The researchers also found that neurons in such lesions exhibited distinct mutation…
By studying pairs of identical twins, researchers have identified a population of immune cells whose early activation and migration into the brain might contribute to multiple sclerosis (MS) onset. MS patients showed an altered profile of a population of immune cells called CD8 T-cells in the blood relative to…
Most patients with nonactive secondary progressive multiple sclerosis (SPMS) who took foralumab nasal spray for at least six months saw a decrease in microglial activity in their brains, according to its developer Tiziana Life Sciences. The results were gleaned from PET imaging data from 10 nonactive SPMS patients…
An abnormally active metabolism in immune B-cells can trigger the release of pro-inflammatory signaling molecules that drive further inflammation in multiple sclerosis (MS), a study found. Selectively blocking certain metabolic processes with a Bruton’s tyrosine kinase (BTK) inhibitor normalized B-cell metabolism and shifted their signaling to an anti-inflammatory state.
In neurological inflammatory conditions like multiple sclerosis (MS), inflammatory immune cells may enter the brain through arachnoid cuff exit (ACE) points — newly discovered structures that normally seem to serve as a type of sewer system in the brain, helping to move out waste. Figuring out exactly how immune…
A diet low in wheat was linked to reductions in circulating inflammatory immune cells and improvements in pain-related life quality among a small group of people with relapsing-remitting multiple sclerosis (RRMS), according to findings from a pilot clinical trial conducted in Germany. The trial’s findings build upon another recent…
The expression of a viral protein known as W-Env leads to the inflammatory activation of brain cells and impairs myelin repair in mouse models of multiple sclerosis (MS), a study reports. “Our study shows that the presence of W-Env in the brains of MS patients appears to generate a…
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…
Inflammation in the membranes around the brain may trigger an inflammatory response that can spread into nearby brain tissue, a new study in a mouse model of multiple sclerosis (MS) shows. Researchers say these findings may help to advance scientists’ understanding of the mechanisms that underlie brain damage in…
A more pro-inflammatory diet is associated with a higher risk of relapses and more inflammatory brain lesions for multiple sclerosis (MS) patients in the years following their first disease attack, according to a recent study. However, dietary intake did not impact disability progression or the volume of lesions with…
Damage to the myelin sheath, a hallmark feature of multiple sclerosis (MS), leads to increased levels of fatty molecules called VLCFAs, which are converted by brain cells into an inflammation-driving signaling molecule called S1P, a study suggests. The discovery of this novel molecular pathway may open up new avenues…
A novel formulation of ibudilast, delivered into the nose, was able to reduce inflammation and prevent nerve damage in a mouse model of multiple sclerosis (MS), a study found. The nasal formulation also improved regeneration of myelin, the protective sheath around nerve fibers that is progressively lost…
A certain bacterial species is enriched in the gut of people with secondary progressive multiple sclerosis (SPMS) and may promote neuroinflammation and drive disability progression in these patients, a study found. When isolated from SPMS patients and given to a mouse model, this strain led to more pronounced neurological…
Using a new approach, researchers have identified new signaling molecules that regulate the activation of certain subsets of astrocytes thought to drive inflammation in multiple sclerosis (MS). The new methodology, called FIND-seq, enables the selection of single cells from a sample based on the expression of specific genes and…
Individuals with primary progressive multiple sclerosis (PPMS) have significantly higher concentrations of specific inflammation biomarkers in their spinal fluid than healthy people, an exploratory study shows. For most biomarkers, levels in PPMS patients were comparable to or lower than those seen in people with relapsing-remitting multiple sclerosis (RRMS).
Tiziana Life Sciences plans to request a meeting with the U.S. Food and Drug Administration (FDA) later this year to discuss the upcoming Phase 2 clinical trial of foralumab nasal spray in people with nonactive secondary progressive multiple sclerosis (SPMS). FDA feedback on the design of the…
EHP-101, an experimental treatment being clinically tested for multiple sclerosis (MS), activates a cellular signaling pathway that promotes blood vessel development and reduces inflammation following brain injury, a new study shows. The findings continue to support the use of EHP-101 in MS, a condition marked by excess inflammation and…
Guar gum, a type of dietary fiber that can be taken as a supplement, lessened inflammation and disease severity in a mouse model of multiple sclerosis (MS), a new study reports. While fiber-rich diets have long been recommended to improve overall health, these findings help pinpoint which fibers have…
A set of receptors involved in dopamine signaling may play a key role in the activation of astrocytes, nerve support cells that contribute to the inflammation that drives multiple sclerosis (MS), according to a study in a mouse model of the neurodegenerative disease. Mice lacking these receptors — called dopamine…
Exercise prior to being diagnosed with multiple sclerosis (MS) was associated with less depression and anxiety among patients, likely due to a reduction in the levels of an inflammatory molecule called interleukin-2 (IL-2), a study revealed. “This finding supports the notion that exercise in the early stages may act…
An eight-week calorie-restricted diet plan — known as intermittent fasting — led to immune and metabolic changes among people with multiple sclerosis (MS) in a small pilot clinical trial, data show. The findings could underlie some of the proposed benefits of calorie restriction on MS disease course, the researchers…
Administering the maresin-1 molecule — a natural anti-inflammatory in the body — in a mouse model of multiple sclerosis (MS) led to lower levels of inflammation and improved neurological function, a recent study showed.
