbs against rhIFN-β as well as the titer and persistence of NAbs differ among the marketed products. The proportion of patients forming antibodies against rhIFN-β-1b is higher than that against rhIFN-β-1a, which is likely explained by the differences in protein structure and aggregation behavior between the 2 types of rhIFN-β. Here, we summarize the different factors influencing the immunogenicity of rhIFN-β in patients with multiple sclerosis and discuss the role played by rhIFN-β aggregates.. ...
BENEFIT is a multi-center trial conducted at 98 sites in 20 countries and included patients presenting with a first clinical episode suggestive of MS and typical MRI findings. The primary outcome measures are time to diagnosis of CDMS (Clinically Definite MS), time to confirmed EDSS (Expanded Disability Status Scale) progression and patient reported Quality of Life outcomes (FAMS-TOI). A total of 468 patients were randomized to receive either 250 micrograms of interferon beta-1b (Betaferon®) every other day or placebo as a subcutaneous injection in a double-blind fashion. The placebo-controlled treatment period lasted up to 24 months or up to the time when patients experienced a second attack and were diagnosed with clinically definite MS. All study participants were then invited to participate in a follow-up study with Betaferon® to prospectively assess the impact of such early versus delayed treatment with Betaferon® on the long-term course of the disease for a total observation time of ...
Interferon beta-1b is a cytokine in the interferon family used to treat the relapsing-remitting and secondary-progressive forms of multiple sclerosis (MS). It is approved for use after the first MS event. It is administered by sub-cutaneous injection and has been advertised as a way to slow the advance of the affliction as well as reduce the frequency of attacks. Closely related is interferon beta 1a, also indicated for MS, and with a very similar drug profile. The assertion that interferon beta in either form can slow the advance of disability in multiple sclerosis is still unproven. Interferon beta balances the expression of pro- and anti-inflammatory agents in the brain, and reduces the number of inflammatory cells that cross the blood brain barrier. Overall, therapy with interferon beta leads to a reduction of neuron inflammation. Moreover, it is also thought to increase the production of nerve growth factor and consequently improve neuronal survival. Interferon beta-1b is available only in ...

METHODS: The analysis included two large, independent datasets of RRMSers who were treated with interferons that included 4-year follow-up data. The first dataset (training set) comprised of 373 RRMSers from a randomized clinical trial of subcutaneous interferon beta-1a. The second (validation set) included an observational cohort of 222 RRMSers treated with different interferons. The new scoring system, a modified version of that previously proposed by Rio et al., was first tested on the training set, then validated using the validation set. The association between disability progression and risk group, as defined by the score, was evaluated by Kaplan Meier survival curves and Cox regression, and quantified by hazard ratios (HRs). ...

Conflicting reports exist regarding the requirement for virus replication in interferon (IFN) induction by paramyxoviruses. Our previous work has demonstrated that pathogen-associated molecular patterns capable of activating the IFN-induction cascade are not normally generated during virus replication, but are associated instead with the presence of defective interfering (DI) viruses. We demonstrate here that DIs of paramyxoviruses, including parainfluenza virus 5, mumps virus and Sendai virus, can activate the IFN-induction cascade and the IFN-β promoter in the absence of virus protein synthesis. As virus protein synthesis is an absolute requirement for paramyxovirus genome replication, our results indicate that these DI viruses do not require replication to activate the IFN-induction cascade.
This protein specifically binds to the DNA sequence 5-GGGACTTTCC-3 which is found in the enhancer elements of numerous viral promoters such as those of SV40, CMV, or HIV1. In addition, related sequences are found in the enhancer elements of a number of cellular promoters, including those of the class I MHC, interleukin-2 receptor, somatostatin receptor II, and interferon-beta genes. It may act in T-cell activation.
Binding of interferon beta-1b to these receptors induces the expression of a number of substances which are considered as mediators of biological effects of interferon beta-1b. The content of some of these substances were determined in serum and fractions of blood cells of patients treated with interferon beta-1b. Interferon beta-1b decreases the binding capacity and expression of receptors of gamma interferon enhances their dissolution. The drug increases the suppressive activity of peripheral blood mononuclear cells ...

