Mouse taste receptor cells survive from 3-24 days, necessitating their regeneration throughout adulthood. In anterior tongue, sonic hedgehog (SHH), released by a subpopulation of basal taste cells, regulates transcription factors Gli2 and Gli3 in stem cells to control taste cell regeneration. Using single-cell RNA-Seq we found that Gli3 is highly expressed in Tas1r3-expressing taste receptor ce...

Taste buds are assemblies of elongated epithelial cells, which are innervated by gustatory nerves that transmit taste information to the brain stem. Taste cells are continuously renewed throughout life via proliferation of epithelial progenitors, but the molecular regulation of this process remains unknown. During embryogenesis, sonic hedgehog (SHH) negatively regulates taste bud patterning, su...

There is increasing interest in developing robots that can sense and respond to plumes of volatile chemicals released into the atmosphere. However, chemicals with a molecular weight greater than 300 have very low volatility and do not produce detectable plumes. Such chemicals can be detected by taste and this paper describes a robot called TASTI that is equipped with a sensor for detecting chem...

This paper presents a cooking technique by a microwave-excited plasmoid ("fireball") in air atmosphere. The stable plasmoid is generated by localized microwaves from a solid or liquid substrate (e.g. salty water). Preliminary experiments yield relatively rapid cooking of meet chunks within such plasmoids. Their flavour and taste could be affected to some extent by the origin substrate content. ...

BACKGROUND AND AIM: The sense of taste is a chemical sense which allows everyone to perceive the flavor of what is eaten or drunk. Also, the sense of olfaction is also a chemical sense contributing to the sense of taste to perceive the taste and flavor of food. In the present work, the gustatory and olfactory function in pre- and postmenopausal women and men were studied and compared to each ot...

Effects of subjects' taste sensitivity (expressed as taste detection threshold), tastant quality and taste transduction mechanism on pulsation-induced taste enhancement were tested. Taste intensities of pulsatile MSG and NaCl stimuli at pulsation periods below, at and above individual taste fusion periods (TFP in seconds) were compared to taste intensities of a continuous reference of the same ...

Multidimensional food perception is based mainly on gustatory and olfactory function. Recent research has demonstrated that hypobaric pressure impairs gustatory function and that background noise or distracting auditory stimulation impairs olfactory function. Using a hypobaric chamber, the odor identification, discrimination, and thresholds as well as taste identification and threshold scores w...

Taste buds contain three types of taste cells. Each type can respond to taste stimulation, and type II and III taste cells are electrically excitable. However, there are differences between the properties of type II and III taste cells. In this study, we found that Fxyd6, an Na,K-ATPase regulator gene, is expressed in type II taste cells in the taste buds of mice. Double-labeled in situ hybridi...
