Migration of dendritic cells (DC) to the central nervous system (CNS) is a critical event in the pathogenesis of multiple sclerosis (MS). While up until now, research has mainly focused on the transmigration of DC through the blood-brain barrier, experimental evidence points out that also the choroid plexus and meningeal vessels represent important gateways to the CNS, especially in early disease stages. On the other hand, DC can exit the CNS to maintain immunological tolerance to patterns expressed in the CNS, a process that is perturbed in MS...

The posterior visual pathway is commonly affected by multiple sclerosis (MS) pathology that results in measurable clinical and electrophysiological impairment. Due to its highly structured retinotopic mapping, the visual pathway represents an ideal substrate for investigating patho-mechanisms in MS. Therefore, a reliable and robust imaging segmentation method for in-vivo delineation of the optic radiations (OR) is needed. However, diffusion-based tractography approaches, which are typically used for OR segmentation are confounded by the presence of focal white matter lesions...

Citrullination is the post-translational hydrolysis of peptidyl-arginines to form peptidyl-citrulline, a reaction that is catalyzed by the protein arginine deiminases (PADs), a family of calcium-regulated enzymes. Aberrantly increased protein citrullination is associated with a slew of autoimmune diseases (e.g., rheumatoid arthritis (RA), multiple sclerosis, lupus, and ulcerative colitis) and certain cancers. Given the clear link between increased PAD activity and human disease, the PADs are therapeutically relevant targets...

Purinergic receptor P2Y12 (P2Y12 ), a G protein-coupled (GPCR) purinergic receptor, is widely distributed in nervous system and involved in the progression of neurological diseases such as multiple sclerosis and neuropathic pain. The central noradrenergic system actively participates in a number of neurophysiological processes. Nevertheless, whether there is any direct relevance between P2Y12 and noradrenergic signal transduction remains unknown. In the present study, we tested the hypothesis that lack of P2Y12 impaired noradrenergic signal transduction in mouse brain...

Multiple Sclerosis (MS) frequencies are increasing globally affecting populations which traditionally were considered to have a low risk for the disease. MS is common among white Caucasians of northern European ancestry, displaying very high prevalence in Scandinavia and the British Islands, and in the areas where their genetically descendant and migratory groups live: Canada, United States, Australia and New Zealand [1].

Gut microorganisms (microbiota) live in symbiosis with the host and influence human nutrition, metabolism, physiology, and immune development and function. The microbiota prevents pathogen infection to the host, and in turn the host provides a niche for survival. The alteration of gut bacteria composition (dysbiosis) could contribute to the development of immune-mediated diseases by influencing the immune system activation and driving the pro- and anti-inflammatory responses in order to promote or counteract immune reactions...

Though seemingly distinct and autonomous, emerging evidence suggests there is a bidirectional interaction between the intestinal microbiota and the brain. This crosstalk may play a substantial role in neurologic diseases, including anxiety, depression, autism, multiple sclerosis, Parkinson's disease, and, potentially, Alzheimer's disease. Long hypothesized by Metchnikoff and others well over 100 years ago, investigations into the mind-microbe axis is now seeing a rapid resurgence of research. If specific pathways and mechanisms of interaction are understood, it could have broad therapeutic potential, as the microbiome is environmentally acquired and can be modified to promote health...

Purpose: Precise measurements of visual fixation and its instability were recorded during optical coherence tomography (OCT) as a marker of neural network dysfunction in multiple sclerosis (MS), which could be used to monitor disease progression or response to treatment. Methods: A total of 16 MS patients and 26 normal subjects underwent 30 seconds of scanning laser ophthalmoscope (SLO)-based eye tracking during OCT scanning of retinal layer thickness. Study groups consisted of normal eyes, MS eyes without prior optic neuritis (MS wo ON), and MS eyes with prior optic neuritis (MS + ON)...

Golfers with disability are limited in the execution of the full golf swing, but their performance in putting may be comparable because this stroke does not demand significant strength, balance and range of motion. Therefore, the aim of this study was to compare putting performance, kinetic and kinematic consistency between golfers with different disabilities and healthy athletes. The participants consisted of three disabled athletes (perinatal cerebral palsy, multiple sclerosis, below knee lower limb amputee) and three healthy golfers (age 34 ± 4...

