Abnormal Neurons Associated With Epilepsy Normalized by Optimal Modulation of Ion Channels
The study, published by Cell Press in the October 18th issue of Biophysical Journal, describes a procedure that may be useful for rescuing function in organs with excitable cells, such as the heart and pancreas.
Ion channels regulate the flow of ions into and out of the cell and are absolutely critical for a wide range of biological processes, including transmission of signals in the nervous system. Disrupting ion channel function can have disastrous consequences. For example, the severe neurological disorder epilepsy is characterized by spontaneous and recurrent seizures that are thought to be linked with ion channel dysfunction.
Dr. Erik Fransén from the Royal Institute of Technology in Stockholm was interested in examining neuronal excitability at the single-cell level and using sophisticated computational modeling to discover a way to restore normal neuronal function. "We studied ion channel alteration related to epilepsy," explains Dr. Fransén. "Previously, we showed that dysfunction of a specific potassium channel, KA, was linked to synchronicity, one of the key elements of epilepsy. In this current study, we focused on improving the functional behavior of the neuron and reversing pathological changes."
Dr. Fransén and colleagues studied the modulation of KA by substances known to influence channel activation. Sophisticated ion channel simulations allowed the researchers to examine known modulatory substances and to determine the most beneficial concentration of the modulators for reduction of abnormal neuron activity. Importantly, the optimization method revealed specific combinations of modulators that reversed pathological changes in KA observed in a patient with epilepsy.
