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

Figure 1 Co-localization of P2X₂ receptor immunoreactivity with nitric oxide synthase, calbindin, calretinin and choline acetyltransferase immunoreactivity in the ileal myenteric plexus in the N, D and DR groups. A-C: P2X₂ receptor-IR (green) co-localized with nitric oxide synthase (NOS)-IR (red); D-F: P2X₂ receptor-IR (green) co-localized with calbindin-IR (red); G-I: P2X₂ receptors (green) co-localized with calretinin (red); J-L: P2X₂ receptors (green) co-localized with choline acetyltransferase (ChAT) (red). Double-labeled neurons are indicated by arrows.
