Distribution of the P2X2 receptor and chemical coding in ileal enteric neurons of obese male mice (ob/ob)

Figure 4 Neuronal density and number of neurons per ganglion. Neuronal density (neurons/cm²) (A), neurons per ganglion (B) immunoreactive for the P2X2 receptor, nitric oxide synthase (NOS), acetyltransferase (ChAT), and calretinin and positive for nicotinamide adenine dinucleotide-diaphorase (NADH) activity in the ileum myenteric plexus, and the densities of Dogiel Type I and II neurons immunoreactive for calretinin (C) in control and obese mice are shown. ^aP < 0.05 vs control, mean ± SE, Student’s t-test.