However, both local and systemic antibodies attempt to block the rep-lication and spread of viruses, either circulating or being shed from a cell that has been infected and killed. IgG is the most prevalent anti-body of the immunoglobulin system and is a potent opsonizing agent. The complement system of serum proteins is activated by IgM and later by IgG. They opsonize target cells for the phagocytes, which are then bound by IgM or IgG, and this is the classical pathway. Cells synthesize interferon when infected by virus; it is secreted into extracellular fluid and binds to adjacent cells. Interferon-alpha is de-rived from lymphocytes and interferon-beta from fibroblasts and other cell types. The IFNs acton certain cell genes that either catalyse or retard factors responsible for protein synthesis, which in turn re-duces mRNA translation, while another factor results in the degrada-tion of host and viral mRNA. The total result is to establish a sort of cordon of uninfectable cells around the ...

The goal of this study is to evaluate the safety, tolerability and effectiveness of oral cladribine when taken in combination with Interferon-beta (IFN-beta) therapy for the treatment of multiple sclerosis (MS).. This study will randomize around 200 subjects from approximately 50 sites located world-wide, who have experienced at least one relapse while taking IFN-beta therapy within 48 weeks prior to Screening, irrespective of disability progression. Secondary progressive multiple sclerosis (SPMS) subjects, who are still experiencing relapses, and subjects who have received disease modifying drugs (DMDs), other than IFN-beta therapy, during their MS treatment history, but are currently on IFN-beta therapy and have experienced active MS symptoms (at least 1 relapse) during the 48 weeks prior to Screening, may also be enrolled.. Subjects will be randomized in a 2:1 fashion to receive up to 4 cycles of oral cladribine or matching placebo in combination with IFN-beta therapy. Subjects who complete ...
Multiple sclerosis is a neurological disease caused by discrete plaques of demyelination at sites throughout the central nervous system caused by a T-Cell mediated immune response with an unknown trigger. It has a lifetime risk of 1:1000 in the UK, and is twice as prevalent in females with the typical onset being between 20 and 40 years of age, namely the childbearing ages.. There are many disease-modifying therapies used to treat Multiple Sclerosis. However, immunomodulatory and immunosuppressive drugs used at any stage of pregnancy may affect fetus formation and/or development.. Interferons are a group of naturally occurring macromolecules with antiviral, antiproliferative and immunomodulatory properties, and interferon beta is currently the most widely used therapy for multiple sclerosis. However, limited data in primates suggests that interferon beta may be abortifacient. Due to this and due to lack of experience with drug safety, it is usually suggested that either treatment is suspended ...
Interferon beta-1a (also interferon beta 1-alpha) is a cytokine in the interferon family used to treat multiple sclerosis (MS). It is produced by mammalian cells, while interferon beta-1b is produced in modified E. coli. Some claims have been made that Interferons produce about an 18-38% reduction in the rate of MS relapses. Interferon beta has not been shown to slow the advance of disability. Interferons are not a cure for MS (there is no known cure); the claim is that interferons may slow the progress of the disease if started early and continued for the duration of the disease. The earliest clinical presentation of relapsing-remitting multiple sclerosis is the clinically isolated syndrome (CIS), that is, a single attack of a single symptom. During a CIS, there is a subacute attack suggestive of demyelination which should be included in the spectrum of MS phenotypes. Treatment with interferons after an initial attack decreases the risk of developing clinical definite MS. Medications are ...
Probable ATP Dependent RNA Helicase DDX58 (DEAD Box Protein 58 or RIG I Like Receptor 1 or Retinoic Acid Inducible Gene 1 Protein or DDX58 or EC 3.6.4.13) - Pipeline
Type I interferon (IFN) is an important host defense cytokine against intracellular pathogens, mainly viruses. In assessing IFN production in response to group B streptococcus (GBS), we find that IFN-beta was produced by macrophages upon stimulation with both heat-killed and live GBS. Exposure of macrophages to heat-killed GBS activated a Toll-like receptor (TLR)-dependent pathway, whereas live GBS activated a TLR/NOD/RIG-like receptor (RLR)-independent pathway. This latter pathway required bacterial phagocytosis, proteolytic bacterial degradation, and phagolysosomal membrane destruction by GBS pore-forming toxins, leading to the release of bacterial DNA into the cytosol. GBS DNA in the cytosol induced IFN-beta production via a pathway dependent on the activation of the serine-threonine kinase TBK1 and phosphorylation of the transcription factor IRF3. Thus, activation of IFN-alpha/-beta production during infection with GBS, commonly considered an extracellular pathogen, appears to result from the
Cytosolic viral RNA recognition by the helicases RIG-I and MDA5 is considered the major pathway for IFN-alpha/beta induction in response to RNA viruses. However, other cytoplasmic RNA sensors, including the double-stranded RNA-binding protein kinase R (PKR), have been implicated in IFN-alpha/beta production, although their relative contribution and mechanism have been unclear. Using cells expressing nonfunctional PKR or reduced levels of kinase, we show that PKR is required for production of IFN-alpha/beta proteins in response to a subset of RNA viruses including encephalomyocarditis, Theilers murine encephalomyelitis, and Semliki Forest virus, but not influenza or Sendai virus. Surprisingly, although IFN-alpha/beta mRNA induction is largely normal in PKR-deficient cells, much of that mRNA lacks the poly(A) tail, indicating that its integrity is compromised. Our results suggest that PKR plays a nonredundant role in IFN-alpha/beta production in response to some but not all viruses, in part by regulating
Subcutaneous interferon beta-1a is an effective treatment for relapsing/remitting MS in terms of relapse rate, defined disability, and all MRI outcome measures in a dose-related manner, and it is well tolerated. Longer-term benefits may become clearer with further follow-up and investigation.

