Research Summary

The theme of my laboratory lies in defining the chemically mediated changes in taste cell transduction. Current projects of the laboratory include 1) cloning and characterization of ion channels from human and rodent taste tissue that are involved in sour and salty taste; 2) reconstitution of taste cell ion channels in lipid bilayers; 3) characterizing gene expression in individual taste cells; 4) defining the roles of inflammatory agents and neuromodulators in taste cells; 5) producing taste related proteins through tissue culture to study structure and function.
