An autoimmune demyelination disease of the Central Nervous System, Multiple Sclerosis, is a chronic inflammation which mostly involves young adults. Suffering people face functional loss with a severe pain. Most current MS treatments are focused on the immune response suppression. Approved drugs suppress the inflammatory process, but factually, there is no definite cure for Multiple Sclerosis. Recently developed knowledge has demonstrated that gene and cell therapy as a hopeful approach in tissue regeneration...

Oligodendroglial cell death and demyelination are hallmarks of neurotrauma and multiple sclerosis that cause axonal damage and functional impairments. Remyelination remains a challenge as the ability of endogenous precursor cells for oligodendrocyte replacement is hindered in the unfavorable milieu of demyelinating conditions. Here, in a rat model of lysolecithin lysophosphatidyl-choline (LPC)-induced focal demyelination, we report that Neuregulin-1 (Nrg-1), an important factor for oligodendrocytes and myelination, is dysregulated in demyelinating lesions and its bio-availability can promote oligodendrogenesis and remyelination...

Remyelination in the CNS is the natural process of damage repair in demyelinating diseases such as multiple sclerosis (MS). However, remyelination becomes inadequate in many people with MS, which results in axonal degeneration and clinical disability. Enhancement of remyelination is a logical therapeutic goal; nevertheless, all currently licensed therapies for MS are immunomodulatory and do not support remyelination directly. Several molecular pathways have been identified as potential therapeutic targets to induce remyelination, and some of these have now been assessed in proof-of-concept clinical trials...

Pain is a common and severe symptom in multiple sclerosis (MS), a chronic inflammatory and demyelinating disease of the central nervous system. The neurobiological mechanism underlying MS pain is poorly understood. In this study, we investigated the role of Ca(2+)/calmodulin dependent kinase type IIα (CaMKIIα) in driving chronic pain in MS using a mouse experimental autoimmune encephalomyelitis (EAE) model. We found that spinal CaMKIIα activity was enhanced in EAE correlating with the development of ongoing spontaneous pain and evoked hypersensitivity to mechanical and thermal stimuli...

Previous research indicated the association between hepatitis B virus (HBV) infection/vaccination and the onset of demyelinating diseases. However, most of these studies were single case reports, and comprehensive data are still scarce. Here we present a comprehensive analysis of 10 patients with neuromyelitis optica spectrum disorder (NMOSD) combined with chronic hepatitis B (CHB) infection and seropositive for anti-aquaporin-4 antibody (AQP4-Ab). Demographic, clinical, laboratory, neuroimaging, outcome, and follow-up data of the 10 patients were retrospectively analyzed...

An increase in central nervous system (CNS) remyelination and a decrease in CNS inflammation are important steps to halt the progression of multiple sclerosis (MS). RNS60 is a bioactive aqueous solution generated by subjecting normal saline to Taylor-Couette-Poiseuille flow under elevated oxygen pressure. Recently we have demonstrated that RNS60 exhibits anti-inflammatory properties. Here, we describe promyelinating property of RNS60. RNS60, but not normal saline (NS), RNS10.3 (TCP-modified saline without excess oxygen) or PNS60 (saline containing excess oxygen without TCP modification), stimulated the expression of myelin-specific genes and proteins (myelin basic protein, MBP; myelin oligodendrocyte glycoprotein, MOG and proteolipid protein, PLP) in primary mouse oligodendroglia and mixed glial cells...

CLINICAL PROBLEM: Intracerebral cysts are common findings in imaging of the neurocranium and are not always clinically significant. The pathological spectrum of intracerebral cysts is, however, very broad and in addition to incidental findings includes developmental disorders, malformation tumors, primary and secondary neoplasms and infectious etiologies, such as cerebral abscess formation, cysticercosis or residuals after congenital cytomegalovirus infections. Intracerebral cystic defects may be caused by inflammatory central nervous system (CNS) diseases, such as multiple sclerosis as well as by mitochondriopathies, leukodystrophy, electrolyte disturbances or osmotic demyelination syndrome or brain infarctions, e...

