Query: A natural marmoset model of genetic generalized epilepsy. As a common neurological disease, epilepsy has been extensively studied. Efforts have been made on rodent and other animal models to reveal the pathogenic mechanisms of epilepsy and develop new drugs as treatment. However, the features of current epilepsy models cannot fully mimic different kinds of epilepsy in human, asking for non-human primates models of epilepsy. The common marmoset (Callithrix jacchus) is a New World monkey that is widely used to study brain function. Here, we show a natural marmoset model of generalized epilepsy. In this unique marmoset family, generalized epilepsy was successfully induced by handling operation in some individuals. We mapped the marmoset family with handling-sensitive epilepsy and found that epileptic marmoset had an autosomal dominant genetic predisposition. Those marmosets were more sensitive to epilepsy inducers pentylenetetrazol (PTZ). By electrocorticogram (ECoG) recording, we detected epileptic discharge in marmoset with history of seizures. However, there was no significant change in the overall structure of epileptic marmoset brain. In summary, we report a family of marmosets with generalized seizures induced by handling operation. This epileptic marmoset family provides insights to better understand the mechanism of generalized epilepsy and helps to develop new therapeutic methods.

Short summaryDespite the rodent and other animal models on epilepsy, a common neurological disease, the understanding of the pathogenic mechanisms of epilepsy and treatment are yet to be advanced., Non-human primates are good experimental animals for modelling neurological disease. Here we report a common marmoset family with generalized epilepsy induced by handling stimulation. We mapped the epileptic marmoset family and found that epilepsy had a genetic predisposition. The present report deals in detail with the phenotypes and characteristics of epileptic marmosets. This natural marmoset reflect epilepsy model will help to better understand the mechanism of epilepsy and develop new therapeutic methods.
