Figure 6.

Confocal laser scanning microscopy (CLSM) images of synaptobrevin-2-LIR (VAMP-2) in taste buds of rat or mouse circumvallate papillae. Longitudinal sections show a large subset of taste cells and nerve processes displaying synaptobrevin-2-LIR in rat (A) and mouse taste buds (B). Transverse sections show synaptobrevin-2-LIR in rat (C-E) and mouse taste buds (F-H). The red are immunoreactive taste cells and nerve processes (C and F). Immunoreactivity is restricted to the cytoplasm (red) in both transverse and longitudinal sections. Sytox-stained nuclei (green) are shown in D and G and merges are shown in E and H. Scale bars = 20 μm.
