Figure 4From: Characterization of sensory neuron subpopulations selectively expressing green fluorescent protein in phosphodiesterase 1C BAC transgenic mice GFP- Pde1c neurons in the superficial dorsal horn are not immunoreactive for NK1R or GABA. High magnification single confocal optical sections of lamina I and II to show immunoreactivity to GFP (A, D) and either NK1R (B) or GABA (E). Overlays are shown in (C) and (F). Arrows denote GFP-immunoreactive neurons that are not immunoreactive for the respective marker. Asterisks show NK1R- or GABA-immunoreactive neurons that are not immunoreactive for GFP. NK1R-immunoreactive neurons appear as red circular rim staining because immunostaining is mainly associated with the cell membrane. Scale bar in A, 10 μm applies to all panels.Back to article page
