Summary
Zinc is essential for brain health, acting as a neuromodulator and impacting cognitive function. Aberrant zinc levels are linked to neurological diseases, highlighting its critical role in central nervous system function.
Area of Science:
- Neurobiology
- Trace Element Metabolism
- Cellular Signaling
Background:
- Zinc is a vital trace element crucial for brain development and function.
- Zinc ions play roles in synaptic transmission, cortical plasticity, and neuromodulation.
- Dysregulation of zinc is implicated in various neurological and psychiatric conditions.
Purpose of the Study:
- To provide an overview of zinc neurobiology.
- To review evidence linking zinc signals to neuropsychiatric disease pathophysiology.
- To explore the therapeutic potential of targeting zinc homeostasis.
Main Methods:
- Review of existing literature on zinc's role in the central nervous system.
- Analysis of experimental evidence implicating zinc in neurological disorders.
- Discussion of zinc's dual role as essential nutrient and potential neurotoxin.
Main Results:
- Zinc is stored and released by specific glutamatergic neurons, influencing cognitive and emotional functions.
- Zinc dyshomeostasis is associated with neuronal injury in conditions like Alzheimer's disease and epilepsy.
- Zinc signaling is implicated in the pathophysiology of several neuropsychiatric diseases.
Conclusions:
- Zinc homeostasis is integral to normal central nervous system functioning.
- Understanding zinc's neurobiological roles may reveal new therapeutic targets for neuropsychiatric disorders.
- Aberrant zinc signaling is a significant factor in disease pathogenesis.

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...
