Other studies will explore how odour molecules modify
taste cell responses and, ultimately, human taste perception.
Using pharmacological approaches, the researchers identified the so-called signaling proteins within the immature
taste cells that cause the developing cells to multiply and turn into specific cell types.
Unexpectedly, this sensitivity to intracellular acidification is attributed to relatively ubiquitous ion channels, [K.sub.2]P, whose distribution is not restricted to sour
taste cells, being expressed in a wide variety of tissues and organs: brain, sperm, heart, kidney, liver, vascular smooth muscle cells, skeletal muscle, and so on (see Table 1) [25, 54, 185].
But finding
taste cells on land animals wasn't easy.
Change in taste preference related to ageing of
taste cells in rat.Experientia.
Non-tasters are simply those people with a very low number of
taste cells and who essentially perceive the world, at least from a taste perspective, as dulled.
Further, selective stimulation of the
taste cells expressing T2Rs is sufficient to elicit a strong aversive response in mice (Mueller et al., 2005).
An American biotechnology company has discovered ``bitter blockers'' which stop production of a protein released by
taste cells.
"Each taste bud is an onion-shaped cluster of 50 to 100
taste cells," says scientist Julie Mennella at Philadelphia's Monell Taste Laboratory.
When these chemicals mix with the saliva in your mouth, they trigger the
taste cells. The
taste cells then send information about the chemicals along the nerves to your brain, and your brain tells you what you are tasting.
He found that fatty acids -- an important component of fats -- produce a noticeable response in the
taste cells of laboratory rats.
Gustatory or
taste cells react to food and beverages.
