To get insights on whether increased P-gp expression is a consequence of the initial insult, or evolves more gradually as a result of recurrent spontaneous seizures, we used a rat model of temporal lobe epilepsy in which spontaneous seizures develop after an electrically induced SE.
To the best of our knowledge, these are the first results to indicate that the RGMa‑FAK‑Ras pathway may be involved in MFS and the development of temporal lobe epilepsy.
EE treatment significantly, as well as improved cognitive impairments and decreased long-term seizure activity, and that these effects might be mediated through SDF-1/CXCR4 pathway during the chronic stage of TLE.
HCN1 and HCN2 expression were measured using in situ hybridization and immunocytochemistry in hippocampi from three groups: TLE with hippocampal sclerosis (HS; n = 17), epileptic hippocampi without HS, or non-HS (NHS; n = 10), and autopsy material (n = 10).
Enduring, abnormal expression and function of the ion channel hyperpolarization-activated cyclic adenosine monophosphate gated channel type 1 (HCN1) occurs in temporal lobe epilepsy (TLE).
We previously showed that patients with temporal lobe epilepsy (TLE) present an increased expression of angiotensin II (AngII) AT1 and AT2 receptors in the hippocampus, supporting the idea of an upregulation of renin-angiotensin system (RAS) in this disease.
In line with the findings from the rat model, expression of astrocytic ADK was also found to be increased in the hippocampus and temporal cortex of patients with TLE.
We used a pathophysiological model of temporal lobe epilepsy induced by pilocarpine in adult rats in order to assess the in vivo role of drebrin A (DA), one of the major regulators of F-actin.
Dysbindin was expressed in the cytoplasm of neurons from epileptic specimens, and levels of dysbindin proteins were significantly increased in patients with TLE.
These findings suggest that the transduction of dendritic Ca2+-signals via caldendrin is altered by epileptic seizures and that caldendrin might be involved in the pathophysiology of temporal lobe epilepsy.
Expression of brain specific chondroitin sulfate proteoglycans, neurocan and phosphacan, in the developing and adult hippocampus of Ihara's epileptic rats.
These results suggest that AK2 participates in the pathophysiological process of TLE and may be a marker for neuronal apoptosis induced by pathological injury in TLE.
