Novel biomarkers in development for MS
August 14, 2023Neurofilament-light chain (NfL) and glial fibrillary acidic protein (GFAP) are two of the main fluid biomarkers currently being examined for their clinical utility in evaluating disease activity, progression and treatment response. However, there are a number of other biomarkers under investigation. The following is a summary of some of the more promising candidates (reviewed in Maroto-Garcia et al.
