Research Summary

Dr. Margolskee’s long-standing research focus is on the molecular mechanisms of taste transduction, utilizing molecular biology, biochemistry, transcriptomics, structural biology, electrophysiology and transgenesis to study the mechanisms of signal transduction in mammalian taste cells. More recently he has been studying the chemosensory functions of taste signaling proteins in gut endocrine cells and gingival innate immune cells. Other projects in the Margolskee lab focus on taste stem cells and endocrine/metabolic properties of taste cells.
