Expression of the P2X2 receptor in different classes of ileum myenteric neurons in the female obese ob/ob mouse

Figure 3 Neuronal density (neurons/cm²) (A), the estimated total neuron number (B) and neurons per ganglion immunoreactive for P2X₂ receptor, nitric oxide synthase, choline acetyltransferase, calretinin, and positive for nicotinamide adenine dinucleotide-diaphorase activity in the ileum myenteric plexus of control and obese mice (C), and densities of Dogiel type I and II neurons immunoreactive for calretinin (D) in control and obese mice. ^aP < 0.05 vs control, mean ± SE, Student’s t-test. NOS: Nitric oxide synthase; ChAT: Choline acetyltransferase; NADH: Nicotinamide adenine dinucleotide.
