T-cell changes reflect pregnancy’s protective effects in MS

Changes in the gene activity within immune T-cells explain why women with multiple sclerosis (MS) improve during pregnancy, a study reports. Gene activity changes during and after pregnancy were highly similar between MS patients and healthy women. Many of the genes whose activity was altered during pregnancy were associated…

T-cells Targeting Epstein-Barr Virus at High Levels in MS Patients

People with multiple sclerosis (MS) have significantly more T-cells equipped with receptors that specifically recognize the Epstein-Barr virus (EBV) than do healthy individuals, a study revealed. Notably, no such differences were detected for T-cells with receptors specifically against other viruses. These findings add to previous data highlightingĀ EBV infection…

TRE-515 Appears to Block Immune Cell Attacks in Mouse Study

An experimental oral therapy called TRE-515 significantly reduced disease severity and the growth of the abnormal immune cells that drive multiple sclerosisĀ (MS) in two mouse models of the disease, a study found. Notably, the efficacy of Trethera Corp.ā€™s potential treatment, administered either in a preventive or therapeutic…

T-cells in Bone Marrow Work to Drive Inflammatory MS Attacks

Unusual growth in anĀ immune cell classĀ called myeloid cells is evident in the bone marrow of people with multiple sclerosis (MS), and these cells likely contribute to the inflammation that drives the disease, according to a new study. Experiments in mice suggest that myelin-reactive T-cells can migrate to the bone…

Study Finds New Molecules Targeted by the Immune System

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…

Researchers Identify Subset of Immune Cells Driving MS

A new subset of type 3 innate lymphoid cells (ILC3s) ā€” a type of immune cell known mostly for its anti-inflammatory and immunosuppressive effects in the gut ā€” infiltrates the brain and promotes the abnormal immune attacks that drive multiple sclerosisĀ (MS), according to a study in a mouse model…

Sugar Molecules in Yeast Cells Prevent Inflammation in Mouse Model

A component of yeast cell walls ā€” called MGCP ā€” prevented disease in a mouse model of multiple sclerosis (MS) by activating anti-inflammatory immune T-cells while suppressing inflammatory T-cells, a study showed. This work also supporting the microbiomeā€™s role in affecting inflammation in autoimmune diseases like MS. “We have…

Repertoire, Yale Working to Identify T-cells Driving MS

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

#AANAM ā€“ Exploring Mavenclad’s Effects on Immune Cells

Editorā€™s note: TheĀ Multiple Sclerosis News TodayĀ team is providing in-depth coverage of the 2021 Virtual AAN Annual Meeting, held April 17ā€“22. GoĀ hereĀ to read stories from the conference. After starting treatment with the multiple sclerosis (MS) therapy Mavenclad (cladribine), some types of immune cells are more affected…

Helper T-cells Drive Transition from RRMS to SPMS, Study Suggests

A group of helper T-cell (Th cells), a type of immune cell, could be responsible for the transition from relapsing-remitting multiple sclerosis (RRMS) to secondary progressive multiple sclerosis (SPMS), with important implications for diagnosing and treating SPMS, a new study found. The study, ā€œInvolvement of cytotoxic Eomes-expressing…

Dosing Begins in Trial of Anokion’s ANK-700 for RRMS

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…

Lipid Signaling Molecule Regulates Immune Responses in Mice

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),…
