Insights

Hypertension alters the extracellular matrix (ECM) in the heart and blood vessels, leading to organ damage. This review examines how mediators affect ECM structure in hypertension.

Area of Science:

  • Cardiovascular Biology
  • Connective Tissue Research
  • Hypertension Pathophysiology

Background:

  • The extracellular matrix (ECM), rich in collagen, is crucial for connective tissue integrity.
  • Hypertension is increasingly linked to alterations in cardiac and vascular ECM composition.
  • These matrix changes contribute to clinical manifestations like left ventricular hypertrophy and reduced arterial compliance.

Purpose of the Study:

  • To review the mediators influencing extracellular matrix structure in hypertension.
  • To synthesize findings from both animal and human studies on this topic.

Main Methods:

  • Literature review of studies investigating ECM changes in hypertension.
  • Analysis of mediators impacting ECM composition.
  • Inclusion of data from animal models and human subjects.

Main Results:

  • Hypertension significantly impacts the cardiac and vascular extracellular matrix.
  • Matrix metalloproteinases and their inhibitors play a key regulatory role in ECM remodeling during hypertension.
  • Alterations in ECM contribute to end-organ ischemia via effects on cardiac and vascular structure.

Conclusions:

  • Mediators influencing ECM structure are critical in the pathophysiology of hypertension.
  • Understanding these mediators is essential for developing therapeutic strategies targeting hypertension-induced organ damage.

Extracellular Matrix01:26

Extracellular Matrix

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...

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.

Cell-matrix's Response to Mechanical Forces

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.

Overview of Cell-Matrix Interactions01:24

Overview of Cell-Matrix Interactions

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...
Role of Matrix Metalloproteases in Degradation of ECM01:23

Role of Matrix Metalloproteases in Degradation of ECM

Matrix metalloproteases (MMPs) are enzymes involved in the hydrolysis of proteins and glycoproteins of the extracellular matrix. MMPs are essential for the migration and proliferation of cells through the dense matrix network, throughout embryonic development, and throughout morphogenesis. The first MMP activity discovered was a collagenase in a tadpole's tail undergoing metamorphosis. The active collagen deposition and modifications lead to the morphogenesis of tadpoles into the adult body.
