Generation of three induced pluripotent stem cell (iPSC) lines from a patient with developmental epileptic encephalopathy due to the pathogenic KCNA2 variant c.869T>G; p.Leu290Arg (NUIGi052-A, NUIGi052-B, NUIGi052-C).

De novo pathogenic variants in KCNA2 are implicated in causing a spectrum of human neurological disorders, in particular developmental and epileptic encephalopathies. KCNA2 encodes the voltage-gated delayed rectifier potassium channel K1.2, which is vital in regulating neuronal membrane potential and repolarization.

The Isotropic Fractionator as a Tool for Quantitative Analysis in Central Nervous System Diseases.

One major aim in quantitative and translational neuroscience is to achieve a precise and fast neuronal counting method to work on high throughput scale to obtain reliable results. Here, we tested the isotropic fractionator (IF) method for evaluating neuronal and non-neuronal cell loss in different models of central nervous system (CNS) pathologies. Sprague-Dawley rats underwent: (i) ischemic brain damage; (ii) intraperitoneal injection with kainic acid (KA) to induce epileptic seizures; and (iii) monolateral striatal injection with quinolinic acid (QA) mimicking human Huntington's disease.
