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

Figure 2 Immunoreactivity for P2X₂ receptor (A, C, E, G) and calretinin (B, D, F, H) was examined in the ileum myenteric neurons of the control group (A, B, E, F) and the obese group (C, D, G, H). Single arrows show double labeling for P2X₂ receptor and calretinin (CalR) in the neurons of the control group (CG) (A, B) and the obese group (OG) (C, D). E, F: An example of a Dogiel type I neuron with many lamellar and short dendrites; G, H: A neuron with Dogiel type II morphology with a round and smooth cell body and lipofuscin evident in the cytoplasm (arrow).
