Intra-PVN injection of SB-222200 decreases c-Fos expression in magnocellular VP neurons in the PVN following HDZ injection. Left: VP immunoreactivity (red). Middle: c-Fos immunoreactivity (transmitted light). Right: composite images of the VP and c-Fos panels. A–F: images from a rat treated with an intra-PVN injection of 0.15 M NaCl and an intravenous injection of HDZ, whereas panels G–L are from a rat treated with an intra-PVN injection of SB-222200 and an intravenous injection of HDZ. C: higher magnification of VP neurons, one of which expresses c-Fos. H: asterisk indicates decrease in c-Fos expression in response to HDZ due to intra-PVN injection of SB-222200. Images correspond to plate 25 in Paxinos and Watson Rat Brain Atlas (45a). Scale bars are 50 μm.
