Co-localisation of somatostatin and GRP in axons with strong VGLUT2 immunoreactivity. a-c, Immunostaining with antibodies against GRP (green), somatostatin (Som, blue) and VGLUT2 (red) in a projection of 5 confocal sections (0.3 μm z-separation). d shows a merged image. Several profiles showing all three types of immunoreactivity are visible in this field, and 3 of these are indicated with arrows. Scale bar = 5 μm.
