Abstract
AIM To evaluate the efficacy and safety of BCD 054 180 μg and 240 μg administered once every 2 weeks for the treatment of remitting multiple sclerosis compared to placebo and low dose interferon beta-1a (LIB) 30 μg administered once weekly. Results of a 20 week blinded interim analysis from a double blind, comparative, randomised, placebo-controlled clinical study are included. MATERIAL AND METHODS This multinational, multicentre, double blind, comparative, placebo-controlled study enrolled 399 patients with the diagnosis of remitting multiple sclerosis: 114 patients in the sampeginterferon beta 1a and LIB groups each and 57 patients in the placebo group. To ensure the objectivity of data, the study protocol includes a blinded interim analysis to demonstrate the superiority of BCD 054 over placebo based on the number of combined unique active lesions (CUA) on MRI scans after 20 weeks of treatment. RESULTS AND CONCLUSION An integrated analysis of the efficacy, safety, pharmacokinetics, and pharmacodynamics was performed after 20 weeks of study. Mean CUA per scan was lower in the active treatment groups compared to placebo: 0,986±2,046, 0,619±1,055, 0,665±1,165, 1,673±2,376 (groups 1, 2, 3 and placebo group, respectively). The data for CUA per scan demonstrated the superiority of both BCD 054 180 μg and 240 μg over placebo. Patients receiving active treatment had fewer new and/or enlarging lesions after 20 weeks of treatment. The proportion of patients without new T2-weighted lesions was 74,3%, 86,7%, and 78,1% in groups 1, 2, and 3 compared to 64,9% in the placebo group. Manifestations of flu-like syndrome that is expected for interferon treatment were observed with the same incidence in all the active treatment groups. Its severity, duration or the need for symptomatic treatment did not appear to depend on the type of interferon used.

Abstract
Interferon (IFN)-β is a front-line therapy for the treatment of the relapsing-remitting form of multiple sclerosis. However, its immunosuppressive mechanism of function remains incompletely understood. While it has been proposed that IFN-β suppresses the function of inflammatory myelin antigen-reactive T cells by promoting the release of immunomodulatory cytokines such as IL-27 from antigen-presenting cells (APCs), its direct effects on inflammatory CD4+ Th1 cells are less clear. Here, we establish that IFN-β inhibits mouse IFN-γ+ Th1 cell function in the absence of APCs. CD4+ T cells express the type I interferon receptor, and IFN-β can suppress Th1 cell proliferation under APC-free stimulation conditions. IFN-β-treated myelin antigen-specific Th1 cells are impaired in their ability to induce severe experimental autoimmune encephalomyelitis (EAE) upon transfer to lymphocyte-deficient Rag1-/- mice. Polarized Th1 cells downregulate IFN-γ and IL-2, and upregulate the negative regulatory receptor Tim-3, when treated with IFN-β in the absence of APCs. Further, IFN-β treatment of Th1 cells upregulates phosphorylation of Stat1, and downregulates phosphorylation of Stat4. Our data indicate that IFN-γ-producing Th1 cells are directly responsive to IFN-β and point to a novel mechanism of IFN-β-mediated T cell suppression that is independent of APC-derived signals.

Abstract
Multiple sclerosis (MS) is an inflammatory, demyelinating, and neurodegenerative disorder of the CNS. The etiology of MS remains unknown. However, it is well established that immune dysregulation plays a critical role in the neuropathogenesis of this disorder. In this review, we discuss the current hypotheses concerning the complex cellular and molecular interactions involved in the immunopathogenesis of MS. Although CD4 T lymphocytes have long been considered the critical cellular factor in the immunopathology of MS, the role of other cell types has also recently been investigated. It appears that the spatial distribution of CD4 and CD8 cells in MS lesions is distinct. Yet another T-lymphocyte subset, γ/δ T cells, can be detected in very early MS lesions. The prevalent dogma suggests that CD4 helper T (TH) type 1 cells release cytokines and inflammatory mediators that cause tissue damage, while CD4 TH2 cells might be involved in modulation of these effects. However, a mounting body of evidence suggests that additional T-cell subsets, including TH17 cells, CD8 effector T cells, and CD4 CD25 regulatory T cells, also affect disease activity. In addition, clinical and paraclinical data are accumulating on the prominent role of B lymphocytes and other antigen-presenting cells in MS neuropathogenesis. Given these observations, new therapeutic interventions for MS will need to focus on resetting multiple components of the immune system.

Abstract
In summary, MS-related fatigue can be a severe problem causing interference with home and vocational activities. There are multiple factors that can contribute to fatigue in MS, and it is important for the patient, family, and clinician to be aware of potential confounders that may worsen fatigue. Clearer understanding about the etiology of fatigue is necessary. Additional larger, randomized, clinical trials are needed to evaluate etiology, pathophysiology, and both pharmacologic and nonpharmacologic interventions. Given the varying nature of fatigue and the limited evidence that fatigue in MS patients is highly dependent on self-perceived scores, additional research into the effect of psychosocial and psychological interventions is recommended. A multidisciplinary approach to fatigue is encouraged when treatments are considered for maximum benefit.

Abstract
Multiple sclerosis (MS) is an inflammatory, demyelinating, and neurodegenerative disease of the central nervous system of uncertain etiology. There is consensus that a dysregulated immune system plays a critical role in the pathogenesis of MS; therefore, we aim to summarize current hypotheses concerning the complex cellular and molecular interactions involved in the immunopathology of MS. Although CD4+ T lymphocytes have long been implicated in the immunopathology of MS, the role of other T-cell subtypes has been recognized. CD4+ and CD8+ cells have been isolated from different locations within MS lesions and gamma/delta T cells have been isolated from early MS lesions. The prevalent dogma has been that CD4+ TH1 cells release cytokines and mediators of inflammation that may cause tissue damage, although CD4+ TH2 cells may be involved in modulation of these effects. Recent evidence, however, suggests that additional T-cell subsets play a prominent role in MS immunopathology: TH17 cells, CD8+ effector T cells, and CD4+CD25+ regulatory T cells. In addition, laboratory and clinical data are accumulating on the prominent role of B lymphocytes and antigen-presenting cells in MS pathogenesis. On the basis of these observations, new therapeutic approaches for MS will need to focus on resetting multiple components of the immune system.

Abstract
Kelvin and acoustic fields of high-frequency have been employed in the non-invasive investigation of immortalized hypothalamic neurons, in order to assess their response to different concentrations of specific drugs, toxins, a stress-reducing hormone and neurotrophic factors. In an analytical systems biology approach, this work constitutes a first study of living neuron cultures by scanning Kelvin nanoprobe (SKN) and thickness shear mode (TSM) acoustic wave techniques. N-38 hypothalamic mouse neurons were immobilized on the gold electrode of 9 MHz TSM acoustic wave devices and gold-coated slides for study by SKN. The neurons were exposed to the neurochemicals betaseron, forskolin, TCAP, and cerebrolysin. Signals were collected with the TSM in real-time mode, and with the SKN in scanning and real-time modes, as the drugs were applied at biologically significant concentrations. With the TSM, for all drugs, some frequency and resistance shifts were in the same direction, contrary to normal functioning for this type of instrument. Possible mechanisms are presented to explain this behaviour. An oscillatory signal with periodicity of approximately 2 min was observed for some neuron-coated surfaces, where the amplitude of these oscillations was altered upon application of certain neurotrophic factors. These two new techniques present novel and non-invasive electrodeless methods for detecting changes at the cellular level caused by a variety of neuroactive compounds, without killing or destroying the neurons.
