Insulin: The Receptor and Signaling Pathways01:28

Insulin: The Receptor and Signaling Pathways

2.4K
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...

Glucagon-like Receptor Agonists01:24

Glucagon-like Receptor Agonists

762
Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

Cell Specific Gene Expression01:58

Cell Specific Gene Expression

16.1K
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

Regulation of Food Intake01:30

Regulation of Food Intake

2.2K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

11.6K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

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...

Area of Science:

  • Endocrinology
  • Metabolic Disorders
  • Adipose Tissue Biology

Background:

  • Leptin, a hormone from adipose tissue, regulates energy homeostasis via leptin receptors (LepR), primarily in the hypothalamus.
  • Leptin's known effects include reducing appetite by influencing hypothalamic neuropeptides.
  • Emerging evidence highlights leptin's role in stimulating thermogenesis in brown adipose tissue (BAT) and white adipose tissue (WAT) browning.

Purpose of the Study:

  • To review the therapeutic potential of leptin for obesity and metabolic disorders.
  • To explore leptin's dual action: satiating effects and thermogenic properties.

Main Methods:

  • Literature review of studies on leptin's role in energy homeostasis.
  • Analysis of research on leptin's effects on brown adipose tissue (BAT) and white adipose tissue (WAT).
  • Examination of therapeutic strategies targeting leptin and thermogenesis.

Main Results:

  • Leptin influences energy balance through hypothalamic pathways and direct thermogenic effects.
  • Activation of BAT and WAT browning by leptin contributes to metabolic improvements.
  • Studies, primarily in rodent models, show potential for BAT activation to treat metabolic disorders.

Conclusions:

  • Leptin offers therapeutic potential for obesity and metabolic dysfunction beyond appetite suppression.
  • Leveraging leptin's thermogenic capabilities presents a promising strategy for metabolic health.
  • Further research into leptin's multifaceted roles could lead to novel obesity treatments.
