The release of glucagon induced in isolated rat islets by arginine or by calcium deprivation has been subjected to combined functional and morphological quantifications. Arginine-stimulated glucagon release was associated with a significant increase of morphological events linked to exocytosis. By contrast, the paradoxical events linked to exocytosis. By contrast, the paradoxical release of glucagon provoked by calcium deprivation, although accompanied by a significant loss of granule stores, was not associated with an increase of morphologically detectable exocytosis.
