Color photomicrographs showing colocalization of trkA with choline acetyltransferase (ChAT), p75 nerve growth factor receptor (NGFR), and serotonin. A–D: Colocalization of the high-affinity trkA (smooth brown product) and ChAT (granular blue-black) reaction product within striatal (A), nucleus basalis (B), and vertical limb of the diagonal band neurons (C,D). The arrow in C points to a single-labeled ChAT-ir neuron. E: Colocalization of high-affinity trkA (brown) and low-affinity p75 NGFR (granular blue-black) reaction product within the nucleus basalis. Arrow indicates a p75 NGFR-immunoreactive blood vessel. F: High-power photomicrograph illustrating a double-labeled basal forebrain neuron for both trkA and p75 NGFR. G: Colocalization of serotonin (brown) and trkA immunoreactivity (granular blue black) in the raphe magnus. Arrows indicate neurons single labeled for serotonin. H: High-power photomicrograph of a single serotonin (brown reaction product; arrow) and double-labeled neuron (serotonin brown and trk A granular blue-black staining) within the median raphe. Scale bars = 15 μm in A,D; 30 μm in B,C,E; 20 μm in F–G.
