Abstract

There is some evidence that the mammalian rod bipolar cell expresses ionotropic glutamate receptors. This is surprising in light of the strong evidence that the glutamate released by the rod photoreceptor acts upon a metabotropic glutamate receptor-mGluRo-present in the dendrites of the rod bipolar cell. To reexamine the issue of which glutamate receptor subunits may be present on the rod bipolar cell, an immunohistochemical study of acutely dissociated retinal cells was undertaken. Two monoclonal antibodies provided some evidence that GluR2 and/or GluR4, as well as NMDAR1 subunit, are present on the rod bipolar cell. A monoclonal antibody directed against the N-terminus of GluR2 labeled the rod bipolar cells, but two antisera directed against the C-terminus of the same subunit did not. One possible explanation for this discrepancy could be that the rare splice variant GluR2-long, which is endowed with a different C-terminus, could be expressed by the rod bipolar cell. To explore this possibility, RT-PCR was used to amplify the transcripts encoding GluR2 in the neural retina. This revealed that GluR2-long transcripts, with the flop exon, are present.
