Effects of Bacterial Lysates and Metabolites on Collagen Homeostasis in TNF-α-Challenged Human Dermal Fibroblasts

Microorganisms, 2023
During skin aging, the production of extracellular matrix (ECM) proteins, such as type I collagen, decreases and the synthesis of ECM-degrading matrix metalloproteinases (MMPs) rises, leading to an imbalance in homeostasis and to wrinkle formation.

Microfibrillar structure of type I collagen in situ [PDF]

Proceedings of the National Academy of Sciences, 2006
The fibrous collagens are ubiquitous in animals and form the structural basis of all mammalian connective tissues, including those of the heart, vasculature, skin, cornea, bones, and tendons. However, in comparison with what is known of their production, turnover and physiological structure, very little is understood regarding the ...

Collagen cross‐links: location of pyridinoline in type I collagen

FEBS Letters, 1985
Collagen from bone, dentine and tendon (type I), all of which contain the pyridinoline cross‐link at varying levels, were each digested with CNBr. The resulting peptide mixtures were resolved by gel filtration on A 1.5m agarose and assayed for pyridinoline. The polymeric cross‐linked peptide complex, polyαlCB6 [(1980) Biochem. J.

Regulation of type I collagen genes expression [PDF]

Nephrology Dialysis Transplantation, 2000
Type I collagen is the major component of many extracellular matrices, and its accumulation characterizes most fibrotic processes. It is synthesized by a small number of discrete cell types, including fibroblasts, osteoblasts and odontoblasts. Analysis of transgenic mice harbouring different segments of the promoters of the mouse pro-alpha1 (I) and pro-
