Figure 5From: Evidence for a role of glutamate as an efferent transmitter in taste budsVGLUT1 and 2 immunoreactivity in geniculate ganglion neurons. A-C: Laser scanning photomicrographs of VGLUT2 (red) and P2X2 (blue). D-F: VGLUT1 (green), VGLUT2 (red). Note that all P2X2-expressing neurons also express VGLUT2 and that VGLUT2 completely co-localizes with VGLUT1.Back to article page
