Inhibition of Myelin-Cleaving Poteolytic Activities by Interferon-Beta in Rat Astrocyte Cultures. Comparative Analysis between Gelatinases and Calpain-II

摘要

BackgroundProteolytic enzymes have been implicated in the pathogenesis of Multiple Sclerosis (MS) for both their ability to degrade myelin proteins and for their presence in MS plaques.In this study we investigated whether interferon-beta (IFN-β) could differently modulate the activity and the expression of proteolytic activities against myelin basic protein (MBP) present in lipopolysaccharide (LPS)-activated astrocytes.
