Dolais-Kitabgi et al., Endocrinology 1979
:
Effect of
neurotensin on insulin,
glucagon , and somatostatin release from isolated pancreatic islets ... The
effects of
neurotensin on the release of insulin,
glucagon , and somatostatin were investigated in isolated pancreatic islets prepared from 3- to 4-day-old rats and maintained in culture for 48 h before use ... In 20-min incubations at 3 mM glucose,
neurotensin ( 10-100 nM )
increased the release of insulin,
glucagon , and somatostatin by 60 %, 90 %, and 110 %, respectively ... It is concluded that neurotensin exerts a dual effect on the endocrine pancreas in vitro : 1 ) at low glucose concentration and over short term ( 20 min ) incubations, the peptide stimulates insulin, glucagon, and somatostatin release ; and 2 ) under stimulated conditions ( high glucose or arginine ),
neurotensin inhibits insulin,
glucagon , and somatostatin release
Itatsu et al., Endocrinol Jpn 1981
:
The histaminergic mechanism of
neurotensin induced
glucagon release from isolated rat pancreatic islets ... Both histamine ( 100 microM ) and
neurotensin ( 100 nM )
stimulated glucagon release from the isolated islets, but not insulin release ... The stimulation of
glucagon release occurred in the
presence of 10 and 100 nM
neurotensin , while the release of insulin was inhibited in the presence of 1 and 10 nM neurotensin ... The
neurotensin induced
glucagon release was completely inhibited by 1 mM metiamide, an histamine H2-receptor antagonist, added to the incubation medium and not inhibited by 1 mM diphenhydramine, an histamine H1-receptor antagonist ... The results indicate that the histaminergic mechanism, including the H2-receptor system, may be involved in
neurotensin induced
glucagon release from the endocrine pancreas
Ukai et al., Endocrinology 1977
:
Effect of somatostatin on
neurotensin induced
glucagon release and hyperglycemia ... Infusion of somatostatin along with neurotensin suppressed
glucagon and insulin
responses to
neurotensin and prevented the rise in blood glucose levels
Dumoulin et al., Endocrinology 1998
:
Peptide YY,
glucagon-like peptide-1, and
neurotensin responses to luminal factors in the isolated vascularly perfused rat ileum
