The Role of the FCRL5 Protein in the Pathophysiology of Multiple Sclerosis and Response to Treatment
2026年8月24日 更新者：Université Catholique de Louvain
Multiple sclerosis (MS) is a chronic inflammatory and neurodegenerative disease of the central nervous system (CNS) and the leading non-traumatic cause of neurological disability in young adults.
Historically considered a T-cell-mediated disease, the paradigm for MS has shifted thanks to the efficacy of therapies targeting B cells.
The investigators recently identified FCRL5 as a B-cell-specific biomarker that is significantly elevated in the cerebrospinal fluid (CSF) of patients with relapsing-remitting MS and is independently associated with an increased risk of developing new MRI lesions within two years of diagnosis (ref.
Deltombe et al., PMID: 41004694).
This project aims to further explore FCRL5 as a prognostic biomarker, study the role of FCRL5-expressing B cells in MS pathogenesis and the effects of disease-modifying therapies on these subsets.
