NOTE ADDED IN PROOF
Holland et al. (Holland VF, Zampighi GA, and Simon SA, Tight junctions in taste buds: possible role in perception of intravascular gustatory stimuli, Chem Senses 16: 69–79, 1991) reported that ions and certain small molecules penetrated into taste buds in canine lingual epithelium. This could indicate there are species differences in the barrier. Moreover, as we had speculated in our report, Holland et al. (ibid) also suggested that intravascular taste might arise from chemical stimuli reaching receptors located on the apical, chemosensory tips of taste cells.
