In neurological inflammatory conditions like multiple sclerosis (MS), inflammatory immune cells may enter the brain through arachnoid cuff exit (ACE) points — newly discovered structures that normally seem to serve as a type of sewer system in the brain, helping to move out waste. Figuring out exactly how immune…

Ocrevus (ocrelizumab) did not significantly reduce the number or volume of inflammatory lesions in the meninges in people with multiple sclerosis (MS), according to a recent pilot study. While inflammation in the meninges, the protective membranes that surround the brain and spinal cord, is thought to be driven…

A team of researchers has created a three-dimensional (3D) map of the lymphatic vessels that drain the brain, and demonstrated that these vessels are organized similarly in mice and in humans. The researchers propose measuring these vessels using MRI scans could “allow longitudinal imaging of disease progression that may be…

With the help of 7 Tesla magnetic resonance imaging (MRI), investigators discovered that leptomeningeal enhancement — a radiographic finding indicative of brain inflammation — is more common than previously thought in people with relapsing-remitting multiple sclerosis (RRMS), and is tied to lesions in specific regions of the brain.

Treatment with Mayzent (siponomod) may reduce myelin deterioration by lessening the accumulation of immune cells in brain meninges, and preventing the migration of pro-inflammatory lymphocytes into the brain, according to a study in a mouse model of multiple sclerosis (MS). The research, “A Mouse Model of…

A method based on cerebrospinal fluid measurements and magnetic resonance imaging (MRI) can aid in stratifying patients with multiple sclerosis (MS) at the time of diagnosis, which may help identify a tailored therapeutic approach for each patient from early disease stages. The data was presented by Roberta Magliozzi, from…

Lymphatic vessels, the “roads” that work to clear waste material from the brain, can also carry messages that direct immune system attacks against myelin, promoting the onset of multiple sclerosis (MS), new study shows. While the identity of these messages remains unknown, the findings suggest that blocking these signals could…

The discovery of a new type of immune cell in the membranes covering the brain is likely to advance understanding of the immune system’s impact on the brain, a study says. It could also lead to new treatments for multiple sclerosis (MS) and other neurodegenerative diseases. Researchers knew the immune…

Researchers have found neural stem cells (immature cells that can become neurons) in the meninges of the brain, a three-layer structure that protects the nervous system, according to results of a new study. The discovery of this pool of stem cells in the adult brain opens new possibilities for the…

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…

An exciting new discovery has turned the medical world upside down, and could have important implications for the treatment of multiple sclerosis (MS). It turns out that previously undiscovered vessels exist that connect the nervous system and immune system directly. The study, titled “Structural and functional features…
