Glucose Homeostasis: Pancreatic Islets and Insulin Secretion01:27

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 co-secreted in...

Insulin: Biosynthesis, Chemistry, and Preparation

The endoplasmic reticulum (ER) of pancreatic β-cells synthesizes preproinsulin, which consists of a signal peptide, A and B chains, and a C-peptide. Preproinsulin is then cleaved and folded into proinsulin, which translocates to the Golgi apparatus for sorting and packaging into secretory granules. In these granules, enzymatic clipping generates insulin and C-peptide.
Damage or functional impairment of β-cells inhibits insulin production, leading to diabetes. Diabetes treatment primarily uses...

Area of Science:

  • Endocrinology and Metabolism
  • Immunology
  • Regenerative Medicine

Context:

  • Type 1 diabetes (T1DM) is a prevalent metabolic disorder characterized by autoimmune destruction of pancreatic beta-cells.
  • Current treatments like insulin therapy and islet transplantation have limitations, including glycemic control issues, donor shortages, and immunosuppression.
  • Chronic hyperglycemia in T1DM leads to severe cardiovascular complications and reduced life expectancy.

Purpose:

  • To review novel strategies for generating functional beta-cells.
  • To explore the conversion of various pancreatic cell types into insulin-producing beta-cells.
  • To identify new research avenues for type 1 diabetes therapeutics.

Summary:

  • This review details innovative approaches for converting non-beta pancreatic cells (acinar, ductal, endocrine) into functional beta-cells.
  • These methods represent a promising alternative to conventional T1DM management strategies.
  • The focus is on generating endogenous insulin-producing cells to restore glycemic control.

Impact:

  • Potential to overcome limitations of current type 1 diabetes treatments.
  • Opens new research directions for beta-cell regeneration and T1DM cure.
  • Could significantly improve the quality of life and life expectancy for T1DM patients.
