Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

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...

Insulin Secretory Vesicles

Insulin Secretory Vesicles

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...

Background:

Primary cilia are crucial signaling organelles found on pancreatic islet cells.
Their function is vital for regulating islet endocrine function.
Dysregulation of primary cilia contributes to diabetes development.

Purpose of the Study:

To review experimental models for studying islet primary cilia.
To summarize current knowledge on cilia's role in regulating islet hormone secretion.
To explore the implications of cilia dysfunction in pancreatic diseases.

Main Methods:

Review of genetic deletion models targeting cilia components.
Analysis of studies investigating cilia-mediated signaling in islets.
Synthesis of research on endocrine and exocrine pancreatic functions.

Main Results:

Primary cilia are present on all major islet endocrine cell types.
Perturbation of pancreatic cilia leads to both endocrine and exocrine defects.
Cilia dysfunction is implicated in human diseases.

Conclusions:

Primary cilia are key regulators of pancreatic islet function.
Further research is needed on cilia's role in paracrine/juxtacrine signaling, GPCR pathways, and endocrine-exocrine crosstalk.
Understanding islet cilia mechanisms is critical for diabetes and pancreatic disease research.
