Chitinase-3-like 1 (CHI3L1) is a glycoprotein produced by monocytes, microglia and activated astrocytes that has been proposed as a diagnostic and prognostic biomarker of progression in MS. A recent meta-analysis of 20 studies reported that CHI3L1 levels in CSF were strongly correlated with the clinical course (Floro et al. Neurol Neuroimmunol Neuroinflamm 2022;9:e1164). Levels were higher in converting clinically isolated syndrome (CIS) vs. non-converting CIS; in MS vs. CIS or healthy controls; and in PPMS vs. RRMS. Read More

sNfL a biomarker of future disease activity: APLIOS
April 12, 2023Periodic assessment of serum neurofilament-light chain (sNfL) may be useful to identify subclinical disease activity, according to an analysis from the APLIOS study (Bar-Or et al. Neurol Ther 2023;12:303-317). Read More
