Summary
The extracellular matrix (ECM) and its integrin receptors play a role in insulin resistance. Understanding ECM remodeling in metabolic tissues may lead to new treatments for type 2 diabetes (T2D).
Area of Science:
- Biochemistry
- Cell Biology
- Metabolic Research
Background:
- The extracellular matrix (ECM) is a dynamic tissue component undergoing remodeling during injury and repair.
- Growing evidence links ECM remodeling to diet-induced insulin resistance in humans and rodents.
- Integrin receptors, which bind the ECM, are involved in regulating insulin action.
Purpose of the Study:
- To review the current understanding of the ECM, integrins, and insulin action.
- To explore these interactions within key metabolic tissues: muscle, liver, and adipose tissue.
Main Methods:
- Literature review of existing research on ECM, integrins, and insulin signaling.
- Synthesis of findings from human and rodent studies.
- Focus on muscle, liver, and adipose tissue.
Main Results:
- ECM remodeling is increasingly recognized as a factor in insulin resistance.
- Integrin signaling pathways are implicated in the modulation of insulin sensitivity.
- Specific roles of ECM and integrins vary across different metabolic tissues.
Conclusions:
- ECM remodeling and integrin signaling are critical regulators of insulin action.
- Further research into these mechanisms could reveal novel therapeutic targets.
- Potential for new treatments for insulin resistance and type 2 diabetes (T2D).

6.7K
Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. This extracellular matrix (ECM) is composed of fibrous proteins like collagen, elastin, and fibronectin in a ground substance consisting of interstitial fluid, cell adhesion proteins, and proteoglycans. The proteoglycans form a gel-like material in the spaces between cells and provide hydration, buffering, binding, and force...

01:28Insulin: The Receptor and Signaling Pathways
6.2K
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...

Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.

01:24Overview of Cell-Matrix Interactions
9.9K
The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...

3.8K
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.
