...Juan Huang; Ekaterina F. Hult; Elisabeth Marchal; Stephen S. Tobe ABSTRACT The NMDA receptor (NMDAR) plays important roles in excitatory neurotransmission and in the regulation of reproduction in mammals. NMDAR in insects comprises two subunits, NR1 and NR2. In this study, we identified two NR1...

... structures, the formation of the cancellation signal requires activation of postsynaptic NMDA receptors on the principal neurons. We demonstrate here by immunohistochemistry that the somas and the initial portion of both apical and basal dendrites of the AENs are labeled with antibodies raised against...

..., an ammonia-sensitive fish. It suggests that the hearts of most, if not all, fish species are protected against ammonia. MK-801, an NMDA receptor blocker, was found to have a protective effect against ammonia intoxication in the oriental weatherloach,which suggests that the NMDA receptor, as in mammals...

...Robert J. Dunn; Daniele Bottai; Leonard Maler ABSTRACT The complete sequences and expression patterns of the NR1 (aptNR1) subunit of the N -methyl-D-aspartate (NMDA) receptor and its alternative splice isoforms have been determined for the weakly electric fish Apteronotus leptorhynchus...

...+ ] i while cerebral adenosine levels increase 12-fold. Employing cell-attached single-channel patch-clamp techniques, we studied the effect of adenosine (200 µmol l −1 ) and anoxia on NMDA receptor open probability ( P open ) and current amplitude. After 60 min of anoxic perfusion, channel P open...
