| M K Shelton, K D McCarth. Mature hippocampal astrocytes exhibit functional metabotropic and ionotropic glutamate receptors in situ. Glia. vol 26. issue 1. 1999-05-13. PMID:10088667. |
in previous studies, neither metabotropic nor ionotropic glutamate receptor-mediated responses were detected by imaging ca2+ in astrocytes from mature (p21-p42) animals, suggesting astrocyte glutamate receptors only contribute to hippocampus physiology during development. |

astrocyte glutamate transporters are highly temperature sensitive, because l-glutamate-activated, anion-potentiated transporter currents in outside-out patches from these cells exhibited larger amplitudes and faster kinetics at 36 degreesc than at 24 degreesc. |

these findings indicate that in rat cerebellar tissue slices: (i) glutamate specifically modulates oligodendrocyte but not astrocyte development through selective activation of alpha -amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors, and (ii) cell depolarization and blockage of voltage-dependent k+ channels is likely to be the triggering mechanism. |

in fact, (1) the k+-induced [ca2+]i increases in astrocyte [ca2+]i were potently reduced by alpha-methyl-4-carboxyphenylglycine, a metabotropic glutamate receptor competitive inhibitor; (2) after emptying intracellular ca2+ stores with cyclopiazonic acid, none of the astrocytes displayed a [ca2+]i increase on the depolarizing stimulus; and (3) after inhibiting neurotransmitter secretion in neurons by incubating the slices with tetanus neurotoxin, no [ca2+]i increase on k+ stimulation was observed in astrocytes. |
