demyelination

The first person with multiple sclerosis (MS) has been successfully imaged in a clinical trial evaluating a new positron emission tomography (PET) tracer designed to detect changes in myelin loss, or demyelination. The Phase 1 study (NCT04699747), a joint effort between Quantum Biopharma and Massachusetts…

Activation of a protein called DLK may drive the death of nerve cells that have been demyelinated, or lost their protective myelin coating, in multiple sclerosis (MS), according to a new study from U.S. researchers. The findings shed light on how a failure to repair lost or damaged…

A small molecule called ESI1 stimulated the repair of the myelin sheath, the fatty coating on nerve fibers that is damaged in multiple sclerosis (MS), a study found. In an MS mouse model, this resulted in improved motor function and nerve cell communication, as well as reduced signs…

Myrobalan Therapeutics has secured $24 million in series A financing to support the development of oral medications for multiple sclerosis (MS) and other diseases of the central nervous system (CNS), which comprises the brain and spinal cord. The company’s pipeline currently includes three candidate therapies…

INmune Bio‘s experimental therapy XPro1595 may promote myelin restoration through the activation of two types of nervous system support cells, according to new data that may lead to novel treatment strategies for multiple sclerosis (MS) and other neurodegenerative disorders. The findings highlight the activation of microglia, key…

Disease-associated inflammatory activity of microglia — a type of immune cell with a central role in the development of multiple sclerosis (MS) — is driven in part by molecular mechanisms that are activated when microglia try to clear the corpses of dead myelin-making cells. That’s according to a new…

A novel tracer designed to detect myelin loss in PET scans — imaging tests that use a radioactive substance, called a tracer, to look for disease in the body — showed a good safety profile in a small first-in-human study. Scientists say this new tracer could potentially help in evaluating…

Two years of treatment with Ocrevus (ocrelizumab) outperformed Rebif (interferon beta-1a) at preventing myelin loss in people with relapsing multiple sclerosis (MS), according to a new analysis of data from the OPERA II clinical trial. Ocrevus’ protection against demyelination was observed both in MS lesions,…

Rune Labs has partnered with Coastal Research Institute (CRI) to identify new and noninvasive biomarkers of the loss of myelin, the fatty sheath surrounding nerve fibers that is progressively damaged by multiple sclerosis (MS). The collaboration involves a patient study that will take advantage of Rune Labs’…

An MRI technique called quantitative susceptibility mapping (QSM) can be used to accurately identify remyelinated brain lesions in people with multiple sclerosis (MS), a research team has discovered. Remyelinated lesions are those in which the myelin sheath — the protective coating around nerve fibers that is progressively lost…

Proteins called tenascins block the regeneration of myelin by modulating the activity of oligodendrocytes, myelin-making cells of the central nervous system, a study in mouse models indicates. “Our research results open up new therapeutic approaches for the treatment of demyelinating diseases such as multiple sclerosis,” Juliane Bauch, a researcher at Ruhr-University…

Immune system reaction to casein, a protein in cow’s milk, can trigger an inflammatory neurological disease in mice that’s similar to multiple sclerosis (MS) and includes the loss of myelin, a study reported. “These results identify how consumption of milk and milk products may exacerbate the autoimmune response in…

Myelin is required for certain inhibitory neurons — which help to suppress abnormal activity in the brain — to work as they should, according to a study in mouse models. Loss of myelin on these neurons results in excessive electric activity in other nerve cells, likely disrupting the brain’s ability…

I want to help in any way I possibly can. My lonely confusion in the early days after being diagnosed with aggressive relapsing-remitting multiple sclerosis was mentally and physically paralyzing. However, this column isn’t about how “Hurricane MS” battered my body. Instead, it’s about why I chose to…

I hate the cold. It triggers my bladder and stiffens my legs. When the leaves start to turn in Maryland, I start thinking about the warm weather in Florida. So, I was interested to read research from the University of Geneva that indicates that exposure to cold…

Fatigue Prevalence Remains High in MS Patients Is this a surprise to anyone who has lived with MS for any period of time? Over the many years since my diagnosis, fatigue has been my second most bothersome symptom. (Trouble walking is the first.) In this survey, researchers write that…

A gene called Mertk has important roles in the repair of myelin, the fatty substance that surrounds and protects neurons and that is lost in multiple sclerosis (MS). The findings were published in Cell Press, in the study “Multiple sclerosis risk gene Mertk is required for…

An estrogen-based therapy, called indazole chloride (IndCl), was shown to protect against optic nerve damage in a mouse model of multiple sclerosis (MS), a study reported. IndCl may help to improve vision in people with the disease, but…

A new primate model uncovered by researchers can help scientists understand the immune and inflammatory processes underlying the development of multiple sclerosis (MS) in humans, a study reports. It was already known that Japanese macaques — also called snow monkeys — can spontaneously develop encephalomyelitis (JME), a disorder that…

There may be a better way of repairing the insulation surrounding damaged neurons that could lead to new treatments for multiple sclerosis (MS), a study suggests. The data showed that blocking the protein sphingomyelin hydrolase neutral sphingomyelinase 2, or nSMase2, could improve the quality of the myelin surrounding…

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…

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…

Myelin is the protective sheath that covers nerve fibers and is damaged in those with multiple sclerosis. Quantifying the degenerative process of myelin would lend perspective to how much and where a patient is progressing. Currently, MRIs are used for diagnostic purposes, but the nuances of progression remain difficult…

Epstein-Barr Virus and Certain Genes Interact in Ways That Can Promote MS, Study Finds Much has been written over the years about a possible connection between the Epstein-Barr virus and multiple sclerosis. Here’s further evidence of a link that has to do with how particular genes interact with the…

Early research in animal models and human samples reveals how loss of communication between nerve cells contributes to the symptoms of multiple sclerosis (MS), and shows how gene therapy could be used to preserve such connections and protect against vision loss. Researchers say their work identifies a…

Exosomes — tiny vesicles secreted by cells — collected from bone marrow stem cells and injected into a mouse model of multiple sclerosis (MS) helped to treat the disease, a study reports. Specifically, this treatment eased myelin loss and neuroinflammation in the mice, and improved motor function, the…

The levels of epsilon toxin are increased in multiple sclerosis (MS) patients, and its presence in laboratory rodents replicated some aspects of disease activity, according to data presented at the 4th Annual Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum. The researchers suggested that the epsilon…

A method based on cerebrospinal fluid measurements and magnetic resonance imaging (MRI) can aid in stratifying patients with multiple sclerosis (MS) at the time of diagnosis, which may help identify a tailored therapeutic approach for each patient from early disease stages. The data was presented by Roberta Magliozzi, from…

Inactivation of S1PR2, a cell surface protein, helps improve clinical disability and reduce demyelination in a mouse model of experimental autoimmune encephalitis (EAE), a condition similar to multiple sclerosis (MS) in humans, a study shows. This finding suggests that therapies blocking S1PR2 could have the potential to treat MS. The…
