Involvement of alpha1 and beta-adrenoceptors in adrenaline stimulation of the glucagon-secreting mouse alpha-cell. | |||||||||||||||
| |||||||||||||||
|
The results indicate that alpha1- and beta-adrenoceptors on the alpha-cells mediate adrenaline-stimulated glucagon secretion. | |||||||||||||||
| |||||||||||||||
|
Stimulation of glucagon release and inhibition of insulin secretion from the islets of Langerhans are important for the blood-glucose-elevating effect of adrenaline. | |||||||||||||||
| |||||||||||||||
|
In the present study we investigated how adrenaline affects the cytoplasmic Ca2+ concentration, which controls glucagon secretion from the pancreatic alpha-cell. | |||||||||||||||
| |||||||||||||||
|
In controls, 2-DG stimulated insulin and glucagon secretion and induced hyperglycemia (P less than 0.01). | |||||||||||||||
| |||||||||||||||
|
Furthermore, capsaicin-sensitive sensory nerve fibers are partially involved in 2-DG-induced glucagon secretion and hyperglycemia, whereas sensory nerves are not involved in 2-DG-induced insulin secretion. | |||||||||||||||
| |||||||||||||||
|
Neonatal capsaicin-treatment in mice: effects on pancreatic peptidergic nerves and 2-deoxy-D-glucose-induced insulin and glucagon secretion. | |||||||||||||||
| |||||||||||||||
|
Patch-clamp recordings and glucagon release measurements were combined to determine the role of plasma membrane ATP-sensitive K+ channels (KATP channels) in the control of glucagon secretion from mouse pancreatic alpha-cells. | |||||||||||||||
| |||||||||||||||
|
We conclude that the KATP channel is involved in the control of glucagon secretion by regulating the membrane potential in the alpha-cell in a way reminiscent of that previously documented in insulin-releasing beta-cells. | |||||||||||||||
| |||||||||||||||
|
In mice lacking functional KATP channels (SUR1-/-), glucagon secretion in the absence of glucose was lower than that observed in wild-type islets and both glucose (0-20 mmol/l) and the sulfonylureas failed to inhibit glucagon secretion. | |||||||||||||||
| |||||||||||||||
|
The sulfonylureas tolbutamide (100 micromol/l) and glibenclamide (100 nmol/l) inhibited glucagon secretion to the same extent as a maximally inhibitory concentration of glucose. | |||||||||||||||
| |||||||||||||||
|
ATP-sensitive K+ channel-dependent regulation of glucagon release and electrical activity by glucose in wild-type and SUR1-/- mouse alpha-cells. | |||||||||||||||
| |||||||||||||||
|
Patch-clamp recordings and glucagon release measurements were combined to determine the role of plasma membrane ATP-sensitive K+ channels (KATP channels) in the control of glucagon secretion from mouse pancreatic alpha-cells. | |||||||||||||||
| |||||||||||||||
|
Whereas insulin secretion increased monotonically with increasing external K+ concentrations (threshold 25 mmol/l), glucagon secretion was paradoxically suppressed at intermediate concentrations (5.6-15 mmol/l), and stimulation was first detectable at >25 mmol/l K+. | |||||||||||||||
| |||||||||||||||
|
In wild-type mouse islets, glucose produced a concentration-dependent (half-maximal inhibitory concentration [IC50]=2.5 mmol/l) reduction of glucagon release. | |||||||||||||||
| |||||||||||||||
|
In mice lacking functional KATP channels (SUR1-/-), glucagon secretion in the absence of glucose was lower than that observed in wild-type islets and both glucose (0-20 mmol/l) and the sulfonylureas failed to inhibit glucagon secretion. | |||||||||||||||
| |||||||||||||||
|
-Cell Specific Overexpression of Human Islet Amyloid Polypeptide
Exogenous administration of islet amyloid polypeptide (IAPP) has been shown to inhibit both insulin and glucagon secretion. | |||||||||||||||
| |||||||||||||||
|
in view of the inhibitory influence of insulin on glucagon secretion. | |||||||||||||||
| |||||||||||||||
|
administration of IAPP at supraphysiological doses inhibits glucagon secretion [811]. | |||||||||||||||
| |||||||||||||||
|
glucagon secretion [811]. | |||||||||||||||
