NPY and VGF co-localizes in some neuronal structures in the human NTS of control and diabetic subjects.

<p>Confocal image of the NTS at level III: NPY and VGF are visualized in green-Cy2 and red-Cy3, respectively. The white arrows indicate yellow co-localizing cellular elements. Note that diabetic NTS shows the decrease in both NPY and VGF staining already observed with DAB-peroxyde staining e.g. in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0040070#pone-0040070-g002" target="_blank">figure 2</a>. Scale bar = 50 µm.
