In conclusion, 1) high levels of gene expression and secretion of NPY are found in a rat insulinoma cell line (INS-1). 2) Accumulation of cAMP induced by forskolin or a gluco-incretin (GLP-1) induces a further increase in NPY gene expression and release. 3) NPY secretion is not modulated by low or high glucose concentrations in the medium. 4) Induction of NPY, a known inhibitor of insulin secretion, may represent a novel counterregulatory mechanism of insulin secretion, limiting the stimulatory effect of GLP-1 on insulin secretion.

Based on experiments in the pithed guinea-pig, it is suggested that prejunctional facilitatory beta-adrenoceptors may also be involved in the regulation of the NPY release, since infusion of isoprenaline elicited a facilitation of the PNS-induced increase of plasma NPY-LI levels which could be antagonised by propranolol.
