Nociceptin effect on intestinal motility depends on opioid-receptor like-1 receptors and nitric oxide synthase co-localization

Figure 3 Double-labeling of myenteric plexus whole-mount preparations (A-F; J-L) and cryosections (G-I) of mouse ileum (A-F) and mouse colon (G-L) demonstrating co-labeling in myenteric neurons of opioid-receptor like-1 immunoreactivity with the neuron-endocrine marker protein gene product 9. 5 or nitric oxide synthase. ORL1: Opioid-receptor like-1; NOS: Nitric oxide synthase; PGP: Protein gene product.
