REVIEW
Harold L Atkins, Mark S Freedman
Multiple sclerosis (MS) is thought to be an autoimmune disease targeting the central nervous system leading to demyelination, and axonal and neuronal damage, resulting in progressive disability. More intensive therapies such as immunodepletion with hematopoietic stem-cell rescue are being used at a time prior to patients becoming irreversibly disabled. Over the last 15 years, there has been a shift away from using autologous hematopoietic stem-cell transplants (aHSCT) to treat patients with progressive MS, towards treating those with active inflammation and relapses...

Oligodendrocytes, the myelin-producing cells of the central nervous system (CNS), have limited capability to bring about repair in chronic CNS neuroinflammatory demyelinating disorders such as multiple sclerosis (MS). MS lesions are characterized by a compromised pool of undifferentiated oligodendrocyte progenitor cells (OPCs) unable to mature into myelin-producing oligodendrocytes. An attractive strategy may be to replace lost OLs and/or promote their maturation. N-palmitoylethanolamine (PEA) is an endogenous fatty acid amide signaling molecule with anti-inflammatory and neuroprotective actions...

The alteration of DNA methylation patterns are a key component of disease onset and/or progression. Our objective was to evaluate the differences in Long Interspersed Nuclear Element-1 (LINE-1) methylation levels, as a surrogate marker of global DNA methylation, between multiple sclerosis (MS) patients and healthy controls. In addition, we assessed the association of LINE-1 methylation with clinical disease activity in patients treated with IFNbeta (IFNβ). We found that individuals with high levels of LINE-1 methylation showed 6-fold increased risk of suffering MS...

Multiple Sclerosis (MS) is an immune-mediated demyelinating disease of the human central nervous system (CNS). Memory impairments and hippocampal demyelination are common features in MS patients. Our previous data have shown that demyelination alters neuronal gene expression in the hippocampus. DNA methylation is a common epigenetic modifier of gene expression. In this study, we investigated whether DNA methylation is altered in MS hippocampus following demyelination. Our results show that mRNA levels of DNA methyltransferase were increased in demyelinated MS hippocampus, while de-methylation enzymes were decreased...

Denervation of the neuromuscular junction (NMJ) precedes the loss of motor neurons (MNs) in amyotrophic lateral sclerosis (ALS). ALS is characterized by a motor unit (MU) dependent vulnerability where MNs with fast-fatigable (FF) characteristics are lost first, followed by fast-fatigue resistant (FR) and slow (S) ones. However, changes of NMJ properties as a function of MU types remain debated. We hypothesized that NMJ synaptic functions would be altered precociously in a MU specific manner, prior to structural alterations of the NMJ...

Cell-type specific changes in neuronal excitability have been proposed to contribute to the selective degeneration of corticospinal neurons in amyotrophic lateral sclerosis (ALS) and to neocortical hyperexcitability, a prominent feature of both inherited and sporadic variants of the disease, but the mechanisms underlying selective loss of specific cell types in ALS are not known. We analyzed the physiological properties of distinct classes of cortical neurons in the motor cortex of hSOD1(G93A) mice of both sexes and found that they all exhibit increases in intrinsic excitability that depend on disease stage...

REVIEW
Jeffrey R Liddell
Nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor that regulates hundreds of antioxidant genes, and is activated in response to oxidative stress. Given that many neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease and multiple sclerosis are characterised by oxidative stress, Nrf2 is commonly activated in these diseases. Evidence demonstrates that Nrf2 activity is repressed in neurons in vitro, and only cultured astrocytes respond strongly to Nrf2 inducers, leading to the interpretation that Nrf2 signalling is largely restricted to astrocytes...

The aim of this work was to assess the state of the fallopian tubes in women with urogenital chlamydia (UC) and infertility. 344 women 18-49 y.o with infertility have been investigated. UC was detected in 133 of them -38.7%, (main group), UC was absent in 211 (61.3%) patients (comparision group). In the main group prevailed the tubal or tubal peritoneal factor of infertility (51.9% versus 19.4% in the comparison group, p<0.001). UC in women in the main (62.4%) was in the form of mixed infection. Obstruction of the fallopian tubes and adhesions in the pelvic region were more often detected in patients of the main group (p<0...

The translocator protein (TSPO) is a commonly used imaging target to investigate neuroinflammation. While TSPO imaging demonstrates great promise, its signal exhibits substantial interindividual variability, which needs to be accounted for to uncover group effects that are truly reflective of neuroimmune activation. Recent evidence suggests that relative metrics computed using pseudo-reference approaches can minimize within-group variability, and increase sensitivity to detect physiologically meaningful group differences...

Patients with connective tissue disease-associated pulmonary arterial hypertension (PAH-CTD) have a poor prognosis compared with other aetiologies. The underlying CTD can influence treatment response and outcomes. We characterised the GRIPHON study PAH-CTD subgroup and evaluated response to selexipag.Of 334 patients with PAH-CTD, PAH was associated with systemic sclerosis (PAH-SSc) in 170, systemic lupus erythematosus (PAH-SLE) in 82 and mixed CTD/CTD-other in 82. For the primary composite endpoint of morbidity/mortality, hazard ratios (HR) and 95% CI were calculated using Cox proportional hazard models...

Dietary supplementation of vitamin D is commonly recommended to patients with multiple sclerosis. We recently found that high-dose of the hormonally active 1,25-dihydroxyvitamin-D3 (1,25D) promotes myelin repair in the cuprizone model for de- and remyelination. In the present study, we quantified 5062 proteins, of which 125 were differentially regulated in brain tissue from 1,25D treated mice during remyelination, compared to placebo. Proteins upregulated in the early remyelination phase were involved in calcium binding, e...

Oxidative stress is recognised as central in a range of neurological diseases including Amyotrophic lateral sclerosis (ALS), a disease characterised by fast progressing death of motor neurons in the brain and spinal cord. Cellular pathology includes cytosolic protein aggregates in motor neurons and glia of which potentially cytotoxic hyper-phosphorylated fragments of the Transactive response DNA Binding Protein 43 kDa (TDP-43) constitute a major component. This is closely associated with an additional loss of nuclear TDP-43 expression indicating a "loss of function" mechanism, accelerating motor neuron (MN) loss...

Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are age-related neurodegenerative disorders with shared genetic etiologies and overlapping clinical and pathological features. Here we studied a novel ALS/FTD family and identified the P362L mutation in the low-complexity domain (LCD) of T cell-restricted intracellular antigen-1 (TIA1). Subsequent genetic association analyses showed an increased burden of TIA1 LCD mutations in ALS patients compared to controls (p = 8.7 × 10(-6)). Postmortem neuropathology of five TIA1 mutations carriers showed a consistent pathological signature with numerous round, hyaline, TAR DNA-binding protein 43 (TDP-43)-positive inclusions...

Amyotrophic lateral sclerosis (ALS) is a progressive fatal neurodegenerative disease that is characterized by the death of motor neurons in the spinal cord, brain stem, and motor cortex that are responsible for voluntary movement. For unknown reasons, military veterans are approximately twice as likely as the public to be given a diagnosis of ALS. Currently, there is no cure for ALS. The only US Food and Drug Administration-approved disease-modifying medication is riluzole (Rilutek), which may slow ALS progression but only minimally increases survival time...