Background: Multiple sclerosis (MS) is a severe neurological disorder, characterized by demyelination of the central nervous system (CNS), and with a prevalence of greater than 2 million people worldwide. In terms of research in MS pathology, the cuprizone toxicity model is widely used. Here we investigated the contribution of genetic differences in response to cuprizone-induced demyelination in two genetically different mouse strains: CD1 and C57BL/6. Results: We demonstrate that exposure to a diet containing 0...

A rare acquired demyelinating lesion of the pons central pontine myelinolysis (CPM) typically occurs after rapid correction of hyponatremia. There is disruption of blood-brain barrier due to osmotic stress allowing access for inflammatory mediators in extravascular brain tissue, which most likely attracts glial cells of the brain, attracts macrophages, and activates astrocytes. We present a case of female with a known history of inflammatory bowel disease who presented with altered sensorium and hyponatremia...

Neuromyelitis optica is a severe autoimmune demyelinating disease; however, the trigger for autoimmunity in an individual patient is unclear. Here, we report the case of a 48 year old female presenting with longitudinally extensive transverse myelitis in the cervical region of the spinal cord two weeks post herpes zoster infection in right C6 dermatome. Though post herpetic myelitis was provisionally diagnosed, serological evaluation revealed aquaporin-4 antibody positivity, confirming the diagnosis of neuromyelitis optica spectrum disorder...

We report the case of a patient who initially presented with fever, headache and seizure. MRI revealed a fluid attenuation inversion recovery (FLAIR) high-intensity lesion involving the right temporal, parietal and occipital cortex. Afterwards, the patient developed three recurrent episodes, manifested as brainstem encephalitis, optic neuritis and ADEM-like illness successively, indicating demyelination. Both of his serum anti-MOG and CSF anti-NMDAR antibodies were proved positive by transfected cell based assays...

BACKGROUND: Until recently, the peripheral nervous system (PNS) had been known to be spared in multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD). However, some studies of late have reported PNS damage in demyelination diseases of the central nervous system (CNS) such as MS and NMOSD. Although multiple studies have reported characteristics reminiscent of peripheral neuropathy in MS, there have been limited reports in NMOSD. To investigate the incidence and pathology of peripheral neuropathy in NMOSD, we reviewed articles describing such cases including our own case...

INTRODUCTION: Neural stem cells (NSC) are located essentially in the subventricular zone (SVZ), subgranular zone (SGZ), and along the central canal of the spinal cord. These cells can proliferate in vitro and differentiate into neurons, oligodendrocytes, and astroglia, thus contributing to repair in multiple sclerosis (MS). We conducted a pathological study to analyse neurogenic response in a patient with Marburg variant MS. METHODS: We present the case of a 27-year-old immunocompetent patient with Marburg variant MS, a fulminant form of the disease...

BACKGROUND: Multiple sclerosis (MS) is a chronic inflammatory demyelinating and neurodegenerative disease affecting the central nervous system. One of the basic medications for the treatment of a clinically isolated syndrome (CIS) or relapsing-remitting MS is interferon beta (INFβ). Although the exact mechanism of its effects is unknown, the medication has an anti-inflammatory and immunomodulatory effect. The goal of this study was to determine the characters which are affected in patients treated with INFβ...

In recent years, not only the incidence of brain demyelinating disease has increased, but also it seems that the world is facing new forms of autoimmune diseases of the brain. Distinguishing these diseases from each other is very important, since each requires a different treatment. The new criteria that were put forward in 2015 were meant to pave the way for better diagnosis of these diseases called neuromyelitis optica spectrum disease (NMOSD). However, too much emphasis on the criteria based on the convergence and association of radiological findings with the clinical symptoms actually causes confusion in the diagnosis...
