AIM Astrocytes contribute to the maintenance of brain homeostasis via the release of gliotransmitters such as ATP and glutamate. Here we examined whether zinc was released from astrocytes under stress-loaded conditions, and was involved in the regulation of microglial activity as a gliotransmitter. MAIN METHODS Hypoosmotic stress was loaded to astrocytes(More)
To elucidate the regulatory mechanism for extracellular zinc in the CNS, we examined the zinc uptake characteristics in mouse astrocytes and microglia. Zinc was taken up into the two cell types time-dependently, and the cell-to-medium concentration (C/M) ratio in the initial uptake phase in astrocytes was significantly smaller than that in microglia, while(More)
