Emerald Health Pharmaceuticals’ investigational cannabidiol-derived EHP-101 continues to show potential to ease inflammation and myelin loss (demyelination) — a hallmark of multiple sclerosis (MS) — according to data from healthy volunteers and a mouse model of MS. The data support the advance of EHP-101’s clinical development into…

Ozanimod — an investigational oral therapy up for approval to treat relapsing multiple sclerosis (MS) — lowers the number of white blood cells circulating in the blood, supporting its ability to ease inflammation in the brain and spinal cord. But this treatment also does not affect all…

Using a patient-friendly autoinjector pen to take monthly doses of ofatumumab — an investigational B-cell therapy for relapsing multiple sclerosis (MS) — is bioequivalent to delivering it via a prefilled syringe, and would allow self-administration of the treatment at home, a study shows. Equal effects…

In this column, I’ll be highlighting some of the research presented at this year’s Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum, held last week in West Palm Beach, Florida. #ACTRIMS2020 — Remyelination in Adult Animal Brains Possible via Cell Transplant, Study Says You’ll need…

A protein called dedicator of cytokinesis 8 (DOCK8) is key for the development and expansion of self-reactive immune T-cells that wrongly attack myelin, a study in a mouse model of multiple sclerosis (MS) found. DOCK8 drives the migration and stimulating capacity of dendritic cells — immune cells that ‘teach’…

High-dose vitamin D supplements appear to aggravate inflammation and myelin loss in the brain and spinal cord, and worsen the disability associated with multiple sclerosis (MS), a study in a mouse disease model reported. Excessive use of vitamin D causes calcium levels to…

Transplanting human glial progenitor cells (GPCs) — brain cells able to generate myelin-producing cells — effectively led to remyelination in the brains of adult mice with myelin disorders, a study found. These results were presented at the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum 2020, running…

Immune system cells can either trigger or suppress inflammation by controlling mitochondrial respiration — the process that occurs in mitochondria, the cells’ powerhouses, and results in the production of usable energy by cells — according to a recent study. This discovery raises the possibility that…

The likelihood of discontinuing treatment with Tysabri (natalizumab) is higher among patients with progressive relapsing multiple sclerosis, and those who smoke and are depressed, a study reported. Progressive relapsing MS (PRMS) is now largely considered a subset of primary progressive MS, or PPMS marked by periods…

Anavex Life Sciences‘ investigational therapy Anavex 2-73 (blarcamesine) showed an ability to protect, repair, and induce the formation of oligodendrocytes — the cells that produce the protective myelin layer around neurons — in early cell testing, researchers reported. These findings, which further establish the therapy’s potential as a treatment…

Immune cells from patients with relapsing-remitting multiple sclerosis (RRMS) respond differently to Tecfidera (dimethyl fumarate) based on age, gender, and serum blood glucose levels, a study found.  The results suggest these patient-specific factors can modulate the response of immune cells, and should be…

Multiple sclerosis (MS) patients switching from Tysabri (natalizumab) to other disease-modifying therapies may have an increased risk of disease activity, though the risk is lower if the switch is limited to three months, a study found. The results were published in an article, “Effect of…

The Spanish version of the modified Story Memory Technique improves learning and life satisfaction of Mexican patients with multiple sclerosis (MS), a new study suggests.  The tool, developed by the Kessler Foundation, has the potential to address the lack of cognitive rehabilitation interventions that are culturally…

Specific mutations in genes that provide instructions to make two proteins —  called C3 and C1q — are linked to increased severity of multiple sclerosis (MS), according to new research. The new finding will be presented by Johns Hopkins University School of Medicine researcher Peter Calabresi, MD, during…

A bone marrow transplant can remove the majority of overactive immune T cells from the central nervous system (CNS) in patients with active relapsing-remitting multiple sclerosis (RRMS), allowing the body to replace them with healthy ones, a study has found. This opens up new treatment avenues to…

Pheno Therapeutics, a spin-off from the University of Edinburgh, in Scotland, will search for new molecules capable of inducing the body to repair or replace the myelin sheath that is damaged in multiple sclerosis (MS). In MS, the body’s own immune system mistakes…

Using brain tissue from people with multiple sclerosis (MS) and mouse models of MS, scientists identified a key pathway that drives astrocytes to promote inflammation in the brain and spinal cord. The study, “MAFG-driven astrocytes promote CNS inflammation” published in the journal Nature, uncovered potential therapeutic targets that may be…

Ocrevus Use Rises Among New Starters with RRMS, Loses Ground to Other Therapies in PPMS Ocrevus (ocrelizumab) bolted out of the starting gate after it was approved for use in the U.S. about three years ago. However, though its use by people with relapsing forms of multiple sclerosis continues…

New data from Public Health England (PHE) and the U.K. MS Society show that the number of people with multiple sclerosis (MS) in the United Kingdom is now more than 130,000 — about one in every 500 people living in the country. This is an increase of…

Placing a feeding tube before age 50 in multiple sclerosis (MS) patients with dysphagia, or difficulties swallowing, may extent their life by more than two years, a study suggests. These findings may help doctors and patients with decisions about feeding tube use, but more work is needed to better understand…

Clene Nanomedicine‘s remyelination therapy candidate, CNM-Au8, showed a “robust” ability to stimulate the production of new myelin and increase the number of myelin-wrapped nerve fibers in the brain and spinal cord of animals in models of demyelinating disease, allowing mice to recover motor skills, a study reports.

Treating people with relapsing-remitting multiple sclerosis (RRMS) for one year with the immune-modulating therapy Gilenya (fingolimod) reduced the numbers of antibody-producing B-cells and of T helper cells, a study finds.  While the…

Progressive cognitive decline in patients with multiple sclerosis (MS) may not be as inevitable as previously thought, a study suggests. The study, “A longitudinal study of cognitive function in multiple sclerosis: is decline inevitable?,” was published in the Journal of Neurology. Statistics indicate that some kind…

Dietary Changes May Delay Development and Progression of MS, Study Finds Methionine is an amino acid found in meat, eggs, and dairy. It’s absorbed by T-cells that are part of our immune system. Those cells are also believed to be the immune cells that attack our myelin, creating the…

People with multiple sclerosis (MS) who self-identify black African or Latin American have a higher number of disease-associated antibody-secreting cells in their blood compared to those who identify as Caucasian, a U.S. study reports.  This difference may account for disparities related to ethnicity in MS…

A way of detecting the density of proteins in the blood, called “magnetic levitation” or MagLev, may aid in more quickly diagnosing chronic diseases, including the particular type of multiple sclerosis suspected in a person, the scientists who developed this method report. Plasma, the liquid component of blood, is composed of…

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…

The immune signaling molecule interleukin-17A (IL-17A) promotes the recruiting of inflammatory cells to the central nervous system (brain and spinal cord) in a multiple sclerosis (MS) mouse model, a study found. The findings support the potential of therapies that target IL-17 in MS. IL-17A is part of the IL-17…

Changing a person’s diet to reduce the amount of methionine (amino acid found in food) could delay the development and progression of inflammatory and autoimmune disorders, including multiple sclerosis (MS). That finding was described in the study “…
