Multiple sclerosis (MS) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) share similar symptoms but are two biologically distinct conditions, with different immune signatures, a study found. These findings help explain why treatments approved for MS generally show limited effectiveness for MOGAD, researchers said. “These findings support MOGAD as its…

Interactions between the body’s immune system and bacteria that live in the digestive tract — essentially, a person’s gut — become disrupted in multiple sclerosis (MS), a new study by U.S. researchers found. The human intestines are home to billions of bacteria and other microorganisms, collectively known as the…

Developing a more comprehensive understanding of the interactions between the brain, blood vessels, and the immune system holds great promise for unlocking new ways to treat neurological diseases like multiple sclerosis (MS), a team of researchers argued in a new commentary paper. “Interactions between the brain, blood vessels, and…

People with multiple sclerosis (MS) have elevated immune responses to more proteins of the Epstein-Barr virus (EBV) than previously thought, according to a new study. EBV-specific immune T-cells isolated from MS patients could also respond to multiple proteins found in the brain, particularly those associated with myelin,…

Two researchers from The University of Western Australia (UWA) have received grants from MS Australia for work that may help scientists better understand how an immune system gone awry can cause multiple sclerosis (MS). Belinda Kaskow, PhD, a teaching and research fellow at UWA’s School of Biomedical Sciences,…

Following an autologous hematopoietic stem cell transplant (aHSCT) in people with multiple sclerosis (MS), the population of “naïve” T-cells — components of the immune system that enable the body to fight off new, unrecognized infections — is completely renewed but some memory T-cells, which are responsible for rapid responses…

Researchers have identified four new brain proteins that are targeted by inflammatory T-cells in multiple sclerosis (MS), which could aid in the development of more specific and safer treatments for people with the condition. The study, “Identification of four novel T cell autoantigens and personal autoreactive profiles in…

My week is never exactly easy, but it’s much harder for my family. Not only do they have to deal physically with my ever-enlarging lump of flesh, there’s also my verbal diarrhea to contend with. Then last Tuesday, it wasn’t just the verbal kind. Turns out my bowels began to…

COVID-19 Booster May Benefit Patients on Anti-CD20 Therapy After multiple reports of how Gilenya and anti-CD20 MS medications reduce the efficacy of the mRNA COVID-19 vaccines, here’s more evidence that a booster shot may improve that protection. The researchers report “modestly increased levels” of anti–SARS-CoV-2 antibodies after a third…

Repertoire Immune Medicines and Yale University have entered a research collaboration to identify what type of antigens are activating immune T-cells in patients with multiple sclerosis (MS). Antigens are molecular structures, such as a portion of a protein or a specific chain of sugars, that trigger an immune…

A Phase 1 clinical trial investigating ANK-700 as a means to restore immune tolerance to myelin in people multiple sclerosis (MS) has begun dosing participants. Currently recruiting at a single site in Tennessee, the trial (NCT04602390) is expected to enroll up to 40 patients with relapsing-remitting…

Lately, I’ve seen a lot of incorrect information on social media about how multiple sclerosis affects our immune system. Some of it seems to be prompted by concerns that MS makes someone more susceptible to COVID-19, or confusion about whether people with MS can safely receive a COVID-19 vaccine. Here…

Lipid (fat) molecules can function as chemical couriers, taking messages from tissue to tissue, organ to organ as part of the body’s immune defense guidance system. But in certain diseases such as multiple sclerosis (MS), the courier service may go awry. One such lipid molecule, called sphingosine 1-phosphate (S1P),…

Childhood trauma can affect disease progression of multiple sclerosis (MS) and treatment in adulthood, a study in mice suggests. The study shows that mice that experienced early-life trauma were more likely to develop an autoimmune condition and less likely to respond to common treatment with interferon beta. The study,…

To fully understand autoimmune diseases like multiple sclerosis (MS), it is necessary to study not just the immune system, but also the tissue that the immune system is attacking, a study suggests. “We must move away from the present ‘immune-centric-only’ view of autoimmune diseases,” Decio Eizirik, MD, PhD, study…

A recently identified group of immune cells saved damaged nerve cells from death and promoted nervous system repair, a new study suggests. This finding may represent new promise for treating neurodegenerative diseases such as multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS). The study, “A new neutrophil…

Rituximab, an investigational B-cell depletion therapy that target CD20 to treat people with multiple sclerosis (MS), has significant effects on the characteristics of B-cells that return after treatment is stopped, with cells being less mature yet more activated toward a pro-inflammatory state, a study showed. Treatment also…

The U.S. Food and Drug Administration (FDA) has accepted an investigational new drug application (IND) for ANK-700, a treatment candidate for multiple sclerosis (MS) that is being developed by the Swiss company Anokion. With this approval, Anokion can enter clinical testing and is planning to…

A person infected through the skin by the hookworm Necator americanus shows a spike in  regulatory T-cells, specialized immune T-cells that work to limit inflammation, and a controlled infection by these generally safe worms may benefit some relapsing multiple sclerosis (MS) patients, research suggests. “The…

IC 100, a monoclonal antibody by ZyVersa Therapeutics that prevents the assembly of inflammasomes — a pro-inflammatory cellular complex — lessened inflammation and halted disease progression in multiple sclerosis (MS), a study of mice shows.xa The study, “IC100: a novel anti-ASC monoclonal antibody improves functional outcomes…

A subset of monocytes (a type of immune cells) that can infiltrate the central nervous system and drive nerve cell damage in multiple sclerosis (MS) may be a better target for preventing disease progression than the cells of the immune system that are currently targeted with MS therapies,…
