Web14 de abr. de 2009 · Taken together, these results suggest that OLG lineage cells release BDNF, a molecule trophic for proximate neurons. BDNF release is regulated by glutamate acting through mGluRs (metabotropic glutamate receptors) and the PLC pathway. Thus glutamate and BDNF may be molecules that support neuron–OLG interactions in the cortex. Webrinic receptors the metabotropic class. Glutamate, GABA, acetylcholine, and many other ligands activate both metab-otropic and ionotropic receptors [1]. With one exception, all receptors for dopamine(DA),serotonin(5-hydroxytryp-tamine, 5-HT), and norepinephrine are metabotropic receptors. The five metab-otropic DA receptors (D1–D5) in the CNS
