Enteric cells in porcine duodenal inner submucosal plexuses in physiological conditions (C) and after indomethacin administration (I). Neurons containing the protein gene-product 9.5 (PGP 9.5) pan-neuronal marker (green) and other neuronal substances studied such as VIP (A, B), nNOS (C, D), SP (E, F), GAL (G, H), PACAP (I, J) and CART (K, L) colocalized with PGP 9.5 (yellow/orange). The arrows in the photos show co‐expression of PGP 9.5 and other test neurotransmitters.
