P2X2 receptors and P2Y4 receptors are ATP-activated cell surface receptors that gate movement of K+, Na+, and Ca2+. We used immunocytochemistry for P2X2 and P2Y4 receptors as well as taste cell type markers to learn if P2X2 immunoreactivity (IR) is present in nerve processes in close apposition to Type II and/or Type III taste cells. We also tested to see if P2Y4 IR is present in Type II and/or Type III taste cells. Our results indicate that P2X2 is present only in intragemmal nerve processes. P2X2-LIR nerve processes form close contacts with Type II and Type III taste cells. P2Y4 …
