Figure 3.

Coincidence between SNAP25 immunoreactivity and PKD2L1-YFP fluorescence is greater in posterior taste fields than in anterior taste fields. Confocal z-stack images of (A) fungiform, (B) soft palate, (C) circumvallate, and (D) foliate taste buds in transgenic PKD2L1-YFP mice. PKD2L1-YFP fluorescence is shown in green, SNAP25 immunoreactivity is shown in red, and P2X3 immunoreactivity is shown in blue to exclude SNAP25-positive nerve fibers from the cell count. All scale bars = 20 µm. (E) Venn diagrams show high coincidence of fluorescent PKD2L1 and SNAP25 marker in posterior taste fields and a lower coincidence in anterior taste fields. Chi-square test revealed a significant difference between the distributions of anterior and posterior taste fields, P < 0.0001.
