Abstract
The present invention relates to modulation of the perception of either taste or smell through modulation of the activity of GRKs which regulate the desensitization process of the taste and smell receptors. By the process of either inhibiting or enhancing GRK activity at the receptor site a modulation in perception of taste and smell can be achieved. The invention discloses methods of treatment as well as methods of discovering compounds useful in the invention. The invention further discloses methods of treating eating disorders or obesity using compositions of the type disclosed in the invention.

- 5. A formulation for modulating the perception of taste or smell comprising a composition which inhibits the activity of GRK formulated for administration directly to the taste receptors on the tongue or the smell receptors in the nose.
- 9. A food or an odorant to which has been added a GRK modulator sufficient to modulate a subject'"'"'s perception of a taste or smell of the food or odorant when consumed.
- 14. A method of reducing the amount of food consumed in a subject comprising administering a GRK modulator which enhances unpleasant taste or smell.
-
17. A method of screening for compounds capable of modulating taste or smell comprising:
-
a) selecting a composition which inhibits the activity of GRK; b) administering the composition to a test subject such that GRK in the vicinity of the taste or smell receptors is inhibited; c) determining if the administration of the composition modulates the subject'"'"'s perception of smell or taste; and d) selecting compounds which exhibit modulation of smell or taste. - View Dependent Claims (18, 19, 20)
