The evolution of the myelin sheath throughout childhood has been visualized in vivo for a first time, according to findings reported in the study “Mapping an index of the myelin g-ratio in infants using magnetic resonance imaging,” published in the journal NeuroImage. To function well, nerve cells in the brain rely on…

Researchers at the Center of Excellence for Myelin Repair, a part of Mount Sinai, reported that gut bacteria produce compounds that were seen to affect the myelin content in mice and cause social avoidance behaviors. Study results indicated that targeting gut bacteria, or the gut metabolites, might help in treating neuropsychiatric disorders or complications, such as those…

Dr. Claudia Lucchinetti, chair of the Department of Neurology at the Mayo Clinic and the Eugene and Marcia Applebaum Professor of Neurosciences, has received the 2016 John Dystel Prize for Multiple Sclerosis Research, an honor jointly awarded by the National Multiple Sclerosis Society and the American Academy of Neurology…

Neuregulin-1 is a signaling molecule of interest in the context of synaptic plasticity ­— the ability of our nerve cells to form new connections and get rid of those that are no longer needed. Now, a study showed that the factor is also indispensable for repairing myelin in models of spinal…

Multiple sclerosis was a main focus at the four-day 10th World Congress on Controversies in Neurology (CONy), in Lisbon, Portugal, that concluded on March 20. Among the topics of debate was demyelination as the disease’s main pathogenic precursor and the clinical potential of remyelination. The debate, titled “Can we expect long-term…

Researchers found that nerve cell connections in the brain, called synapses, were damaged in a mouse model of multiple sclerosis (MS) through a process wholly unrelated to myelin destruction. As the damaged mice synapses studied were in regions crucial for memory processing, finding ways of protecting these neurons would be a crucial step toward developing a…

RegeneRx Biopharmaceuticals, Inc., announced the publication of a research article detailing the process by which Thymosin beta 4 (Tβ4), the company’s novel therapeutic peptide, effectively promoted the remyelination process in two separate animal models commonly used for multiple sclerosis (MS) research. The article, “Thymosin beta4 promotes oligodendrogenesis in the demyelinating…

Researchers from Karolinska Institute, Sweden, reported that the immune-associated protein lipocalin-2 (LCN2) is increased in multiple sclerosis, particularly in patients with progressive MS. The researchers, however, concluded that the factor cannot be used as a biomarker for the disease. The study, “Lipocalin-2 is increased in progressive multiple sclerosis…

Premature infants are known to be at risk of cerebral injury due to oxygen deprivation and later problems with cognitive development, but an immunomodulating drug mostly used in the treatment of multiple sclerosis (MS) may be of help. Researchers in Germany and Switzerland reported that the drug fingolimod (Gilenya) prevented brain…

Researchers have described the mechanisms by which cell precursors of oligodendrocytes — the cells responsible for the generation of myelin in the central nervous system — migrate from their birthplace to their workplace during brain and spinal cord development, and begin to mature and wrap about nerve fibers. The finding, the authors…

A study from the University of Cambridge showed that the membrane-bound signaling protein EphrinB3, which acts by inhibiting the maturation of oligodendrocytes, also blocks the remyelination of damaged neurons in multiple sclerosis (MS). The study, “Antibody-mediated neutralization of myelin-associated EphrinB3 accelerates CNS re-myelination,“ uncovered a new target to explore…

A new study from The Weizmann Institute of Science, Israel, found that the inflammatory molecule CXCL12 promotes neuronal repair during spontaneous remission in mice with experimental autoimmune encephalomyelitis (EAE), an animal model of human multiple sclerosis (MS). The chemokine CXCL12 was previously thought to be a pro-inflammatory molecule only. But recent findings have shown…

Novoron Bioscience, Inc., a biotech company focused on developing therapies for disorders of the central nervous system, recently announced that it has received a $680,000 National Institutes of Health (NIH) grant to assess the potential of a new therapeutic approach to induce remyelination in multiple sclerosis (MS). MS is…

Researchers are proposing for a first time that multiple sclerosis (MS) is triggered by the death of a specific cell population within the central nervous system called oligodendrocytes. The study, titled “Oligodendrocyte death results in immune-mediated CNS demyelination,” was published in the journal Nature Neuroscience. Oligodendrocytes,…

Researchers in the United Kingdom recently discovered that a small molecule triggers the destruction of axons, a phenomenon observed in neurodegenerative diseases like multiple sclerosis (MS). The study is titled “Wallerian Degeneration Is Executed by an NMN-SARM1-Dependent Late Ca2+ Influx but Only Modestly Influenced by Mitochondria” and appears in the journal…

A new study in the Journal of Cell Biology suggests that vitamin D activates a receptor involved in myelin regeneration in patients with multiple sclerosis (MS). The study, entitled “Vitamin D receptor–retinoid X receptor heterodimer signaling regulates oligodendrocyte progenitor cell differentiation,” and was led by researchers…

In a new study, researchers have revealed the previously unknown function of the FAM126A gene in supporting myelination (the formation of the myelin sheath that protects neurons), a critically important process in the development and recovery of acute exacerbations in multiple sclerosis (MS). The research paper, entitled “The leukodystrophy protein…

The Multiple Sclerosis Society (MS Society) in the United Kingdom recently announced the investment of £1.98 million in new MS research. The 16 projects awarded funding through the MS Society’s 2015 grant round were thoroughly evaluated in a rigorous review process. In total, 58 projects applied for MS Society…

In a recent study entitled “Myelin oligodendrocyte glycoprotein (MOG35-55)-induced experimental autoimmune encephalomyelitis is ameliorated in interleukin-32 alpha transgenic mice,” a team of researchers investigated whether interleukin (IL)-32, a cytokine with an established role in rheumatoid arthritis, has a protective function in a mouse model of human multiple…

In a recent study entitled “Promotion of Remyelination by Sulfasalazine in a Transgenic Zebrafish Model of Demyelination,” researchers investigated whether sulfasalazine treatment, an anti-inflammatory and immune-modulating drug, could promote remyelination of axons in an organism model of demyelination diseases such as multiple sclerosis (MS). The study was published in the…

Moreover, this mechanism is crucial for immune cells to function properly…

Japanese scientists have discovered new information about how the myelin sheath is repaired following damage. Myelin is a fatty substance that wraps around nerve cells and helps them to conduct impulses. The research could have major implications for how multiple sclerosis is understood and even treated. The study, titled “Inactivation…

A recent research study focused on whether regular exercise can benefit children with multiple sclerosis (MS). The article appeared in the August 12, 2015, online issue of Neurology, the medical journal of the American Academy of Neurology. MS is characterized by inflammation, which manifests as an…

Multiple sclerosis (MS) is a devastating, progressive disease of the nervous system. It is caused by loss of myelin, a fatty substance that wraps around nerve cells and allows them to conduct impulses and communicate. When myelin is lost, areas of damage called “lesions” result, which appear in the brain and…
