Insulin Secretory Vesicles01:05

Insulin Secretory Vesicles

6.3K
Insulin secretory vesicles release insulin to stimulate blood glucose uptake and regulate carbohydrate metabolism. When the blood glucose levels increase, glucose enters the pancreatic β-islet cells through glucose transporters. Once inside, glucose is metabolized through glycolysis, the citric acid cycle, and the electron transport chain, producing ATP. This increase in ATP concentration closes ATP-sensitive potassium channels, leading to depolarization of the membrane and the opening of...

Insulin: The Receptor and Signaling Pathways01:28

Insulin: The Receptor and Signaling Pathways

6.0K
Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but...

Glucose Absorption Into the Small Intestine01:26

Glucose Absorption Into the Small Intestine

34.0K
Complex carbohydrates consumed cannot be absorbed into the small intestine in their original form. First, they must be hydrolyzed to a monosaccharide form such as glucose or galactose. These monosaccharides are then transported across the intestinal membrane and into the blood via transcellular transport. The intestinal epithelial cells allow the movement of these monosaccharides with a defined 'entry' through membrane transporter proteins present on their apical membrane and...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

2.8K
The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are...

  • Computational modeling

Background:

  • Glucose transport is crucial for human metabolism, regulated by insulin.
  • Insulin signaling controls glucose uptake via GLUT4 translocation.
  • Disruptions lead to metabolic disorders like type II diabetes.

Purpose of the Study:

  • To introduce a novel simulation tool for intracellular insulin response.
  • To incorporate recent findings on As160 and GEF interactions.
  • To offer a more accurate computational approach than traditional methods.

Main Methods:

  • Developed a simulation tool using statistical variations of kinetic constants and initial concentrations.
  • This approach mimics the complex intracellular environment more realistically.
  • Validated the tool by recapitulating in vitro insulin responses and Wortmannin inhibition.

Main Results:

  • The simulation successfully replicated observed in vitro insulin signaling dynamics.
