In the present study, we demonstrate delayed-type hypersensitivity (DTH) to homologous type I collagen that cross-reacts with type IV collagen. Mice immunized with native or denatured type I collagens and challenged with these same antigens or native type IV collagen develop a peak DTH response on day 7. Challenge with denatured type IV collagen or collagenase-treated type IV collagen failed to...

Objective: Collagen is one of the main components in connective tissue (CT) and contributes to background toughness beef. It known that living animals, collagen can be degraded remodeled by collagenase matrix metalloproteinases (MMP); however, it unclear if MMP impact CT texture during postmortem aging Therefore, this study aimed understand how activity may degradation beef three different cuts...

Abstract Biological muscles mainly consist of motor proteins that play essential roles and have a hierarchical structure covered with collagen can transmit the tension to bones via tendons. The artificial reconstruction is highly expected from viewpoint engineering biology. Although been developed synthetic biological molecular motors, there considerable gap between components muscles, resultin...

WE HAVE INVESTIGATED WHETHER COLLAGEN QUETERNARY STRUCTURE IS REQUIRED FOR THE PLATELET: collagen interaction. Quaternary structure refers to the assembly of collagen monomers (tropocollagen) into polymers (native-type fibrils). Purified monomeric collagen was prepared from acetic acid extracts of fetal calfskin. Polymeric collagen was prepared by dispersion of bovine Achilles tendon collagen a...

Pelodiscus sinensis, commonly known as the Chinese soft-shelled turtle, possesses abundant collagen, proteins, and amino acids in its shell muscle. sinensis has been historically utilized a valuable traditional medicine. While consume meat of internal visceral organs are typically discarded. The contain components, including 8%-15% collagen 8% blood. This study focused on extracting from organs...

Collagen is a connective tissue protein that mostly produced from cattle and pigs. The use of cows pigs as the manufacture collagen causes disease case, among others are bovine spongiform encephalopathy transmissible disease. One alternative materials in isolation fish skin. purpose this study was to determine effect concentration acetic acid solution on characteristics red snapper by hydroextr...

Tissue Engineering In article number 2207882, Ryan Y. Nguyen, Michael Mak, and co-workers report the fabrication of collagen I hydrogels with topology that mimics complex extracellular matrix architectures in tissues. The generated mesoscopic features, termed islands, are tunable modulate bulk hydrogel mechanical properties. Collagen islands can stem cell behavior differentiation. This method p...

Collagen, the major extracellular matrix protein, is also a membrane protein. Two types of collagen are detected on the normal human fibroblast membrane in culture, type I collagen and a new immunologically and chemically distinct collagen, type M (membrane) collagen. Antibodies to type M collagen elicited complement-mediated cytotoxicity, which could be blocked by pretreatment of the cells wit...
