Mitochondrial abnormalities, or problems in the powerhouses of cells, seem to be a main contributor to the death of important nerve cells in the cerebellum — a brain region involved in motor control — in people with multiple sclerosis (MS), a new study suggests. Researchers found that inflammation and…

As multiple sclerosis (MS) progresses, the disease may reduce the number of mitochondrial DNA copies, suggesting the number of copies could serve as a biomarker for disease progression and response to treatment. That’s according to a genetic study involving data from thousands of patients of European ancestry. Mitochondria are…

Mitochon Pharmaceuticals is launching a pilot clinical trial to evaluate MP101, its treatment candidate for improving mitochondrial function, in people with multiple sclerosis (MS) and other neurodegenerative diseases. The announcement follows the trial’s clearance by the European Medicines Agency (EMA), which enables Mitochon to begin enrolling patients with…

Changes in mitochondria — cells’ energy production centers — are evident in early disease stages in a mouse model of progressive multiple sclerosis (MS), but were not found in a model of relapsing-remitting MS (RRMS), according to researchers. These changes, seen before symptoms of the disease started, were…

Multiple Sclerosis News Today brought you daily coverage of the latest scientific findings, treatment developments, and clinical trials related to multiple sclerosis (MS) throughout 2020, a year marked by the COVID-19 pandemic. We look forward to reporting more news to patients, family members, and caregivers dealing with MS during…

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…

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 cerebrospinal fluid (CSF) of people with progressive multiple sclerosis (MS) contains elevated levels of specific fatty molecules that disrupt the energy “powerhouses” of nerve cells, and appear to underlie the neurodegeneration seen on brain scans of these patients, a study reveals. The research, which compared the CSF…

Editor’s note: Tamara Sellman continues her occasional series on the MS alphabet with the second of two columns about terms starting with the letter “M.” Symptoms of MS Marcus Gunn pupil This is a sign of emerging MS that may be discovered during what is known as the…

The online multiple sclerosis community GeneFo will hold a webinar next week to discuss the latest research findings on how mitochondrial antioxidants may affect MS. The webinar, which will be open to patients who register, will start at 1 p.m. U.S. Eastern Standard Time on Thursday, Aug. 24. GeneFo…

High levels of a protein called Rab32 may contribute to the progression of multiple sclerosis (MS), leading to neuronal loss, a new study concludes. The study, “Rab32 connects ER stress to mitochondrial defects in multiple sclerosis,” appeared in the Journal of Neuroinflammation. The endoplasmic reticulum (ER) is involved in the production…

GeneFo, a social-medical community that connects patients with multiple sclerosis (MS) and offers free in-house medical consulting, recently announced a partnership with MitoQ, a New Zealand-based company focused on mitochondrial health. MitoQ is a mitochondria-targeted antioxidant supplement that may help to alleviate common symptoms in MS. MS, a chronic disease of the central…

One June 3, a workshop titled “Metabolism in MS and Related Conditions” was presented at the 2016 Annual Meeting of the Consortium of Multiple Sclerosis Centers (CMSC), held June 1-4 in National Harbor, Maryland. One of the speakers was Dr. David Sheikh-Hamad, professor of medicine-nephrology at Baylor College of…

Scientists in recent years have wondered whether a link exists between high lactate levels resulting from mitochondrial dysfunction and multiple sclerosis (MS) progression. Now researchers in Italy showed that lactate, a metabolic byproduct, is indeed increased in the cerebrospinal fluid of MS patients and may be a disease driver. Mitochondria are the body’s energy factories,…

Multiple Sclerosis News Today has reported the latest therapies, clinical trial developments, and events in multiple sclerosis (MS) on a daily basis throughout the past year. As 2015 comes to an end, here are the year’s 10 articles most widely read by  Multiple Sclerosis News Today readers, each with a brief summary of the developments…

A research team recently showed that key enzymes of energy metabolism pathways are differentially expressed in active and inactive multiple sclerosis (MS) lesions, and may contribute to axonal degeneration in MS. The study, titled “Differential expression of glucose-metabolizing enzymes in multiple sclerosis lesions,” was published in the…

Recent attention to the role of mitochondria in the etiology of multiple sclerosis (what causes the disease) suggests that mitochondrial defects and mitochondrial structural and functional changes may contribute to the disease. Researchers studying mitochondria in multiple sclerosis believe abnormalities in mitochondrial dynamics impact cellular pathways such as inflammation and…

Researchers at United Arab Emirates University in Abu Dhabi have recently published in the journal BMC Neuroscience new insights into the involvement of mitochondria and energy metabolism in the pathology of multiple sclerosis (MS) in rats. The study is entitled “Bioenergetics of the spinal…
