| Abstract | Using specific radioimmunoassay and immunocytochemistry for neurokinin A (NKA) and neurokinin B (NKB), distribution and localization of the two peptides in human peripheral tissues were studied. Both NKA-like immunoreactivity (NKA-LI) and NKB-like immunoreactivity (NKB-LI) were present in the walls of the gut and gall bladder and in the pancreas. In the gut, the values for NKA-LI were 0.56-35.73 pmol/g wet weight, while those in pancreas and gall bladder were 0.64-0.68 and 0.36 pmol/g wet weight, respectively. The values of NKB-LI were 0.45-2.66 pmol/g wet weight in the gut, 0.93-1.65 pmol/g wet weight in the pancreas, and 0.30 pmol/g wet weight in the gall bladder. The immunocytochemical reactivity to both peptides was localized to ganglia of the submucosal and myenteric nerve plexuses in the gut wall, and to neurons in the muscle layer and mucosa of the gut wall. Weak but positive NKA-LI appeared in nerve cells of the pancreas, while NKB-LI was not detectable in the pancreas. Conversely, in the gall bladder wall, NKA-LI was undetectable while a very faint NKB-LI was found in the muscle layer. The localization of NKA corresponded closely to that of NKB in the tissues although the relative concentrations of the peptides varied from organ to organ. |
