Experimental autoimmune encephalomyelitis (EAE), the most common model for multiple sclerosis, is characterized by inflammatory cell infiltration into the central nervous system and demyelination. Previous studies have demonstrated that administration of some polyphenols may reduce the neurological alterations of EAE. In this work, we show that ellagic acid, a polyphenolic compound, is beneficial in EAE, most likely through stimulation of ceramide biosynthesis within the brain. EAE was induced in Lewis rats by injection of guinea-pig spinal cord tissue along with Freund's complete adjuvant containing Mycobacterium tuberculosis...

BACKGROUND: Multiple sclerosis (MS) is a non-curable chronic inflammatory disease of the central nervous system that affects more than 2 million people worldwide. MS-related symptoms impact negatively on the quality of life of persons with MS, who need to be active in the management of their health. mHealth apps could support these patient groups by offering useful tools, providing reliable information, and monitoring symptoms. A previous study from this group identified needs, barriers, and facilitators for the use of mHealth solutions among persons with MS...

BACKGROUND: The influence of personality on health-related quality of life in patients with multiple sclerosis has been the focus of previous studies showing that introversion and neuroticism were related with reduced health related quality of life. However, no data exist on the impact of temperament on quality of life in this patient group. METHODS: Between April 2014 and March 2016 139 multiple sclerosis patients were recruited from a specialized outpatient clinic of the general hospital of Vienna...

Multiple sclerosis (MS) is a chronic central nervous system inflammatory disease of autoimmune etiology, mediated by activated T cells with evolving evidence of a significant contribution from B cells and cells of the innate immune system. The disease is thought to be due to a complex interaction between different genetic and environmental factors. The prevalence of MS is rising all over the world, due on one hand to earlier diagnosis and prolonged survival, and on the other to a true increase in incidence of the disease...

"Stem cell tourism" is defined as the unethical practice of offering unproven cellular preparations to patients suffering from various medical conditions. This phenomenon is rising in the field of neurology as patients are requesting information and opportunities for treatment with stem cells for incurable conditions such as multiple sclerosis and amyotrophic lateral sclerosis, despite their clinical research and experimental designation. Here, we review the recent trends in "stem cell tourism" in both the United States and abroad, and discuss the recent reports of neurological complications from these activities...

In this paper, we will present a case of organ donation after active euthanasia (ODE) in The Netherlands from a patient who had his life ended at his explicit and voluntary request. The form of ODE we describe here concerns patients who are not unconscious and on life support, but who are conscious and want to have their life ended because of their hopeless and unbearable suffering, for instance due to a terminal illness such as Amyotrophic Lateral Sclerosis (ALS) or Multiple Sclerosis (MS). This form of ODE is of course only possible in jurisdictions where euthanasia is allowed...

BACKGROUND: Modifiable risk factors such as smoking and sedentary lifestyle adversely affect multiple sclerosis (MS) progression. Few multimodal behavioural interventions have been conducted for people with MS, and follow-up beyond 1 year is rare for lifestyle interventions. This study assessed adoption and adherence to healthy lifestyle behaviours and health outcomes 3 years after a lifestyle modification intervention, using generalized estimating equation models to account for within-participant correlation over time...

Leukocyte entry into the CNS is a crucial step in the development of multiple sclerosis and its animal model experimental autoimmune encephalomyelitis (EAE). Adhesion molecules mediating the docking of leukocytes to the endothelium of the blood-brain barrier (BBB) represent valuable targets for interference with the disease. However, little is known about the adhesion and signaling mechanisms in endothelial cells that mediate the diapedesis through the BBB. Here, we show that conditional Tie-2-Cre driven gene inactivation of CD99L2 inhibits leukocyte entry into the CNS during active MOG35-55 -induced EAE and alleviates severity of the disease...

Microglia, the mononuclear phagocytes of the central nervous system (CNS), are important for the maintenance of CNS homeostasis, but also critically contribute to CNS pathology. Here we demonstrate that the nuclear factor kappa B (NF-κB) regulatory protein A20 is crucial in regulating microglia activation during CNS homeostasis and pathology. In mice, deletion of A20 in microglia increases microglial cell number and affects microglial regulation of neuronal synaptic function. Administration of a sublethal dose of lipopolysaccharide induces massive microglia activation, neuroinflammation, and lethality in mice with microglia-confined A20 deficiency...

The human autoimmune disease-associated HLA alleles HLA-DR2b (DRB1*1501) and HLA-DR4 (DRB1*0401) are strongly linked to increased susceptibility for multiple sclerosis (MS) and rheumatoid arthritis (RA), respectively. The underlying mechanisms are not fully understood, but these MHC alleles may shape the repertoire of pathogenic T cells via central tolerance. The transcription factor autoimmune regulator (AIRE) promotes central T cell tolerance via ectopic expression of tissue-specific antigens (TSAs). Aire deficiency in humans causes autoimmune polyendocrinopathy syndrome type 1 (APS1), and Aire knockout mice (Aire-/- ) develop spontaneous autoimmune pathology characterized by multi-organ lymphocytic infiltrates...

BACKGROUND: Neuroinflammatory diseases that affect spinal cord or associated spinal nerves represent challenging conditions for management in current medicine because of their complex pathology, poor prognosis, and high morbidity, which strikingly reduces the quality of life of patients. In this sense, a better understanding of the cellular and molecular mechanisms of spinal cord neuroinflammation might contribute to the development of novel therapies. Oligodendrocytes have unique and vital biological properties in central nervous system (CNS) homeostasis and physiology...

Due to their trophic and immunoregulatory characteristics mesenchymal stem cells (MSCs) have tremendous potential for use in a variety of clinical applications. Challenges in MSCs' clinical applications include low survival of transplanted cells and low grafting efficiency requiring use of a high number of MSCs to achieve therapeutic benefits. Accordingly, new approaches are urgently needed in order to overcome these limitations. Recent evidence indicates that modulation of autophagy in MSCs prior to their transplantation enhances survival and viability of engrafted MSCs and promotes their pro-angiogenic and immunomodulatory characteristics...

Sjogren's syndrome (SS) is an autoimmune connective tissue disorder (CTD) which principally affects the lacrimal and salivary glands. Although SS is one of the three most common autoimmune CTDs alongside systemic lupus erythematosus (SLE) and progressive systemic sclerosis, it is the least researched CTD overall. SS poses a particular diagnostic challenge because it shares multiple clinical and immunologic features with other CTDs. However, there are some characteristic cutaneous clinical features that can precede the well-known sicca symptoms by years...

PURPOSE: In clinical practice, acute optic neuritis (ON) associated with the development of neuromyelitis optica (NMO) after the first attack is often indistinguishable from that associated with multiple sclerosis (MS). We aimed to determine the optimal combination of features derived from conventional magnetic resonance imaging (MRI) and diffusion-weighted imaging using readout-segmented echo-planar imaging (RESOLVE-DWI) for the differentiation of these conditions. MATERIALS AND METHODS: Orbital conventional MRI and RESOLVE-DWI were performed using a 3...
