title: VIP- and PACAP-induced salivary chromogranin A secretion in the isolated perfused submandibular gland of rats.
abstract: In the study reported in this paper, sensitive ELISA for rat CgA was developed using synthetic rat CgA(359-389) as antigen, N alpha-biotinylated glycylglycyl rat CgA(359-389), and antirat CgA(359-389) serum for the measurement of CgA-LI in rat saliva. CgA-LI in rat submandibular tissues and saliva was characterized by both immunohistochemical and immunochemical methods. Using isolated perfused rat submandibular gland. VIP at 0.1-1.0 nM in the presence of 0.1 microM ACh was found to cause CgA-LI secretion, whereas neither PACAP-27 nor PACAP-38 showed any effect on CgA secretion.
