Multiple Sclerosis (MS) is a heterogeneous disease. Although several EMA approved Disease Modifying Treatments including biopharmaceuticals are available, their efficacy is limited and a certain percentage of patients are always non-responsive. Drug Efficacy Monitoring is an important tool to identify these non-responsive patients early on. Currently, Detection of Anti-Drug Antibodies and quantification of Biological Activity are used as methods of efficacy monitoring for Interferon beta (IFNβ) and Natalizumab (NAT) therapies...

BACKGROUND: Adipose-derived mesenchymal stem cells (ASCs) are a promising cell therapy to treat inflammatory and immune-mediated diseases. Development of appropriate pre-clinical animal models is critical to determine safety and attain early efficacy data for the most promising therapeutic candidates. Naturally occurring diseases in cats already serve as valuable models to inform human clinical trials in oncologic, cardiovascular, and genetic diseases. The objective of this study was to complete a comprehensive side-by-side comparison of human and feline ASCs, with an emphasis on their immunomodulatory capacity and transcriptome...

Cytokines of different types play an important role in multiple sclerosis (MS) pathogenesis as mediators and regulators of the immune processes in the central nervous system. The aim of the study was to determine the effect of interferon-beta and glatiramer acetate on serum concentrations of TNF-alpha and IL-17 A and their correlation with the degree of disability in clinically stable patients with relapsing-remitting MS. A cross-sectional, case-control study of 220 patients (68 treatment naïve; 152 treated with interferon-beta or glatiramer acetate) and 99 clinically healthy age-gender-body mass index-matched subjects were performed...

BACKGROUND: Multiple sclerosis (MS) patients treated with interferon beta (IFNβ) are at risk of a declining response to treatment because of the production of IFNβ-neutralizing antibodies (NAbs). The expression of Myxovirus resistance protein A (MxA) mRNA is regarded as a marker of IFNβ bioactivity. AIMS: The aim of this study was to analyze the kinetics of MxA mRNA expression during long-term IFNβ treatment and assess its relationship to NAb production. METHODS: A prospective, observational, open-label, non-randomized study was designed in multiple sclerosis patients starting IFNβ treatment...

Alemtuzumab is a humanized monoclonal antibody targeting the surface molecule CD52, resulting in a rapid depletion of innate and adaptive immune cells. Infection rates in multiple sclerosis (MS) treatment trials were higher in alemtuzumab than in interferon beta-treated patients. We report two MS patients who developed cytomegalovirus disease within 1 month after the first 5-day cycle of alemtuzumab. Upon identification and appropriate treatment of the infection, each recovered completely. Neurologists should be aware of this serious but treatable complication...

The interaction of IFN-β with its receptor IFNAR1 is vital for host-protective anti-viral and anti-proliferative responses, but signaling via this interaction can be detrimental if dysregulated. While it is established that IFNAR1 is an essential component of the IFNAR signaling complex, the key residues underpinning the IFN-β-IFNAR1 interaction are unknown. Guided by the crystal structure of the IFN-β-IFNAR1 complex, we used truncation variants and site directed mutagenesis to investigate domains and residues enabling complexation of IFN-β to IFNAR1...

Cancer-initiating cells (CICs) represent a relatively rare subpopulation of cells endowed with self-renewal, stemness properties, tumorigenicity in immunodeficient mice, and resistance to standard therapies as well as to immunotherapy. Here, we review the biological and immunological characteristics of CICs with special focus on the immunomodulating mechanisms they utilize to escape from immunosurveillance. The recently developed immunotherapeutic strategies have yielded remarkable clinical results in many types of tumors, indicating that indeed a patient's immune system can mount an immune response, which is effective in controlling tumor growth...

BACKGROUND: Hepatitis C virus (HCV) is a single-stranded RNA (ribonucleic acid) virus that has the potential to cause inflammation of the liver. The traditional definition of acute HCV infection is the first six months following infection with the virus. Another commonly used definition of acute HCV infection is the absence of HCV antibody and subsequent seroconversion (presence of HCV antibody in a person who was previously negative for HCV antibody). Approximately 40% to 95% of people with acute HCV infection develop chronic HCV infection, that is, have persistent HCV RNA in their blood...

BACKGROUND: Multiple sclerosis (MS) as an auto-immune disease is an inflammatory, demyelinating disease of the central nervous system. Certain genes have shown to be involved in the initiation of MS but the specific role of some of them, e.g. IFNAR1 has not been identified in certain populations yet. OBJECTIVE: The IFNAR1 as a type I membrane protein shapes one of the two chains of a receptor for interferons alpha and beta. METHODS: To find out how IFNAR1 functions in the Iranian population, the researchers compared the expression level of this gene in relapsing-remitting MS (RR-MS) samples with normal individuals...

Quinolinic acid, a macrophage/microglia-derived excitotoxin fulfills a plethora of functions such as neurotoxin, gliotoxin, and proinflammatory mediator, and it alters the integrity and cohesion of the blood-brain barrier in several pathophysiological states. Beta-trace protein (BTP), a monomeric glycoprotein, is known to indicate cerebrospinal fluid leakage. Thus, the prior aim of this study was to investigate whether BTP might non-invasively indicate quinolinic acid-induced impaired blood-brain barrier integrity...

BACKGROUND: Autoimmune hepatitis (AIH) is a rare and chronic inflammatory disorder associated with extrahepatic autoimmune diseases, including, infrequently, multiple sclerosis (MS). Short Reports: We report five cases of MS and AIH association. One patient developed AIH while under interferon beta-1b and the remaining while off disease-modifying therapy, although after methylprednisolone bolus in three. All presented a liver biopsy compatible with AIH. Hepatitis resolution was achieved with immunosuppressive treatment, but one patient died after a fulminant hepatitis requiring liver transplant...

This study detected the effects of maternal carbamazepine (CBZ) on the fetal neuroendocrine-cytokines axis. 25 or 50mg/kg of CBZ was intraperitoneally administrated to pregnant rats from gestation day (GD) 1 to 20. In dams and their fetuses, there was an elevation in the values of serum thyrotropin (TSH) which was accompanied by a decrease in the values of serum thyroxine (T4) and triiodothyronine (T3) at GD 20 due to both maternal administrations of CBZ compared to the control group. Also, both administrations had undesirable impacts on the maternal body weight gain, fetal body weight, survival of dams and fetuses, food consumption, and litter weight as compared to the corresponding control group...
