The coordinated activity of neuronal circuits underlies brain activity and aberrant changes occurring in those networks can result in seizures. Spontaneous seizures are the main features of epilepsy, a chronic disorder that affects over 65 million people worldwide. Although many anticonvulsant drugs with good effects on several patients are available, almost 30% of patient are resistent to pharmacological treatments. For these reasons, alternative therapies need to be developed.
Our laboratory has a great interest toward the comprehension of the mechanisms underlying the development of the cerebral cortex and in particular of GABAergic interneurons, the neuronal population accounting for inhibition in this compartment of the brain. Alterations in the activity of GABAergic interneurons cause an unbalance between excitation and inhibition in the cerebral cortex, ultimately leading to seizure onset. We are now employing our knowledge in the development of interneurons to exploit new gene therapy and cell therapy approaches for the treatment of drug resistant epileptic encephalopathies.
