Zn2+ , the second most prevalent trace element in the body, is essential for supporting a wide range of biological functions. While the majority of Zn2+ in the brain is protein-bound, a significant proportion of free Zn2+ is found co-localized with glutamate in synaptic vesicles and is released in an activity-dependent manner. Clinical studies have shown Zn2+ levels are significantly lower in blood and cerebrospinal fluid of children that suffer febrile seizures. Likewise, investigations in multiple animal models demonstrate that low levels of brain Zn2+ increase seizure susceptibility. Recent work provides human genetic evidence that disruption of brain Zn2+ homeostasis at the level of the ..
