Elastin is Responsible for Tissue Elasticity

Elastin is Responsible for Tissue Elasticity

Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that it will return to its original shape after being stretched or compressed. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column.
Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers and...

Role of Matrix Metalloproteases in Degradation of ECM

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.

Chronic Inflammation: Introduction

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...

Extracellular Matrix

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...

The Effect of Aging on Tissues

The Effect of Aging on Tissues

Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Summary

Elastin fragments, called elastokines, act as repair signals by attracting immune cells and promoting cell growth. However, chronic exposure contributes to inflammation and age-related diseases like abdominal aortic aneurysms.

Area of Science:

Biochemistry
Cell Biology
Pathology

Background:

Elastin degradation by elastases produces bioactive fragments called elastokines.
Elastokines possess cytokine-like properties, influencing tissue repair and inflammation.

Purpose of the Study:

To explore the multifaceted roles of elastokines in biological processes.
To investigate the contribution of elastokines to age-related diseases, particularly abdominal aortic aneurysms (AAAs).
To hypothesize the role of elastokines in cancer development, specifically melanoma.

Main Methods:

Analysis of elastokine properties, including chemotaxis, proliferation, and angiogenesis.
Investigation of elastokine-receptor interactions (S-Gal) and downstream effects.
Examination of elastokine involvement in age-related arterial diseases and cancer progression.

Main Results:

Elastokines exhibit potent chemotactic, proliferative, and proangiogenic activities.
Chronic elastokine exposure contributes to inflamm-aging and stimulates matrix metalloproteinase expression.
Elastokines may promote Th-1 polarization, arterial calcification, and melanoma progression.

Conclusions:

Elastokines are key mediators in tissue repair, inflammation, and age-related pathologies.
A novel elastokine theory for AAA progression is proposed.
Elastokines may create a pro-cancerous microenvironment, influencing melanoma vertical growth.
