calpain and Multiple-Sclerosis--Chronic-Progressive

This study examines the cytokine/chemokine profile of a 62-year-old African American male with progressive multiple sclerosis (MS). MRI images of the MS patient demonstrated generalized white matter involvement with multiple lesions in the periventricular area. A 42-plex Discovery Assay® (Eve Technologies) of the patient's plasma and peripheral blood mononuclear cells (PBMCs) supernatant or PBMC-derived T cell supernatant samples from two separate clinic visits revealed vastly differing cytokine/chemokine levels. In addition, certain cytokine/chemokine profiles had notable differences when compared to the larger patient group or patients' PBMCs treated with a calpain inhibitor in vitro. Interestingly, large numbers of cytokines/chemokines and growth factors in MS PBMCs are modulated by calpain inhibition, suggesting the clinical significance of these findings in designing better therapeutics against progressive MS.
