Orphan nuclear receptor Nurr1 plays important roles in the progression of various diseases, including Parkinson's disease, neuroinflammation, Alzheimer's disease, and multiple sclerosis. It can recognize DNA as a monomer or heterodimer with retinoid X receptor α (RXRα). But the molecular mechanism of its transcriptional activity regulation is still largely unknown. Here we obtained a crystal structure of monomer Nurr1 (DNA- and ligand-binding domains, DBD and LBD) bound to NGFI-B response element...

Dimethyl fumarate (DMF) is a first-line prodrug for the treatment of relapsing-remitting multiple sclerosis (RRMS) that is completely metabolized to monomethyl fumarate (MMF), the active metabolite, before reaching the systemic circulation. Its metabolism has been proposed to be due to ubiquitous esterases in the intestines and other tissues, but the specific enzymes involved are unknown. We hypothesized based on its structure and extensive presystemic metabolism that DMF would be a carboxylesterase substrate subject to interaction with alcohol...

Somatic mutations have a central role in cancer, but there are also a few rare autoimmune diseases in which somatic mutations play a major role. We have recently shown that nonsynonymous somatic mutations with low allele fractions are preferentially detectable in CD8+ cells and that the STAT3 gene is a promising target for screening. Here, we analyzed somatic mutations in the STAT3 SH2 domain in peripheral blood CD8+ cells in a set of 94 multiple sclerosis (MS) patients and 99 matched controls. PCR amplicons targeting the exons 20 and 21 of STAT3 were prepared and sequenced using the Illumina MiSeq instrument with 2x300bp reads...

Multiple sclerosis (MS) is a debilitating, demyelinating disease of the central nervous system, with manifestations ranging from numbness and blindness to paralysis. Typical MS is a slowly progressive demyelinating disease, causing significant morbidity spanning over many years. In contrast, "Marburg's disease" is a rare variant of MS which demonstrates a malignant monophasic disease progression leading to death within weeks to months. We present a rapidly fatal demyelinating disease with the clinicopathological findings on par with the handful of reported cases of "Marburg's disease" in the literature...

Dealing with patients with both multiple sclerosis (MS) and inflammatory rheumatic disorders (IRD) is not uncommon for a rheumatologist, as there is a statistical association between spondyloarthritis and MS. As several central nervous system demyelinating events have been reported in patients treated with TNFi, the pre-existing demyelinating disease was considered a contraindication for TNFi. However, this contraindication is mainly based on a randomized controlled trial in MS and not on large epidemiologic studies...

BACKGROUND: Multiple sclerosis (MS) is a neurological disorder marked by accumulating immune-mediated damage to the central nervous system. The dysregulated immune system in MS combined with immune effects of disease-modifying therapies (DMTs) used in MS treatment could alter responses to infections, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19). Most of the literature on immune response to SARS-CoV-2 infection and COVID-19 vaccination, in both the general population and patients with MS on DMTs, has focused on humoral immunity...

Magnetic resonance imaging (MRI) plays an increasingly important role in the diagnosis and prognosis of neurodegenerative diseases. One field of extensive clinical use of MRI is the accurate and automated classification of degenerative disorders. Most of current classification studies either do not mirror medical practice where patients may exhibit early stages of the disease, comorbidities, or atypical variants, or they are not able to produce probabilistic predictions nor account for uncertainty. Also, the spatial heterogeneity of the brain alterations caused by neurodegenerative processes is not usually considered, despite the spatial configuration of the neuronal loss is a characteristic hallmark for each disorder...

Recently, we detected a previously unknown Ser-Pro-Cys (SPC) tripeptide in the blood serum of multiple sclerosis patients. Its role as a biomarker of the autoimmune disease was suggested, although its origin and real biological activity remained unclear. Here, we created a biocompatible PEGylated comb-like polymer that was used as a platform for covalent immobilization of the SPC, which provided a possibility to explore the biological activity of this tripeptide. This macromolecular conjugate was synthesized via a reaction of the terminal epoxide group of the biocompatible copolymer of dimethyl maleate (DMM) and polyethylene glycol methyl ether methacrylate (PEGMA) with the amino group of the SPC tripeptide...

Tremor is a debilitating symptom that can lead to functional impairment. Pharmacotherapy is often successful, but up to 50% of patients are resistant to medications or cannot tolerate side effects. Thalamotomy to the ventral intermediate nucleus of the thalamus is a surgical intervention for refractory tremor. Thalamotomy surgeries include radiofrequency and incisionless procedures, such as Gamma Knife radiosurgery and magnetic resonance-guided focused ultrasound. Cognitive changes following thalamotomy have been inconsistently reported across studies...

Multiple sclerosis (MS) is a demyelinating, autoimmune and inflammatory disease that affects the central nervous system (CNS) and is one of the leading causes of disability in young adults worldwide. There are different drugs for the treatment of MS that aim to modify the natural course of the disease and thus slow its progression. This group of drugs is known as disease modifying therapy (DMT). To evaluate the effectiveness of these drugs, mainly clinical and MRI parameters are used. In recent years, different studies have emerged that propose the use of biomarkers to improve the evaluation of the effectiveness of DMT and to provide individualized therapy...

Multiple sclerosis is a frequent condition where the diagnosis relies on clinical presentation, neurologic examination, cerebro spinal fluid markers, and diagnostic imaging tests; however, atypical variants of the disease can lead to misdiagnosis in some scenarios. Herein, we describe a case of a 24-year-old patient with multiple sclerosis with megacystic plaques, in which appropriate interpretation of the imaging findings lead to a proper diagnosis and treatment.

The trans-activation response DNA-binding protein of 43kDa (TDP-43) is involved in the pathogenesis of multiple brain disorders. As scientists are unraveling TDP-43 function and its impact on various diseases, we have begun to subcategorize them into TDP-43 proteinopathies. Furthermore, glial cell dysfunction contributes to various disorders, and TDP-43 is involved with glial cells via multiple pathways (direct or indirect) that aggravate the pathophysiology of such disorders. We are only now discovering and understanding the vast and diverse roles TDP-43 plays on neuronal cells and its effects on gliosis and neurodegenerative pathologies...

Multiple sclerosis (MS) is an autoimmune disease characterized by demyelination and axonal loss of the central nervous system (CNS). Despite its spread throughout the world, the mechanisms that determine its onset are still to be defined. Immunological, genetic, viral, and environmental factors and exposure to chemicals may trigger MS. Many studies have highlighted the anti-inflammatory and anti-oxidant effects of medicinal herbs, which make them a natural and complementary treatment for neurodegenerative diseases...

BACKGROUND: Optical coherence tomography angiography (OCT-A) is a novel technique allowing non-invasive assessment of the retinal vasculature. During relapsing remitting multiple sclerosis (RRMS), retinal vessel loss occurs in eyes suffering from acute optic neuritis and recent data suggest that retinal vessel loss might also be evident in non-affected eyes. We investigated whether alterations of the retinal vasculature are linked to the intrathecal immunity and whether they allow prognostication of the future disease course...

Multiple sclerosis (MS) is a chronic and progressive neurological disorder impacting physical, cognitive, and psychosocial health. The disease course, severity, and presence of symptoms differ within and between persons over time and are unpredictable. Given the preference-sensitive nature of many key decisions to be made, and the increasing numbers of disease-modifying therapies, shared decision-making (SDM) with patients seems to be key in offering optimum care and outcomes for people suffering from MS. In this paper, we describe our perspective on how to achieve SDM in patients with MS, following key SDM-elements from established SDM-frameworks...
