Zinc in the physiology and pathology of the CNS

Sensi, Stefano L., Paoletti, Pierre, Bush, Ashley I., Sekler, Israel·2009·Nature Reviews Neuroscience

Abstract

The past few years have witnessed dramatic progress on all frontiers of zinc neurobiology. The recent development of powerful tools, including zinc-sensitive fluorescent probes, selective chelators and genetically modified animal models, has brought a deeper understanding of the roles of this cation as a crucial intra- and intercellular signalling ion of the CNS, and hence of the neurophysiological importance of zinc-dependent pathways and the injurious effects of zinc dyshomeostasis. The development of some innovative therapeutic strategies is aimed at controlling and preventing the damaging effects of this cation in neurological conditions such as stroke and Alzheimer's disease.

  • High concentrations of zinc are present in synaptic vesicles of specific neurons, called 'zinc-containing' neurons, where it has a major role in controlling synaptic excitability by modulating neurotransmission mediated by both glutamate and gamma-aminobutyric acid.

  • Zinc is potently neurotoxic and could increase neuronal death during transient global ischemia and brain trauma, but neurons have numerous homeostatic systems to maintain zinc concentrations at levels that are nontoxic.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
