Functional properties of astrocytes were investigated with the patch-clamp technique in acute hippocampal brain slices obtained from surgical specimens of patients suffering from pharmaco-resistant temporal lobe epilepsy (TLE). In patients with significant neuronal cell loss, i.e. Ammon's horn sclerosis, the glial current patterns resembled properties(More)
Astrocytes and neurons are tightly associated and recent data suggest a direct signaling between neuronal and glial cells in vivo. To further analyze these interactions, the patch-clamp technique was combined with single-cell RT-PCR in acute hippocampal brain slices. Subsequent to functional analysis, the cytoplasm of the same cell was harvested to perform(More)
PURPOSE The specific role of glial cells in epilepsy is still elusive. In this study, functional properties of astrocytes were investigated in acute hippocampal brain slices obtained from surgical specimens of patients with drug-resistant temporal lobe epilepsy (TLE). METHODS The patch-clamp technique together with a single-cell reverse(More)
PURPOSE Recent data suggested a role for glial cells in epilepsy. This study sought to identify and functionally characterize AMPA receptors expressed by astrocytes in human hippocampal tissue resected from patients with intractable temporal lobe epilepsy. METHODS Patch-clamp and fast application methods were combined to investigate astrocytes in situ and(More)
Kainate-induced seizures increase hippocampal neurogenesis. Glial fibrillary acidic protein-positive astrocytes with radial processes in the dentate gyrus share many of the characteristics of radial glia and appear to act as precursor cells for adult dentate neurogenesis. Using the chemoconvulsant kainate and transgenic mice with human glial-fibrillary(More)
