GFP and sst 2A expression among different neurochemical interneuron populations in the PrP-GFP mouse. a-e, a field from lamina II contains three GFP-labelled neurons, all of which are sst2A+. The cells numbered 1 and 3 show weak immunoreactivity for both nNOS and galanin, while the cell numbered 2 is strongly nNOS+ and galanin-. f-j, a nearby region from the same section includes a cell with weak GFP (arrow) that is sst2A+ and shows strong galanin immunoreactivity, but lacks nNOS. k-o, This field from lamina II includes a GFP cell (arrow) that is sst2A+ but does not contain NPY or parvalbumin (PV). Two nearby cells are indicated with arrowheads. The one on the left is PV+/NPY-, while the one on the right is PV-/NPY+. Both of these cells lack sst2A. Scale bar (in o): 20 μm.
