Abstract

The binding site of gurmarin, a peptide inhibiting the sweet-taste sensation, was studied in taste buds in rat circumvallate papillae by means of a histochemical technique, Frozen sections of tongues were incubated with gurmarin conjugated with biotin and thereafter examined with a light microscope, Positive reactivity for the peptide was localized to the taste hairs, the apical projections of taste bud cells, The reaction appeared in about 10% of the circumvallate taste buds examined, As electrophysiological studies indicate that gurmarin suppresses the sweet-taste sensation at the level of reception, the present study suggests that the receptor for sweet taste is located on the taste hairs and, furthermore, is present only in a certain, limited number of the taste buds.
