Effects of protein deprivation and re-feeding on P2X2 receptors in enteric neurons

Figure 3 The density (neuron/cm²) of neurons immunoreactive for the P2X₂ receptor, nitric oxide synthase, calbindin, calretinin, and choline acetyltransferase in the ileal myenteric plexus in the N, D and DR groups. ^aP < 0.02, ^bP < 0.01, ^cP < 0.002, ^dP < 0.001 vs N and DR groups. NOS: Nitric oxide synthase; ChAT: Choline acetyltransferase.
