The human sense of taste is crucial for the assessment of the chemical composition of food, a major determinant of food choice and thus, is critical for a healthy nutrition. A plethora of sour, salty, sweet, umami and bitter compounds have to be accurately and simultaneously detected by dozens of specialized taste receptors in the oral cavity as well as in non-gustatory tissues to trigger appropriate taste behaviors and other physiological responses, creating an enormous level of complexity. To match tastants with taste receptors and with their gustatory and non-gustatory effects, we use cell biological, biochemical and molecular methods, which are also suitable to identify taste modulators, to characterize receptor binding pockets and to study tastant mixture effects. Our research has resulted in the deorphanization of numerous bitter taste receptors, the discovery of the first selective bitter taste receptor blockers, and allowed a detailed insight into the architectures of ligand binding pockets of broadly tuned bitter taste receptors. Our data on receptor-tastant profiles will promote the prediction of taste characteristics of complex food and the repurposing of tastants for health improvements.

 

  • Understanding the molecular basis of human taste perception
  • Structure-function analyses of taste receptors – can we predict taste modifiers de novo?
  • Physiological functions of extra-oral taste receptors – are tastants drugs?
  • Evolution of taste receptors – how did nutritional habits evolve?
  • Discovery of taste modifiers and mixture effects – how are complex food items perceived?
