Multiple sclerosis (MS) is a chronic disorder resulting from destruction of the myelin or insulating covers of neurons in the central nervous system (CNS). Several lines of evidence suggest a role for immune response in the occurrence and progression of this disorder. Several disease-modifying agents (DMA) including β-interferons (IFNβ) are being used in MS patients in order to stop the disease at the early inflammatory stage, postpone disease progression and diminish future disability. Phospholipase D1 (PLD1) is a critical enzyme responsible for the making lipid second messenger phosphatidic acid...

1,2-dihydro-4-hydroxy-2-oxo-1,8-naphthyridine-3-carboxamide derivative VL15 has been recently developed as a selective cannabinoid CB2 receptor compound. Given the high selectivity of this compound at the cannabinoid CB2 receptor and the well-known protective function of this receptor in neurological disorders with autoimmune component like multiple sclerosis, we assessed the immunomodulatory properties of VL15. We assessed on activated peripheral blood mononuclear cells (PBMC), proliferation and viability, cell cycle progression and measured activation markers and the expression of phosphorylated proteins...

BACKGROUND: Multiple sclerosis (MS) is a chronic, inflammatory, progressive, disabling autoimmune disease affecting the central nervous system. Symptoms and signs of MS vary widely and patients may lose their ability to walk. To date the benefits of aquatic therapy often used for rehabilitation in MS patients have not been reviewed. OBJECTIVE: To systematically review the current state of aquatic treatment for persons with MS (hydrotherapy, aquatic therapy, aquatic exercises, spa therapy) and to evaluate the scientific evidence supporting the benefits of this therapeutic option...

Morphea, or localized scleroderma, is an inflammatory disease that leads to sclerosis of the skin and underlying tissues due to excessive collagen deposition. Oral involvement is unusual and it may produce white linear fibrotic areas with a scar-like appearance, atrophy of tongue papillae, gingival recession and alveolar bone resorption. We report a case of a 13-year-old girl who consulted for progressive recession on the attached gingiva of her upper left incisors. She also presented a hypopigmented line on the left side skin of her upper lip, which continued through the vermilion and the lip mucosa, including the gingiva of the affected teeth...

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS). There is increasing evidence that MS is not only characterized by immune mediated inflammatory reactions, but also by neurodegenerative processes. There is cumulating evidence that neurodegenerative processes, for example mitochondrial dysfunction, oxidative stress, and glutamate (Glu) excitotoxicity, seem to play an important role in the pathogenesis of MS. The alteration of mitochondrial homeostasis leads to the formation of excitotoxins and redox disturbances...

Amyotrophic lateral sclerosis (ALS) is the most common degenerative disease of the motor neuron system. Over the last years, a growing interest was aimed to discovery new innovative and safer therapeutic approaches in the ALS treatment. In this context, the bioactive compounds of Cannabis sativa have shown antioxidant, anti-inflammatory and neuroprotective effects in preclinical models of central nervous system disease. However, most of the studies proving the ability of cannabinoids in delay disease progression and prolong survival in ALS were performed in animal model, whereas the few clinical trials that investigated cannabinoids-based medicines were focused only on the alleviation of ALS-related symptoms, not on the control of disease progression...

REVIEW
Fabio Guerriero, Giovanni Ricevuti
Increasing evidence shows that extremely low frequency electromagnetic fields (ELF-EMFs) stimulation is able to exert a certain action on autoimmunity and immune cells. In the past, the efficacy of pulsed ELF-EMFs in alleviating the symptoms and the progression of multiple sclerosis has been supported through their action on neurotransmission and on the autoimmune mechanisms responsible for demyelination. Regarding the immune system, ELF-EMF exposure contributes to a general activation of macrophages, resulting in changes of autoimmunity and several immunological reactions, such as increased reactive oxygen species-formation, enhanced phagocytic activity and increased production of chemokines...

Sonic hedgehog (Shh) is a morphogen essential to the developing nervous system that continues to play an important role in adult life by contributing to cell proliferation and differentiation, maintaining blood-brain barrier integrity, and being cytoprotective against oxidative and excitotoxic stress, all features of importance in amyotrophic lateral sclerosis (ALS). ALS is a fatal disease characterized by selective loss of motor neurons due to poorly understood mechanisms. Evidence indicates that Shh might play an important role in ALS, and that Shh signaling might be also adversely affected in ALS...

In the past, the blood-brain barrier (BBB) had been characterized mainly as a layer of endothelial cells forming the vessel/capillary wall of the brain. More recently, the BBB is considered to be a part of a highly dynamic and interactive system called the neurovascular unit (NVU), consisting of vascular cells, glial cells, and neurons. The list of central nervous system (CNS) pathologies involving BBB dysfunction is rapidly growing. The opening of the BBB and subsequent infiltration of serum components to the brain can lead to host of processes resulting in progressive synaptic and neuronal dysfunction and loss...

Neutrophils are essential to a healthy life, yet pose a threat if improperly controlled. Neutrophil perversion is well documented in a variety of inflammatory disorders (e.g. arthritis, lupus, psoriasis), but is only beginning to be demystified in autoimmune demyelination, the most common cause of neurological disability in young adults. Using the animal model experimental autoimmune encephalomyelitis (EAE), several molecules that help neutrophils invade the central nervous system (CNS) have been identified...

