We have tested the possibility that arachidonic acid may directly interact with the NMDA receptor by examining the ligand binding to this receptor/channel complex in hippocampal membrane preparation. Micromolar concentrations of arachidonic acid significantly increased both the association and dissociation of [3H]TCP binding but had no effect on the pre-equilibrated [3H]TCP binding. Arachidonic acid had no effect on the Kd and Bmax of [3H]TCP binding. Arachidonic acid also had no effect on the NMDA-displaced [3H]glutamate binding and [3H]glycine binding. In addition, docosahexanoic acid (DHA) potentiated [3H]TCP binding with similar features. However, oleic acid did not affect [3H]TCP binding. This study indicates that arachidonic acid potentiates the NMDA receptor-mediated response by directly increasing the activation of NMDA receptor-gated ion channel. ------>tmu_sno=None ------>sno=5222 ------>authors2=None ------>authors3=None ------>authors4=None ------>authors5=None ------>authors6=None ------>authors6_c=None ------>authors=Yeh, G.C., Wang,S.M. and Wang, I.F. ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c=None ------>publish_area=None ------>updateTitle=Interaction of arachidonic acid with ligand binding sites of the N-methyl-D-aspartate receptor in rat hippocampal membranes. ------>language=2 ------>check_flag= ------>submit_date= ------>country=None ------>no=2 ------>patent_SDate=None ------>update_bywho= ------>publish_year=1995 ------>submit_flag= ------>publish_month=None |
