Extracellular matrix components are altered in the hippocampus, cortex, and cerebrospinal fluid of patients with mesial temporal lobe epilepsy

Epilepsia. 2002:43 Suppl 5:159-61. doi: 10.1046/j.1528-1157.43.s.5.30.x.

Abstract

Purpose: This work studied the profile of glycosaminoglycans (GAGs) in the hippocampus, cortex, and cerebrospinal fluid of patients with temporal lobe epilepsy (TLE).

Methods: The GAGs were analyzed by agarose gel electrophoresis, enzymatic degradation, and enzyme-linked immunosorbent assay (ELISA).

Results: The hippocampus of TLE patients showed increased levels of chondroitin sulfate and hyaluronic acid against normal levels of these GAGs in the neocortex and cerebrospinal fluid (CSF).

Conclusions: These results suggest that these matrix components could be involved in the pathophysiology of TLE.