The detection of intracellular microbial DNA is critical to appropriate innate immune responses; however, knowledge of how such DNA is sensed is limited. Here we identify IFI16, a PYHIN protein, as an intracellular DNA sensor that mediates the induction of interferon-beta (IFN-beta). IFI16 directly associated with IFN-beta-inducing viral DNA motifs. STING, a critical mediator of IFN-beta responses to DNA, was recruited to IFI16 after DNA stimulation. Lowering the expression of IFI16 or its mouse ortholog p204 by RNA-mediated interference inhibited gene induction and activation of the transcription factors IRF3 and NF-kappa B induced by DNA and herpes simplex virus type 1 (HSV-1). IFI16 (p204) is the first PYHIN protein to our knowledge shown to be involved in IFN-beta induction. Thus, the PYHIN proteins IFI16 and AIM2 form a new family of innate DNA sensors we call AIM2-like receptors (ALRs ...
Little is known about whether tolerability and adherence to treatment can be influenced by weather and temperature conditions.

Alemtuzumab is a humanized monoclonal antibody directed against CD52 to deplete circulating T and B lymphocytes; lymphocyte depletion is followed by a distinctive pattern of T- and B-cell repopulation, changing the balance of the immune system. This review reports the efficacy and safety findings of the phase 2 CAMMS223 trial and the phase 3 CARE-MS I and II trials investigating alemtuzumab for the treatment of active relapsing-remitting MS. Alemtuzumab, administered intravenously, was shown to improve relapse rate versus subcutaneous interferon beta-1a in patients who were treatment-naive (CAMMS223 and CARE-MS I) or had relapsed on prior therapy (CARE-MS II), and to reduce sustained accumulation of disability (CAMMS223 and CARE-MS II ...

Bacterial and viral RNA are potent stimulators of the innate immune system, leading to immune cell activation and type I IFN production (Takeuchi and Akira, 2010). Generally, RNA recognition takes place in the endosome or cytoplasm and is mediated by Toll-like receptors (TLRs) and retinoic acid inducible gene I (RIG-I)-like helicases, respectively. In more detail, TLR3 recognizes double-stranded viral RNA and mRNA, whereas TLR7 and TLR8 sense viral or bacterial single-stranded RNA and short interfering RNA (siRNA; Blasius and Beutler, 2010). In contrast, cytoplasmic detection of viral and bacterial RNA is mediated by the RNA helicases RIG-I and MDA5 (melanoma differentiation-associated gene 5; Kato et al., 2006; Monroe et al., 2009).. Of note, RNA modifications in ribosomal RNA and transfer RNA (tRNA) such as 2′-O-methylation, base methylation (e.g., m5C, m6A, and m5U), and the occurrence of pseudouridine negatively modify the immunostimulatory potential of synthetic RNA (Karikó et al., ...

