Insulin: Biosynthesis, Chemistry, and Preparation01:25

Insulin: Biosynthesis, Chemistry, and Preparation

858
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...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

1.7K
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...

iPS Cell Differentiation

2.9K
The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Tissue Renewal without Stem Cells

2.0K
After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.
However, failure of such a system...

Area of Science:

  • * Regenerative medicine and immunology.
  • * Diabetes research and therapeutic strategies.

Background:

  • * Islet transplantation is a potential treatment for type 1 diabetes, but its success is limited compared to whole-pancreas transplantation.
  • * Mouse models are widely used in islet research, yet significant disparities exist between murine and human transplant outcomes.
  • * A shortage of transplant-grade islets necessitates a deeper understanding of factors influencing long-term islet survival and function.

Purpose of the Study:

  • * To review the current status of clinical islet transplantation.
  • * To identify similarities and differences between mouse and human islets relevant to transplantation.
  • * To explore interventions aimed at generating a larger pool of beta-cells for clinical use.

Main Methods:

  • * Comprehensive literature review of clinical islet transplantation outcomes.
  • * Comparative analysis of murine and human islet characteristics.
  • * Examination of emerging therapeutic strategies for beta-cell regeneration and enhancement.

Main Results:

  • * Clinical islet transplantation outcomes lag behind whole-pancreas transplantation.
  • * Significant biological and functional differences exist between mouse and human islets, impacting translational research.
  • * Various strategies are under investigation to improve beta-cell availability and transplant efficacy.

Conclusions:

  • * Bridging the gap between mouse models and human outcomes is critical for advancing islet transplantation.
  • * Further research into factors affecting islet survival and function is essential.
  • * Developing novel therapeutic targets and beta-cell sources is crucial for improving type 1 diabetes treatment.
