1 The effects of BDNF on NMDA-activated currents were examined in greater detail. N-Methylaspartate brain-derived neurotrophic factor Rattus norvegicus
2 The enhancement of NMDA-activated currents by BDNF was observed using both perforated and whole cell patch recording techniques and could be demonstrated in outside-out patches. N-Methylaspartate brain-derived neurotrophic factor Rattus norvegicus
3 Modulation of NMDA responses by BDNF was dependent on the concentration of extracellular glycine. N-Methylaspartate brain-derived neurotrophic factor Rattus norvegicus
4 However, the competitive glycine-site antagonist 7-chloro-kynurenic acid blocked the enhancement by BDNF without shifting the dose-inhibition relationship for this antagonist, and Mg2+ consistently depressed the potentiation of NMDA-evoked currents by BDNF, indicating that BDNF does not alter glycine affinity. N-Methylaspartate brain-derived neurotrophic factor Rattus norvegicus
