In multiple sclerosis (MS), inflammation leads to less energy production in nerve fibers by reducing the levels of enzymes in a key molecular pathway, called the TCA cycle, that cells use to generate energy, a new study shows. These findings imply that boosting activity of the TCA cycle might…

Multiple sclerosis (MS)-associated inflammation in the cerebral cortex — the outermost layer of the brain that is involved in cognitive function — prompts the destruction of neural connections by specific immune cells, according to a study in a mouse model of MS. These immune cells targeted dendritic spines (nerve…

Inflammation drives the loss of brain volume and thinning of the eye’s retina in the first five years of a multiple sclerosis (MS) diagnosis, an imaging study demonstrates.  The findings support a therapeutic strategy of halting inflammatory activity during this initial period. …

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…

Eliminating SARM1, an enzyme that plays a key role in nerve cell degeneration, protects neurons in mice with experimental autoimmune encephalomyelitis (EAE), a condition that mimics the key pathological features of multiple sclerosis (MS) in humans. The preclinical findings were presented by researchers at Disarm Therapeutics in a…

The RhoE protein has been identified as being important for axons’  myelination and extension in the central nervous system, two processes that go awry in diseases like multiple sclerosis (MS). The findings stem from Pilar Madrigal’s doctoral thesis, “Role of the small GTPase RhoE in myelination and axonal tracts development.”…

Tiny ruptures in the cell membrane of nerve fibers enable the entry of calcium and ultimately lead to their degeneration, a study in a mouse model of multiple sclerosis (MS) suggests. The study, “Calcium Influx through Plasma-Membrane Nanoruptures Drives Axon Degeneration in a Model of Multiple…

Blocking SARM1, a protein identified as a central mediator of nerve cell degeneration, works to prevent damage to axons — nerve cell fibers essential in cell-to-cell communication — and may be a way of treating neurodegenerative diseases like multiple sclerosis (MS), data from Disarm Therapeutics shows. Specially, genetically deleting…

Remyelination therapies are on the horizon as an innovative multiple sclerosis (MS) treatment, according to my neurologist. These therapies have been on my radar the last few years, but to hear my neurologist say they could soon be a reality makes me hopeful of the possibilities. To offer a…

The generation of a thin myelin sheath during remyelination — one that continues to protect nerve cells over time — is indicative of the long-term health and activity of the central nervous system (CNS) in demyelinating diseases such as multiple sclerosis (MS), a new study shows. These findings, which aim…

A study found that the cells responsible for the production of myelin selectively introduce a myelin-insulating layer in a particular set of neuronal axons in the brain’s white matter. This represents a step forward in the basic mechanisms that may underlie neurological disorders, including multiple sclerosis (MS). Also, a newly developed method…

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 from Sweden indicates that vitamin D could help protect nerve cells (neurons) in multiple sclerosis (MS). The report, titled “Vitamin D and axonal injury in multiple sclerosis,“ was published on October 13, 2015, in the Multiple Sclerosis Journal. Scientists have demonstrated, in…
