Effect of neural precursor cell transplantation on anxiety and epileptic seizures


Epilepsy is characterized by spontaneous and recurrent seizures that develop from certain areas of the central nervous system (Dichter, 1997). Paroxysmal neuronal activity may be generated by defects in surrounding inhibition. Therefore, dysfunction or loss of GABAergic interneurons might play an important role in the development of epilepsy or behavioral disorders, such as anxiety that appeared as a co-morbidity of epilepsy (Vazquez e Devinsky, 2003; Perini e Mendius, 1984; Altshuler et al, 1990). Recent studies have shown that neuronal precursor cells from mesial ganglionic eminence (MGE) have the ability to migrate and to differentiate into functional inhibitory interneurons after transplanted in the mouse brain (Álvarez-Dolado et al., 2006). Thus, transplantation of neuronal precursor cells derived from MGE into the postnatal central nervous system could modify the neuronal circuitry involved in neurological diseases in which inhibitory synaptic function is altered, such as epilepsy and anxiety. The aim of this project is to evaluate the effects of MGE transplanted cells on anxiety and seizure susceptibility. (AU)
