multiple sclerosis (ms) is one of the most important autoimmune diseases recognized by demyelination and axonal lesion. it is the most common cause of disability in the young population. various immunomodulatory and immunosuppressive therapies, including different formulations of interferon beta (ifnβ), glatiramer acetate (ga), mitoxantrone, and natalizumab are available for this disease. howev...

BACKGROUND In patients with relapsing-remitting multiple sclerosis (RRMS), subcutaneous (sc) interferon (IFN)β-1a and IFNβ-1b have been shown to reduce relapse rates. A formulation of IFNβ-1a has been produced without fetal bovine serum and without human serum albumin as an excipient (not currently approved for use in the US). The objectives of this study were to evaluate tolerability, injectio...

conclusions this study showed that ifnβ-1a decreased oxidant impacts in ms patients, but had no influence in improving mitochondrial dysfunction. results in the patients group (30 patients), a significant difference was observed in their measured biochemical factors in comparison to the control group (p = 0.001), however, after six months of using ifnβ-1a, only mda was shown in the main (p = 0....

Production of type I interferons, consisting mainly of multiple IFNα subtypes and IFNβ, represents an essential part of the innate immune defense against invading pathogens. While in most situations, namely viral infections, this class of cytokines is indispensable for host survival they mediate a detrimental effect during infection with L. monocytogenes by rendering macrophages insensitive tow...

Many inflammatory diseases, as well as infections, are accompanied by elevation in cellular levels of Reactive Oxygen Species (ROS). Here we report that MPYS, a.k.a. STING, which was recently shown to mediate activation of IFNβ expression during infection, is a ROS sensor. ROS induce intermolecular disulfide bonds formation in MPYS homodimer and inhibit MPYS IFNβ stimulatory activity. Cys-64, -...

BACKGROUND AND PURPOSE Beta-interferons (IFNβ) are the most widely prescribed drugs for patients with multiple sclerosis (MS). However, whether or not treatment with IFNβ can delay secondary progressive MS (SPMS) onset remains unknown. Our aim was to examine the association between IFNβ exposure and SPMS onset in patients with relapsing-remitting MS (RRMS). METHODS A retrospective cohort stud...

Background: Viral infections induce expression of type I interferons (IFNα/β) which result in an antiviral state within cells or animals. However, some viruses, notably influenza viruses (IV), have evolved mechanisms of evasion and blocking of IFN to survive in nature. Swine influenza virus (SIV) can inhibit IFN and as with other IV does it through its NS1 protein, identified as a virulence fac...

OBJECTIVE To compare treatment efficacy and persistence in patients who switched to natalizumab versus those who switched between glatiramer acetate (GA) and interferon-beta (IFNβ) after an on-treatment relapse on IFNβ or GA using propensity score matched real-world datasets. METHODS Patients included were registered in MSBase or the TYSABRI Observational Program (TOP), had relapsed on IFNβ o...

Dr. Andres M. Villa – División Neurología / Hospital General de Agudos “José María Ramos Mejía” / School of Medicine / Buenos Aires University Urquiza 609 (1221) Buenos Aires, Argentina. E-mail: [email protected] Interferon beta (IFNβ) is used in the treatment of multiple sclerosis (MS) because it can reduce relapse rate and lesion formation on MRI and can slow progression of the disease....

Optic neuritis and myelitis are manifestations in both multiple sclerosis (MS) and neuromyelitis optica (NMO). But unlike MS, NMO is characterized by severe optic neuritis, longitudinally extensive and transverse myelitis, and the presence of aquaporin-4 antibody. Since patients with optic neuritis and myelitis have often been diagnosed with "optic-spinal MS (OSMS)" in Asia, it was obscure whet...
