Abstract
A substrate conversion assay was used to detect gelatinase activity in the cerebrospinal
fluid (CSF) of patients with various neurological disorders. Two main forms of gelatinase
with an apparent molecular mass of 65 and 85 kDa, respectively, could be discerned.
The high molecular mass gelatinase was detectable only in samples of patients with
multiple sclerosis or other inflammatory neurological disorders. A statistically significant
correlation was found between the level of the 85-kDa gelatinase and the CSF cytosis.
This protease could play a role in the process of demyelination and breakdown of the
blood-brain barrier in certain neurological disorders, such as multiple sclerosis.