Clinical diagnosis of progressive supranuclear palsy (PSP) is sometimes difficult because various phenotypes have been identified. Here, we report a mutation in the bassoon (BSN) gene in a family with PSP-like syndrome. Their clinical features resembled not only those of PSP patients but also those of individuals with multiple system atrophy and Alzheimer's disease. The neuropathological findings showed a novel three + four repeat tauopathy with pallido-luysio-nigral degeneration and hippocampal sclerosis...

BACKGROUND: Multiple sclerosis (MS) carries high morbidity and shortens life span. While there is recent recognition of other US minority populations such as blacks and Hispanics being affected with MS, examination of MS-specific mortality trends by race/ethnicity has been lacking. OBJECTIVE: To investigate MS mortality rates and trends in the United States by sex, age, and race/ethnicity. METHODS: We used the Compressed Mortality data file for 1999-2015 in the Wide-ranging online Data for Epidemiological Research system developed by the Center for Disease Control and Prevention to calculate the age-adjusted (US 2000 standard population) and age-specific MS mortality rate (per 100,000) by race/ethnicity and sex over time...

Vulvar lichen sclerosis (VLS) is a chronic inflammatory skin disorder. Evidence is accumulating that microRNAs (miRNAs) exert crucial roles in initiation and development of a wide range of human diseases. MiR-155-5p has been frequently reported to be implicated in the tumorigenesis and progression of multiple types of cancers, however, its biological role in VLS remains unclear. This study aimed to explore the role of miR-155-5p in VLS and clarify the potential molecular mechanisms involved. In the present study, miR-155-5p was observed to be significantly upregulated in VLS tissues...

BACKGROUND: It is debated whether multiple sclerosis (MS) might result from an immunopathological response toward an active Epstein-Barr virus (EBV) infection brought into the central nervous system (CNS) by immigrating B cells. Based on this model, a relationship should exist between the local immune milieu and EBV infection status in the MS brain. To test this hypothesis, we analyzed expression of viral and cellular genes in brain-infiltrating immune cells. METHODS: Twenty-three postmortem snap-frozen brain tissue blocks from 11 patients with progressive MS were selected based on good RNA quality and prominent immune cell infiltration...

PURPOSE: Structural and physiological abnormalities have been reported in the retina in patients with multiple sclerosis (MS). Retinal oximetry has recently detected changes in retinal oxygen metabolism in Alzheimer's disease and mild cognitive impairment. Our goal was to determine whether oxygen saturation in retinal blood vessels of patients with patients is different from that of a healthy population. METHODS: Oxygen saturation of haemoglobin was measured in retinal blood vessels, using imaging with spectrophotometric noninvasive retinal oximeter...

BACKGROUND: Multiple sclerosis (MS) is most frequent in Caucasian populations. However, studies of MS in other ethnic groups may offer unique insights into genetic and environmental influences on disease, and data on long-term outcomes in these patients is limited. We have investigated clinical features and time to disability milestones in ethnic minority (EM) patients with MS in a UK population and made comparisons to a Caucasian cohort from the same region. METHODS: 1949 MS patients (1866 Caucasian, 83 EM) were identified from a regional disease registry...

Ocrelizumab (Ocrevus), an anti-CD20 monoclonal antibody, has been approved for the treatment of multiple sclerosis. Eculizumab (Soliris) has been approved in several countries for refractory forms of generalized seropositive severe myasthenia gravis. A form of gene therapy, patisiran, has shown positive results in transthyretin familial amyloidosis. In the treatment of headaches, particularly migraines, non-pharmacological approaches have shown some interesting results. The criteria for Lewy body dementia have been revised...

Fumaric acid has an important role in the citric acid cycle. Its esters were first used by a German chemist to treat his own psoriasis, hypothesizing that the disease may be related to disturbances in this very cycle. Meanwhile, the mechanisms underlying its anti-inflammatory efficacy are much better understood. A monosubstance derived from the mix of esters used originally is now being authorized for treating multiple sclerosis, and in 2017 dimethylfumaric acid ester became a globally available option to treat psoriasis...
