Synaptophysin and synaptoporin are two homologous integral membrane proteins of small synaptic vesicles. Here, the distribution of the corresponding transcripts in the CNS of the rat was investigated by in situ hybridization using sequence-specific oligonucleotide probes. Synaptophysin mRNA was abundantly distributed through all major brain regions, whereas(More)
The expression of five genes (GluR A; B; C; D; GluR 5) encoding functional subunits of glutamate receptors was investigated in the rat retina using in situ hybridization with oligonucleotide probes. All five genes are expressed in the retina. All probes label cell bodies in the ganglion cell layer as well as somata in the inner third of the inner nuclear(More)
Gamma-aminobutyric acid (GABA) and the GABAergic system play an important role in the efferent modulation of cochlear function. We examined surface preparations of guinea pig and mouse cochleae by in situ hybridization using radioactive labelled oligonucleotides for several subunits of the GABAA receptor. Frozen sections of rat and guinea pig brain (cortex,(More)
The inhibitory neurotransmitter gamma-aminobutyric acid (GABA) is most likely involved in the efferent cochlear neurotransmission. In situ hybridization (ISH) results in specific annealing of a labelled nucleic acid probe to complementary sequences in fixed tissue and allows subsequent visualization of the location of the probe. We used the ISH technique to(More)