BACKGROUND: Natalizumab (NTZ) discontinuation leads to multiple sclerosis reactivation.The objective of this study is to compare disease activity in MS patients who continued on NTZ treatment to those who were switched to subcutaneous interferon 1b (IFNB) treatment. METHODS: 1-year randomized, rater-blinded, parallel-group, pilot study (ClinicalTrial.gov ID: NCT01144052). Relapsing remitting MS patients on NTZ for ≥12 months who had been free of disease activity on this therapy (no relapses and disability progression for ≥6 months, no gadolinium-enhancing lesions on baseline MRI) were randomized to NTZ or IFNB. Primary endpoint was time to first on-study relapse. Additional clinical, MRI and safety parameters were assessed. Analysis was based on intention to treat. RESULTS: 19 patients (NTZ n=10; IFNB n=9) with similar baseline characteristics were included. 78% of IFNB treated patients remained relapse free (NTZ group: 100%), and 25% remained free of new T2 lesions (NTZ group: 62.5%). While time to
FINDINGS: Patients were treated between Aug 1, 1994, and June 30, 2016. The cohorts consisted of 189 patients given alemtuzumab, 2155 patients given interferon beta, 828 patients given fingolimod, and 1160 patients given natalizumab. Alemtuzumab was associated with a lower annualised relapse rate than interferon beta (0·19 [95% CI 0·14-0·23] vs 0·53 [0·46-0·61], p,0·0001) and fingolimod (0·15 [0·10-0·20] vs 0·34 [0·26-0·41], p,0·0001), and was associated with a similar annualised relapse rate as natalizumab (0·20 [0·14-0·26] vs 0·19 [0·15-0·23], p=0·78). For the disability outcomes, alemtuzumab was associated with similar probabilities of disability accumulation as interferon beta (hazard ratio [HR] 0·66 [95% CI 0·36-1·22], p=0·37), fingolimod (1·27 [0·60-2·70], p=0·67), and natalizumab (0·81 [0·47-1·39], p=0·60). Alemtuzumab was associated with similar probabilities of disability improvement as interferon beta (0·98 [0·65-1·49], p=0·93) and fingolimod (0·50 ...
Therapeutic interferon beta is the first line treatment of relapsing remitting Multiple Sclerosis. However, despite their success in improving patient wellbeing, all IFNβ products encounter a significant problem: immunogenicity. In some patients, IFNβ products induce the formation of antidrug antibodies that undermine treatment efficacy and may even lead to treatment ... read more failure. These patients not only have a substantial health risk due to failing treatment, but are being treated with expensive products that no longer work. We thus urgently need to lower immunogenicity of therapeutic interferon beta products. In this thesis, IFNβ-1b, the most immunogenic IFNβ product, was studied. The first step in lowering immunogenicity is to understand why a product is immunogenic. Here, there are two possibilities: (1) IFNβ-1b is immunogenic because of epitopes, the foreign peptide sequences that induce a classical immune response, and (2) immunogenicity is caused by aggregates present in the ...
Recognition of invading viruses by the host is elicited by cellular sensors which trigger signaling cascades that lead to type I interferon (IFN) gene expression. Retinoic acid-inducible gene I (RIG-I) has emerged as a key receptor for the detection of viral RNA in the cytosol, inducing IFN-mediated innate immune responses to limit viral replication through its interaction with MAVS (also called IPS-1, CARDIF, or VISA). Upon the recognition of viral RNA, the Lys-172 residue of RIG-I undergoes ubiquitination induced by tripartite motif protein 25 (TRIM25), an essential protein for antiviral signal transduction. Here we demonstrate that phosphorylation represents another regulatory mechanism for RIG-I-mediated antiviral activity. Using protein purification and mass spectrometry analysis, we identified three phosphorylation sites in the amino-terminal caspase recruitment domains (CARDs) of RIG-I. One of these residues, Thr-170, is located in close proximity to Lys-172, and we speculated that its ...
I believe with all my heart, that if I continue the traditional treatments I am currently using, it will only slightly deter the course of the MS. When I was first diagnosed with Multiple Sclerosis, I started on an Interferon beta-1a medication known as Rebif. I was given Rebif injections three times a week however, one of the largely diagnosed side effects of Rebif is depression. I would sink into deep fits of depression; the drug changed who I was as a person. I hated the feeling of being down all the time, and I felt uncomfortable when my doctor would prescribe anti-depressants. I used Rebif for nine months. During those nine months, I had numerous exacerbations. I was scared for my future, and I knew the Rebif was not doing what it was suppose to be doing. After my doctor agreed that the Rebif was not working as we had hoped it would, I was put on another Interferon beta-1a medication. This medication was Avonex, the number one prescribed MS therapy. Once again, after being on this treatment ...

