  • Title: The vasoactive intestinal peptide receptor-effector system is developmentally regulated in rat jejuno-ileal epithelial cells.
    Author: Fernandez-Moreno MD, Diaz-Juarez JL, Fernandez-Gonzalez MA, Sanchez-Franco F, Prieto JC.
    Journal: Biochem Int; 1988 Feb; 16(2):331-7. PubMed ID: 2835052.
    Abstract:
    The specific binding of vasoactive intestinal peptide (VIP) to its specific receptors as well as the stimulatory effect of the neuropeptide on cyclic AMP accumulation were studied in jejuno-ileal epithelial cells from 14-, 20- and 60-day-old rats. The potency and specificity of the VIP receptor-effector system did not vary during development. However, the concentration of VIP receptors and the efficiency of VIP stimulation of cyclic AMP generation increased from suckling to adult conditions, and VIP levels in jejuno-ileal tissue followed a parallel course.
