Figure 4. ATP responses in TRPM5-GFP+ cells.

Figure 4

A. A TRPM5-GFP+ cell responds with increased intracellular Ca2+ to 10 μM ACh and 10 μM ATP. B. A TRPM5-GFP+ cell responsive to 15 mM denatonium also responds to 10 μM ATP but not to 500 μM (an irritatingly high concentration) lilial. The adjacent cell (GFP-, gray trace) only responded to ATP. The PLC inhibitor U73122 (2 μM) blocked the denatonium response in the GFP+ cell completely but did not block the ATP responses in either cell.
