Th17 cells

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…

A protein called nephronectin mediates autoimmunity in a mouse model of multiple sclerosis (MS), and blocking this protein was found to prevent disease progression and processes that drive T-cells toward an inflammatory state, researchers reported. Study findings support nephronectin, a protein involved in kidney development, as a promising treatment…

A four-protein complex, or tetramer, of the protein STAT5 is involved in the development of multiple sclerosis (MS)-like autoimmune disease in mice, a new study shows. The findings point to this protein complex and its signaling pathway as a potential treatment in MS and other autoimmune conditions, scientists noted.

Pro-inflammatory T helper 17 cells, known as Th17 cells — a type of immune cell known to play a role in multiple sclerosis (MS) — directly interact with myelin-producing cells, promoting their damage and death, according to a study in a mouse model of MS and in samples from…

Vesicles containing the chemotherapeutic agent doxorubicin can be used to destroy the aberrant, myelin-damaging immune cells that contribute to multiple sclerosis (MS), suppressing the progression of the neurodegenerative disorder, according to recent research findings using a mouse model. If further validated, this technique could provide physicians with a new…

Due to differences in sex chromosomes, certain immune cells cause more severe disease in males than females, according to a new study in a mouse model of multiple sclerosis (MS). The findings could help to explain why biological males with MS tend to have more severe disease. The study,…

Scientists developed a new therapy for multiple sclerosis (MS) that prevents immune cells from exiting the lymph nodes and entering the spinal cord of mice with experimental autoimmune encephalomyelitis (EAE) — a condition that mimics MS in humans. The therapy, which consists of a…

Regulatory T-cells (Tregs) — immune cells that normally dampen immune and inflammatory responses by inhibiting the activity of pro-inflammatory immune cells — enabled mice in a model of multiple sclerosis to partly recover from limb and tail paralysis, scientists reported. Tregs can do this by preventing a subtype of…

Two specific bacteria present together in the gut led to more immune attacks on myelin and harsher symptoms in a mouse model of multiple sclerosis (MS). These findings add to existing evidence supporting the link between gut microbiota and MS, and highlight the need to consider potential combined effects of these…

A short-chain fatty acid produced by gut bacteria helps to counteract inflammatory responses in multiple sclerosis (MS) by promoting greater numbers of regulatory immune cells, a study reports. But the bacterial composition of the gut (its microbiome) of MS patients is deficient in bacteria that produce this acid —…

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 “…

Ofatumumab Better at Easing Relapse Rates and Slowing MS Progression Than Aubagio, Phase 3 Data Show Ofatumumab isn’t approved as a multiple sclerosis (MS) treatment. It’s a cancer medication that’s marketed as Arzerra. But in two clinical trials reported here, it did better than Aubagio at treating MS. Its…

Scientists may have found a way to manipulate T-helper 17 (Th17) cells so as to lower their ability to trigger inflammation, delaying the onset of multiple sclerosis (MS) in a mouse model and slowing its progression without affecting the entire immune system. Their findings may lead to new treatments with fewer…

An altered metabolism and signaling is associated with the ability of a subset of immune T helper 17 (Th17) cells to induce neuroinflammation, according to a new study of mice. The findings may lead to new treatments for multiple sclerosis (MS) and other chronic inflammatory diseases, the scientists said.

The pro-inflammatory Th17 cells that characterize multiple sclerosis (MS) may also underlie symptoms of obsessive-compulsive disorder (OCD), results of a mouse study show. The study, “Auto-Reactive Th17-Cells Trigger Obsessive-Compulsive-Disorder Like Behavior in Mice With Experimental Autoimmune Encephalomyelitis,” was published in the journal Frontiers in Immunology. “For the first time,…

Statistics show that men are three times less likely than women to develop multiple sclerosis. Research has shown that men also develop MS at a later age than women and that their disease is more progressive. Could this all be related to “low T,” or low testosterone? Researchers…

A stressful microenvironment, characterized by low metabolites and low oxygen levels, triggers the generation of immune cells directly implicated in a variety of inflammatory diseases, such as multiple sclerosis (MS). The study, “Cellular Stress in the Context of an Inflammatory Environment Supports TGF-β-Independent T Helper-17 Differentiation,” was…

New evidence strengthens the link between a diet high in salt and multiple sclerosis (MS) development, researchers show. The study, “Sodium Chloride Intake and MS,” was presented on Feb. 24 at the ACTRIMS) 2017 Forum being held in Orlando, Florida, by Dr. David Hafler with the Yale School of Medicine. The…

Paeoniflorin (PF), a herb component used in Chinese medicine, improved symptoms and reduced inflammation in a mouse model that recapitulates the human features of multiple sclerosis (MS). The study, “Paeoniflorin Ameliorates Experimental Autoimmune Encephalomyelitis via Inhibition of Dendritic Cell Function and Th17 Cell Differentiation”, appeared in the journal…

Researchers found that blocking a protein, known as integrin alpha 8, may work to prevent inflammation in the central nervous system of patients with multiple sclerosis (MS). The results were revealed in an oral presentation, “Integrin alpha8 is a novel mediator of T lymphocyte migration across the CNS barriers,” at the 32nd Congress of the European Committee…

Immune cells, believed to drive autoimmunity, are selectively increased in the gut of patients with multiple sclerosis (MS), along with lower numbers of cells controlling inflammation, suggesting that immune processes in the gut impact MS disease mechanisms. The study, “The role of gut immunity in multiple sclerosis patients,”…

At the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum 2016, being held from Feb. 18–20 in New Orleans, LA, researchers have gathered to discuss “Progressive MS: Bench to Bedside and Back,” the meeting’s theme. Secondary progressive multiple sclerosis (SPMS) is one of four types of MS, and is…

Results from a small pilot study indicated that high-dose vitamin D supplementation is safe and tolerable in patients with multiple sclerosis (MS), and that it can reduce the presence of autoimmunity-causing immune T cells. Patients are now being recruited for a larger clinical trial. The study, entitled “Safety and immunologic…

In a new study, researchers from the University of Toronto, Canada, uncovered the process behind the formation and maintenance of tertiary lymphoid tissues (TLTs), structures found in the meninges in the brains of multiple sclerosis (MS) patients. Their findings, reported in the article “Integration of Th17- and Lymphotoxin-Derived Signals Initiates…

Researchers demonstrated a process that prevented an induced autoimmune disease from taking hold in the central nervous system of mice, and think it has the potential of being translated into a multiple sclerosis (MS) therapy. The study detailing the method and its promising results is entitled “Infusion of Sulfosuccinimidyl-4-[N-maleimidomethyl]cyclohexane-1-carboxylate-Conjugated MOG35–55-Coupled…

New research at the University of Adelaide, Australia, may help pave the way toward the potential inhibition of multiple sclerosis (MS) and other autoimmune diseases. The study entitled “CCR2 defines in vivo development and homing of IL-23-driven GM-CSF-producing Th17 cells” was published in the journal …
