| | Chemical & Engineering News: Latest News - Sour Revealed |
 | | SOUR SIGNS A red fluorescent label that binds specifically to a newly found sour receptor distinguishes sour-sensing cells in taste buds (on a grey background of tongue tissue) from sweet-, bitter-, and umami-sensing cells, which are all marked with green fluorescent tags. |
 | | In a sleuthing exercise summoning bioinformatics, genetic studies, and behavioral tests with mice, a research team led by Zuker and Nicholas J. Ryba of the National Institute of Dental and Craniofacial Research, Bethesda, Md., found what they were looking for (Nature 2006, 442, 934). |
 | | The researchers found that only one of these DNA sequences, corresponding to the ion-channel protein PKD2L1, is expressed in a subset of taste bud cells separate from those dedicated to sweet, bitter, or umami tastes. |
