Figure 3From: Heme oxygenase-1 plays a pro-life role in experimental brain stem death via nitric oxide synthase I/protein kinase G signaling at rostral ventrolateral medullaPreferential upregulation of HO-1 in RVLM neurons during the pro-life phase. Illustrative laser scanning confocal microscopic images showing cells in RVLM that were immunoreactive to NeuN (green fluorescence) and additionally stained positively for HO-1 or HO-2 isoform (red fluorescence) in sham controls (Basal) or during Phases I and II Mev intoxication. *Denotes location of nucleus in corresponding RVLM neuron. These results are typical of 4 animals from each experimental group. Scale bar, 10 μm.Back to article page
