A common virus that causes cold sores, herpes simplex virus type 1 (HSV-1), may contribute to multiple sclerosis (MS). That’s according to a study by researchers at the University of Illinois Chicago (UIC). In mice lacking a protein that helps control HSV-1, infection led to the degradation of the…

A small molecule that blocks the activity of a protein called TYK2 in the brain showed promise at reducing disease activity in mouse models of multiple sclerosis (MS), according to a study. The study was conducted by Neuron23, which is advancing a small molecule TYK2 inhibitor called NEU-627…

Blocking the activity of a protein called connexin 43 (Cx43) may be an effective strategy to treat multiple sclerosis (MS), according to a recent study in animal models of the disease. A compound called INI-0602, which was designed to inhibit this protein, significantly eased disease severity in mice, including…

Blocking the activity of a protein complex called the NLRP3 inflammasome lessened disease severity in a mouse model of multiple sclerosis (MS), a study reports. Results point to NLRP3 as a promising target to ease inflammation in people with MS, but additional studies will be needed to determine the…

In a surprise discovery, researchers found that deleting a protein called integrin alpha-3 blocked harmful immune cells from accessing the brain — and prevented the onset of symptoms — in a mouse model of multiple sclerosis (MS). Now, the researchers say that targeting this protein might be one way…

Attaching a kind of molecule backpack to myeloid cells — a type of immune cells involved in the inflammatory attack that drives multiple sclerosis (MS) — may help to halt inflammation and damage in the brain in MS by modulating immune cell activity, a study…

The body has two distinct lineages of immune cells that can be distinguished by the presence or absence of the vitamin D receptor, a preclinical study reports. The findings shed more light on how vitamin D fine-tunes immune responses and may help researchers better understand the link between vitamin…

Researchers have developed a technique that uses CAR T-cells, a form of cell therapy, to specifically eliminate the self-reactive immune cells that drive multiple sclerosis (MS), without destroying healthy immune cells needed to protect against infection. “Our CAR-T cells were very effective at treating mice that have an MS-like…

A team of researchers has discovered that the key to bypassing the blood-brain barrier — a semipermeable border that protects the brain against toxins in the blood but also blocks potential treatments — is the Unc5B receptor in the endothelial cells that line the tiny blood vessels in the brain.

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.

A matrix protein called fibulin-2, which is increased in multiple sclerosis (MS) lesions, blocks the activity of oligodendrocytes, the cells responsible for making myelin. Blocking this protein may be a promising approach to restore myelin in people with the neurodegenerative disease, a study in mice showed. The data was…

Certain cell therapies that hold promise for treating autoimmune diseases like multiple sclerosis might work not because of the way the cells live in the body during treatment, but because of how they die. A better understanding of how these cell therapies work “is important in designing treatment protocols…

A team of scientists is working on a new delivery method that would use tiny capsules for getting cannabidoil, or CBD, to the brain. According to a study in mice, microcapsules containing cannabidiol can be combined with vesicles carrying a bile acid — an acid found in the gut —…

The enzyme TET1, which is progressively lost with age, is essential to activate genes needed to repair myelin — the sheath around nerve cells that is damaged in people with multiple sclerosis (MS) — a study in mice has found. The…

Editor’s note: The Multiple Sclerosis News Today news team is providing in-depth and unparalleled coverage of the virtual ACTRIMS Forum 2021, Feb. 25-27. Go here to see all the latest stories from the conference. Factors in the cerebrospinal fluid (CSF) surrounding the brain and spinal cord change with age and can affect…

Researchers have created a detailed map of the mouse nervous system, including the location of the many diverse cell types in the brain, in the largest study yet of the makeup of the mammalian nervous system.  The new map could provide new clues about the origin of neurological…
