Amyloid Fibrils

13.2K
Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Insulin: Biosynthesis, Chemistry, and Preparation

2.2K
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...

Type I Diabetes II: Pathophysiology

1
Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular...

Type I Diabetes I: Introduction

1
Type 1 diabetes mellitus is a chronic metabolic disorder characterized by an absolute deficiency of insulin resulting from the autoimmune destruction of pancreatic β-cells. Although it can occur at any age, it is most commonly diagnosed in childhood, adolescence, or early adulthood. The loss of insulin production impairs cellular glucose uptake, resulting in persistent hyperglycemia and necessitating lifelong insulin therapy.Autoimmune Destruction of β-CellsThe hallmark of type 1...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

3.2K
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...

Summary
This summary is machine-generated.

Insulin-derived amyloidosis, a complication of insulin therapy, can impair insulin absorption, leading to poor glycemic control. Early recognition and histopathological assessment are crucial for managing these localized reactions.

  • Endocrinology
  • Pathology

Background:

  • Amyloidosis involves extracellular deposition of protein fibrils in organs.
  • Insulin-derived amyloidosis is a rare but significant complication of insulin therapy.
  • Localized amyloid deposits at insulin injection sites can impede insulin absorption.

Purpose of the Study:

  • To review the clinical significance of insulin-derived amyloidosis.
  • To highlight diagnostic criteria and management strategies for insulin injection site amyloidosis.

Main Methods:

  • Literature search of PubMed using the term "insulin amyloidosis".
  • Review of full-text English articles and relevant cross-references.
  • Data collection and synthesis of findings related to insulin-derived amyloidosis.

Main Results:

  • Insulin injection site amyloidosis can lead to suboptimal glycemic control and increased insulin requirements.
  • Symptoms include firm or hard local reactions that persist despite cessation of injections.
  • Management involves changing injection sites and/or surgical excision of the amyloid mass.

Conclusions:

  • Insulin-derived amyloidosis is an important consideration in patients with persistent local reactions at insulin injection sites.
  • Histopathology and immunohistochemistry are essential for diagnosis.
  • Prompt recognition and appropriate management can improve glycemic control.
