Resumen
Introducción: La epilepsia del lóbulo temporal (ELT) es el tipo más frecuente de epilepsia resistente a los fármacos en humanos. La necesidad de estudios invasivos y la resección de tejido permiten numerosos estudios acerca de su fisiopatología. Objetivos: Se revisan algunos de los datos y teorías más recientes sobre la fisiopatología de la ELT, haciendo especial referencia a la participación de la albúmina en la activación de los astrocitos tras la rotura de la barrera hematoencefálica (BHE). Se observa una remodelación de la excitación glutamatérgica y la inhibición gabaérgica que deriva en hiperexcitabilidad. Aunque se conocía desde hace tiempo la rotura de la BHE en la ELT, no se había asignado un papel a este aumento de permeabilidad. Recientemente, se demostró que dicha rotura permite el paso de la albúmina al espacio extracelular cerebral, activando los astrocitos por medio del receptor TGF-β, que sufren cambios en la expresión genética. Estos cambios podrían condicionar las modificaciones en la respuesta neuronal responsables de la hiperexcitabilidad. Conclusiones: El estudio multidisciplinario de la fisiopatología de la ELT en la última década nos ha permitido aumentar nuestro conocimiento sobre los procesos que subyacen a la génesis de las crisis, su clínica y evolución.

Abstract
Introduction: Temporal lobe epilepsy (TLE) is the most frequent form of pharmaco-resistant epilepsy in human. The necessity of invasive studies and epileptic tissue resection allow a number of studies pertaining to the pathophysiology. Objectives: Here, we review recent findings and theories pertaining to the pathophysiology of TLE, with special reference to astocyte activation by albumin after blood-brain barrier (BBB) increase in permeability. Data suggest that the common principle that appears to underlie the epileptic condition is the reorganization of excitation and inhibition resulting in hyperexcitability. From a long time, it had been observed an increase in permeability of BBB in epilepsy. However, no definitely role in the epileptogenesis had been ascribed to this disruption. Recently, it has been showed the BBB disruption allows that albumin goes into the extracellular space, activating astrocytes through TGF- receptor and inducing changes in gene expression. These changes can induce alterations in the neuronal response, underling the hyperexcitability. Conclusions: A multidisciplinary approach can help to fill gaps in our knowledge and to provide unique insights into the pathophysiology of TLE.
