Section of Biochemistry and Clinical Biochemistry, Department of Biochemistry and Molecular Biology, University of Ferrara, via Luigi Borsari 46, Ferrara I-44100, Italy Background Little is known about the involvement of matrix metalloproteinase-2 (MMP-2) and its tissue inhibitor TIMP-2 in multiple sclerosis (MS). Objective To elucidate the actual implication of MMP-2 and TIMP-2 in MS. Methods Cerebrospinal fluid (CSF) and serum levels of active MMP-2 and TIMP-2 were measured by activity assay system and ELISA, respectively, in 67 patients with relapsing–remitting MS (RRMS), categorized according clinical and magnetic resonance imaging (MRI), and in 129 controls. Results Cerebrospinal fluid and serum active MMP-2/TIMP-2 ratio mean values and an intrathecal active MMP-2 production were more increased in RRMS than in non-inflammatory conditions (P < 0.001, P < 0.05, and P < 0.0001, respectively) and in MRI inactive than in MRI active RRMS (P < 0.02, P < 0.01 and P < 0.001, respectively). An intrathecal synthesis of active MMP-2 was more frequent in RRMS than in inflammatory disorders (P < 0.01). Serum active MMP-2/TIMP-2 ratio and MS disease duration were positively correlated (P < 0.02). Conclusion These findings suggest a potential role for MMP-2 activity in the termination of MS neuroinflammation related to remission of the disease and seem to indicate that serum MMP-2/TIMP-2 ratio may represent a useful biomarker for monitoring MS recovery phase.
