| abstractText | Carbamazepine (CBZ) is a commonly used antiepileptic drug known to block voltage-gated sodium channels. Infants exposed to CBZ in utero show reduced head circumference, for reasons unknown. We investigated CBZ's effect on neural growth in megencephaly (mceph/mceph) mice lacking functional Kv1.1. Mice fed with CBZ were assessed for brain structure size, seizure behavior and expression of markers for neuronal plasticity and rescue in brain. CBZ counteracted brain overgrowth and the increased size of neurons in the mceph/mceph mouse. These effects of CBZ occurred at doses that did not fully suppress epileptic behavior. Furthermore, CBZ normalized Bdnf mRNA levels and mRNA species encoding Nogo signaling pathway proteins. In conclusion, CBZ protects efficiently against abnormal growth and abnormal expression patterns of nerve growth signaling systems in the mceph/mceph brain. These observations and the effect of CBZ in utero suggest that CBZ treatment might be advantageous in some types of human idiopathic megalencephaly. |
