Oral administration of trehalose — a sugar molecule found in plants and fungi and reported to have neuroprotective effects — eased symptoms and halted disease progression in a mouse model of multiple sclerosis (MS). These benefits were associated with a restoration of the ability of microglia (the brain’s immune cells) to break down…

Human placental extract eased clinical symptoms, inflammation, and weight and myelin loss in a mouse model of multiple sclerosis (MS), a study reported.  Its researchers proposed that placental extracts be investigated as a way of better managing MS symptoms in people. …

Gilenya and Tecfidera Similarly Effective at Treating RRMS, Real-world Study Says Gilenya and Tecfidera are both oral disease-modifying therapies. Both meds attempt to limit the inflammatory action of the immune system. Both now have generic versions. And as this story reports, neither appears to have a leg up over…

Oral administration of N-acetylglucosamine (GlcNAc) — a natural simple sugar sold as a dietary supplement — prevents myelin degeneration and loss of motor function in a mouse model of multiple sclerosis (MS). Myelin, the protective sheath around nerve fibers that helps to speed transmission of signals between nerve cells, is damaged…

A pathway controlled by three proteins — Daam2, Nedd4, and VHL — was identified by researchers as a key regulator of myelin production during central nervous system development and regeneration after injury. Myelin, the protective fatty layer that covers nerve fibers and helps to speed transmission of signals between nerve cells,…

The National Multiple Sclerosis Society has awarded a two-year, $373,000 Fast Forward grant to researchers at the University of California Riverside School of Medicine to identify compounds best able to replace myelin lost over the course of multiple sclerosis (MS), according to a press release.

Dutch Amarna Therapeutics announced a research collaboration with Spanish Progreso y Salud Foundation (FPS) to investigate the efficacy of its gene therapy delivery technology in multiple sclerosis (MS) and diabetes. MS is thought to be caused by immune-mediated inflammation that damages myelin — an insulating sheath around nerve…

Remyelination — or the restoration of lost myelin, the protective sheath surrounding nerve cell fibers — in multiple sclerosis (MS) depends mainly on pre-existing oligodendrocytes (myelin-producing cells), rather than on newly-generated oligodendrocytes, according to a recent study. The data also showed that perineuronal, or satellite,…

Tolebrutinib (SAR442168), an investigational oral BTK inhibitor to treat relapsing forms of multiple sclerosis (MS), was seen to prevent the loss of myelin when given to a mouse model of demyelination in a preclinical study. The investigative therapy achieves this by preventing…

Two specific bacteria present together in the gut led to more immune attacks on myelin and harsher symptoms in a mouse model of multiple sclerosis (MS). These findings add to existing evidence supporting the link between gut microbiota and MS, and highlight the need to consider potential combined effects of these…

Chemical modification of the protein eukaryotic elongation factor 1A1 (eEF1A1) regulates remyelination, a new study suggests, indicating that the processes regulating this protein may provide useful therapeutic targets for multiple sclerosis (MS). The study, “EEF1A1 deacetylation enables transcriptional activation of remyelination,” was published in Nature Communications.

Anacardic acid, a compound found in cashew nuts, promoted myelin regeneration and eased neuronal damage and disability in two mouse models of multiple sclerosis (MS). These protective effects were associated with maturation of myelin-producing cells and production of IL-33, an immune-related molecule with a neuroreparative role in the central…

A protein known as Gsta4 is critical in the growth and activity of oligodendrocytes, a special type of brain cell that generates the myelin sheath that is damaged in multiple sclerosis (MS), a study shows. The overproduction of Gsta4 in…

For the first time, scientists have shown that a protein known as CD36 on the surface of some immune cells is crucial for clearing myelin debris and suppressing nerve cell inflammation in disorders such as multiple sclerosis (MS), according to a new…

A “prudent” diet rich in fresh fruit, non-fried fish, whole grains, vegetables, and nuts may lower the likelihood of a relapse in people with a first demyelinating event, a major risk factor for multiple sclerosis (MS), a study in Australia suggests. While the researchers did not find a strong link…

NeuroScientific Biopharmaceuticals (NSB)’s lead candidate EmtinB induces significantly greater myelin regeneration in a cellular model of multiple sclerosis (MS) than the market-leading therapy Copaxone, the company announced. “These results represent a potential breakthrough in the treatment of MS as there are currently no approved therapeutic drugs available to patients that…

Loss of myelin in nerve cell fibers — the hallmark of multiple sclerosis (MS) — leads to a shortage of mitochondria, a cell’s powerhouse, denying these damaged fibers the energy they need to work as intended, a new study shows. Boosting the migration of mitochondria to affected nerve…

Note: A story mentioned in this column, “Prime Signs Agreement With EMD Serono to Improve Mavenclad’s Cost-benefit Value,” was updated on June 15, 2020, to clarify that the agreement allows for possible reimbursement for Prime’s health plan clients, not patients…

Autobahn Therapeutics announced its launch with $76 million in financing to support work on therapies for central nervous system (CNS) disorders, including ABX-002, its lead candidate to treat diseases marked by the loss of myelin, such as …

After repeated exposure to a fragment of the myelin protein — the target of autoimmune attack in multiple sclerosis (MS) — immune cells in mice were reprogrammed to be tolerant to myelin, suppressing the immune response associated with the disease, a study revealed.  Researchers showed that in these…

Human glial progenitor cells — forerunners of nerve cells that protect and support neurons — transplanted into adult mice in a model of multiple sclerosis (MS) were seen to restore myelin production and motor function in the animals. This study and others it builds on “establish an operational…

Movements that are an act of “learning” motor tasks after lesions appear in the protective myelin sheath of neurons seem to induce both new and existing oligodendrocytes — the cells that make up myelin — to repair those lesions, a study in mice shows. Precisely timed rehabilitation programs and exercise may…
