Abstract

Hippocampal sclerosis is the most common pathology seen in drug-resistant patients. Besides specific alterations in neuronal populations, the epileptogenic hippocampus shows gliosis, which can impact tissue excitability and are linked with the increase in T2 signal and relaxation seen in the epileptogenic hippocampus. Despite the qualitative association between gliosis and T2 signal, quantitative studies failed to show this relationship. The hypothesis of the present proposal is that changes in several glial proteins linked with tissue homeostasis would reflect better the increased T2 signal than merely the intensity of gliosis, measured by GFAP and HLA-DR.