Despite some case reports and small series of women with silicone breast implants (SBI) developing Systemic Sclerosis (SSc), no clear evidence of an association of SBI with SSc is available. However, SSc is characterized by clinical and immunological heterogeneity and autoantibodies are currently the best markers to stratify this heterogeneity of patients. Therefore, we have reviewed the literature for details of autoantibody characterization in reports of SSc associated with SBI. Moreover, the case of an anti-RNA polymerase III-positive SSc with rapid onset and progression, in which SBI rupture was found is described...

PURPOSE OF REVIEW: This article is a practical guide to identifying uncommon causes of stroke and offers guidance for evaluation and management, even when large controlled trials are lacking in these rarer forms of stroke. RECENT FINDINGS: Fabry disease causes early-onset stroke, particularly of the vertebrobasilar system; enzyme replacement therapy should be considered in affected patients. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), often misdiagnosed as multiple sclerosis, causes migraines, early-onset lacunar strokes, and dementia...

OBJECTIVES: Wnt signalling has been implicated in activating a fibrogenic programme in fibroblasts in systemic sclerosis (SSc). Porcupine is an O-acyltransferase required for secretion of Wnt proteins in mammals. Here, we aimed to evaluate the antifibrotic effects of pharmacological inhibition of porcupine in preclinical models of SSc. METHODS: The porcupine inhibitor GNF6231 was evaluated in the mouse models of bleomycin-induced skin fibrosis, in tight-skin-1 mice, in murine sclerodermatous chronic-graft-versus-host disease (cGvHD) and in fibrosis induced by a constitutively active transforming growth factor-β-receptor I...

BACKGROUND: Astrocytes are the most abundant cell type in the central nervous system (CNS) and secrete various factors that regulate neuron development, function and connectivity. microRNAs (miRNAs) are small regulatory RNAs involved in posttranslational gene regulation. Recent findings showed that miRNAs are exchanged between cells via nanovesicles called exosomes. In this study, we sought to define which miRNAs are contained within exosomes secreted by astrocytes. We also explored whether astroglial miRNA secretion via exosomes is perturbed in a mouse model of amyotrophic lateral sclerosis (ALS), a neurodegenerative disease where astrocytes play a crucial role in driving disease progression...

Multiple sclerosis (MS) is an autoimmune disease characterized by demyelination, axonal damage and progressive neurologic dysfunction in central nervous system (CNS). Many evidences show that B cells play an important role in the pathogenesis of MS. Follicular helper T cells (Tfh) secrete IL-21 to prompt the proliferation and differentiation of B cells in germinal center (GC) through clonal proliferation, somatic hypermutation, antibody class switching, antibody affinity maturation process. AG490 is a synthetic inhibitor to JAK-STAT signal pathway, which has been studied in inflammatory, tumor and autoimmune diseases...

Scleroderma (or systemic sclerosis, SSc) is a disease caused by excess crosslinking of collagen. The skin stiffens and becomes painful, while internally, organ function can be compromised by the less elastic collagen. Diagnosis of SSc is often only possible in advanced cases by which treatment time is limited. A more detailed analysis of SSc may provide better future treatment options and information of disease progression. Recently, the histological stain picrosirius red showing collagen register has been combined with atomic force microscopy (AFM) to study SSc...

Disruption of the blood-brain barrier (BBB) is a defining and early feature of multiple sclerosis (MS) that directly damages the central nervous system (CNS), promotes immune cell infiltration, and influences clinical outcomes. There is an urgent need for new therapies to protect and restore BBB function, either by strengthening endothelial tight junctions or suppressing endothelial vesicular transcytosis. Although wingless integrated MMTV (Wnt)/β-catenin signaling plays an essential role in BBB formation and maintenance in healthy CNS, its role in BBB repair in neurologic diseases such as MS remains unclear...

Huntington's disease (HD) is a fatal degenerative autosomal dominant neuropsychiatric disease that causes neuronal death and is characterized by progressive striatal and then widespread brain atrophy. Brain-derived neurotrophic factor (BDNF) is a lead candidate for the treatment of HD, as it has been shown to prevent cell death and to stimulate the growth and migration of new neurons in the brain in transgenic mouse models. BDNF levels are reduced in HD postmortem human brain. Previous studies have shown efficacy of mesenchymal stem/stromal cells (MSC)/BDNF using murine MSCs, and the present study used human MSCs to advance the therapeutic potential of the MSC/BDNF platform for clinical application...

Multiple sclerosis (MS) is an autoimmune, demyelinating disease of the central nervous system (CNS). It predominantly affects young women and is one of the most common causes of disability in young adults. MS is characterized by formation of white matter lesions in the CNS as a result of inflammation, demyelination, and axonal loss. Treatment has been a focus of neurological research for over 60 years. A number of disease-modifying therapies (DMTs) have become available making MS a treatable disease. These compounds target the inflammatory response in MS...
