text: Taste-metabotropic glutamate receptor 4 (taste-mGluR4) and the heteromers
of T1R1 and T1R3 are candidate receptors involved in the sense of umami (monosodium
glutamate) taste. Although the expression of group III mGluRs (taste-mGluR4) has
been demonstrated in taste tissues, no mention has been made of the expression
of group I mGluRs (mGluR1 and mGluR5) in taste tissues. We examined the expression
of mGluR1 and mGluR5 in rat gustatory tissues by using reverse transcription-polymerase
chain reaction (RT-PCR), in situ hybridization, immunohistochemistry and immunoelectron
microscopy. RT-PCR assay showed that mGluR1α and mGluR1β mRNAs were expressed
in circumvallate papillae, but mGluR5 mRNA was not expressed. The positive signals
of mGluR1 mRNA were detected only in circumvallate taste buds by in situ hybridization
analysis. In cryosections of fungiform, foliate and circumvallate papillae, the
antibody against mGluRla gave intense labeling on the taste hairs in all taste
pores examined. In the developing taste buds, the positive signals of mGluR1α
in taste hairs gradually increased with the increase in number of taste bud cells.
These results show that, in addition to taste-mGluR4 and the heteromer of T1R1
and T1R3, mGluR1α may function as a receptor for glutamate (umami) taste sensation.
