In Vivo Allergen-Activated Eosinophils Promote Collagen I and Fibronectin Gene Expression in Airway Smooth Muscle Cells via TGF-β1 Signaling Pathway in Asthma

Cross-Sectional Study

Human

2020 Mar 6

This study looks at how a specific pathway in the body affects the production of collagen and other proteins in airway smooth muscle cells.

Stimulation of type II collagen biosynthesis and secretion in bovine chondrocytes cultured with degraded collagen

Cross-Sectional Study

Animal

2003 Mar

When collagen is broken down into smaller pieces, it sends a signal to cartilage cells to make more collagen — like a 'build more!' message — but whole collagen doesn't do this.

The Molecular Interaction of Collagen with Cell Receptors for Biological Function

Narrative Review

This study shows that collagen talks to cells through special receptors, and since collagen peptides are tiny pieces of collagen, they probably do the same thing—telling cells to make more collagen and repair tissues.

Similar Assertions

Collagen-derived peptides function as bioactive signaling molecules that upregulate gene expression involved in de novo collagen synthesis and tissue remodeling.

95%

Collagen peptides specifically stimulate cellular repair signaling pathways in ligaments, cartilage, and other soft tissues, a response not elicited by non-collagenous amino acid blends.

80%

Collagen peptides specifically stimulate cellular repair mechanisms in ligaments, cartilage, and soft tissues, which is not observed with standard amino acid mixtures.

78%

Whether collagen helps heal tissue or makes disease worse depends on what else is around the cell—like other signals, inflammation, or how stiff the tissue is.
