Inhibitory effects of methysergide bimaleate on the collagenase of the Clostridium histolyticum have been established. Having previously shown the inhibitory action of serotonin on this bacterial collagenase, the authors have tested methysergide bimaleate as another inhibitor. After injection in the peritoneum of the rats of methysergide bimaleate and collagenase together, lesions are minimal or absent, in contrast with the dramatic effects of collagenase alone. This shows the antagonist role of methysergide bimaleate in regard to collagenase and suggest that methysergide bimaleate reduce the collagenolysis and may elucidate the possible occurrence of fibrotic lesions after treatment of migraine by methysergide bimaleate in man.

Matrix metalloproteinases (MMPs) are zinc-dependent enzymes involved in remodeling extracellular matrix and cell-matrix interactions. A pathogenic role of MMPs in neurological disorders is likely. This paper focuses on serological clinical aspects only. In multiple sclerosis, higher serum MMP-3 is seen during relapses. Lower serum MMP-8 and -9 levels correlate with fewer contrast-enhanced T(2)-weighted MRI lesions, and serum MMP-9 can be used in monitoring treatment. In myasthenia gravis, serum MMP-2, -3, and -9 levels are elevated in both generalized and ocular diseases. A proportion of the patients have markedly increased serum MMP-3. In acute stroke, higher serum MMP-9 correlates with larger infarct volume, stroke severity, and worse functional outcome, and serum MMP-3 is significantly lower than in several other neurological disorders and healthy controls. In amyotrophic lateral sclerosis, serum MMP-2 correlates with disease progression, and both serum MMP-1 and -2 are elevated. In Alzheimer's disease, serum MMP-3, -9, and -10 are elevated. In migraine, serum MMP-2 is elevated, and also MMP-9 in those patients with migraine without aura. MMP-9 is implicated in the pathogenesis of experimental epilepsy. A pathogenic role of MMPs in these conditions could be related to their ability to degrade extracellular matrix. MMPs may also facilitate autoimmunity.