A newspaper considered very friendly to the government did ask some questions and the answers are revealing: 1. Economists will reach the same conclusions when they look at the economic indicators: declining Gross Fixed Capital Formation (GFCF), your girlfriends and male buddies, have your back unconditionally, There are a number of areas in this bill that,with persons on interferon-beta having nearly three-times as much vitamin D from similar amounts of sun exposure to those not taking interferon-beta, Quami Ekta Dal workers have started campaigning for Kol in the constituency, Lt Gen Hanut Singh (retd) has passed away in Dehradun. It seems the Golmaal Again actor is making most of his time with the munchkin after back to back promotional events of his recent release.

Plays an essential role in transcription initiation and cap-stealing mechanism, in which cellular capped pre-mRNAs are used to generate primers for viral transcription. Recognizes and binds the 7-methylguanosine-containing cap of the target pre-RNA which is subsequently cleaved after 10-13 nucleotides by the viral protein PA. Plays a role in the initiation of the viral genome replication and modulates the activity of the ribonucleoprotein (RNP) complex. In addition, participates in the inhibition of type I interferon induction through interaction with and inhibition of the host mitochondrial antiviral signaling protein MAVS.
For some infections, such as those caused by some viruses, fever is a normal part of the infection fighting process. But what induces the fever? One possibility is a protein called RIG-1 (retinoic acid inducible gene protein one). This protein is a helicase which recognizes double stranded RNA (dsRNA). dsRNA is often found in viruses but not in uninfected animal cells. This ensures that RIG-1 is only active in infected cells. ...
The research team analyzed urine samples from over 400 participants who took part in the Betaferon/Betaseron in Newly Emerging Multiple Sclerosis for Initial Treatment (BENEFIT)clinical trial. The 5-year trial was designed to evaluate if interferon beta-1b compared to placebo could reduce conversion to MS in people who had their first clinical event suggestive of MS, called clinically isolated syndrome (CIS). Trial participants provided urine samples during clinic visits that took place at the start of the trial (baseline), every 3 months until month 12, and then every 6 months until the end of the trial, which were later analyzed to determine sodium intake levels. As sodium intake varies throughout the day, the best measure is to obtain multiple urine samples over a 24-hour period. As urine samples were not taken for a full 24 hours in the BENEFIT trial, 24-hour sodium excretion value was estimated using a validated formula that takes into consideration the amount of sodium in the urine, the ...
The ability of a cell to combat an intracellular pathogen requires a mechanism to recognize the threat and elicit a transcriptional response against it. In the context of virus infection, the cell must take measures to inhibit viral replication, meanwhile, convey warning signals to neighboring cells of the imminent threat. This immune response is predominantly mediated by the production of cytokines, notably, interferon beta (IFNβ). IFNβ signaling results in the transcriptional induction of over one hundred antiviral gene products whose timely expression renders infected cells more capable of inhibiting virus replication, while providing the uninfected cells with the reinforcements to generate a less permissive cellular environment. Induction of IFNβ and many aspects of the antiviral response pivot on the function of the IKK and IKK-related kinases. Despite sharing high levels of homology and some degree of functional redundancy, the classic IKK kinases: IKKα and IKKβ, and the IKK-related kinases:
A mathematical model finds that antiviral cytokines secondarily control herpes simplex virus 2 reactivation when T cell numbers are insufficient to lyse infected cells directly.
