Lead inhibition of NMDA channels in native and recombinant receptors
@article{Gavazzo2001LeadIO, title={Lead inhibition of NMDA channels in native and recombinant receptors}, author={P. Gavazzo and A. Gazzoli and M. Mazzolini and C. Marchetti}, journal={Neuroreport}, year={2001}, volume={12}, pages={3121-3125} }
NMDA channels are key targets for lead (Pb2+) neurotoxicity and Pb2+-induced inhibition of NMDA current is age- and subunit-dependent. In rat cerebellar granule cells maintained in high KCl, glycine affinity as well as sensitivity to ifenprodil change significantly with the days in vitro, indicating a reduction of NR2B subunit expression. Pb2+ blocked NMDA current with IC50 ∼4 μM and this effect decreased significantly during the second week in vitro. In Xenopus laevis oocytes expressing… CONTINUE READING
