Testing for the types of fat (lipid) molecules present in the cerebrospinal fluid (CSF) of people with multiple sclerosis (MS) may be a very useful way to diagnose and monitor the disease, a study suggests. “MS patients present a different lipid profile at the time of diagnosis” than…

Scientists identified and “fingerprinted” a group of T-helper cells that are unusually numerous in the blood and central nervous system of people with relapsing-remitting multiple sclerosis (RRMS), and may be the reason behind the neuroinflammation seen in these patients. This T-cell population carries specific markers involved in the transmission…

Treatment with Ocrevus (ocrelizumab) decreases the levels of neurofilament light chain (NfL) and immune B-cells in the serum and central nervous system of patients with relapsing multiple sclerosis (MS), according to results from a Phase 3 trial. The research, “Ocrelizumab treatment reduced levels of neurofilament light chain and…

Quanterix is leading the research presented at this year’s American Academy of Neurology (AAN) Annual Meeting, validating the use of neurofilament light chain (NfL) as a potential biomarker for the diagnosis, prognosis, and treatment monitoring of patients with multiple sclerosis (MS) and other neurodegenerative diseases. The company…

Treatment with Tysabri (natalizumab) lowers the levels of the biomarker serum neurofilament light chain (sNfL) in patients with secondary progressive multiple sclerosis (SPMS), according to data from a Phase 3 trial. Findings also revealed that higher levels of sNfL correlated with MS lesions and disease activity prior to starting the…

High blood levels of a signaling protein known as TWEAK are associated with active neuroinflammation in patients with multiple sclerosis (MS), a study shows.
