Tug-of-war receptors for sour taste in fruit flies sheds light on human taste biology

(Monell Chemical Senses Center) His team, including authors Tingwei Mi, John Mack, and Christopher Lee from the Monell Center and University of Pennsylvania, found that flies use two distinct types of gustatory (taste) receptor neurons (GRNs), which are analogous to taste receptor cells in mammals, to discriminate slightly from highly sour foods. One group of GRNs are maximally activated by low acidity, while the other group displayed its best responses to high acidity.
