Matrix metalloproteinases (MMPs), the main extracellular matrix (ECM) enzymes in collagen degradation, as a target for anticancer drugs
This review article describes matrix metalloproteinases (MMPs), the primary enzymes responsible for breaking down collagen in the extracellular matrix. This breakdown process is normal and necessary for tissue remodelin…
Stretch-induced network reconfiguration of collagen fibres in the human facet capsular ligament
The facet capsular ligament in the neck is a common source of chronic pain, often resulting from excessive stretching. This study investigated how the collagen fibers within this ligament reorganize when it is stretched…
Osmotic pressure induced tensile forces in tendon collagen
Researchers investigated the role of water in tendon collagen using a combination of experiments and computer modeling. They found that water is a crucial part of the collagen molecule's structure. When water is removed…
The role of collagen crosslinks in ageing and diabetes - the good, the bad, and the ugly
This narrative review explores how glucose in the body can bind to proteins like collagen, a process called glycation. This process creates crosslinks that can change the mechanical properties and function of connective…
Molecular assembly and mechanical properties of the extracellular matrix: A fibrous protein perspective
This review article examines the extracellular matrix (ECM), the dynamic network of molecules surrounding our cells. The authors focus on fibrous proteins like collagen and elastin, which form the structural backbone of…
The effect of menopause on the skin and other connective tissues
This narrative review examines how menopause and the resulting decline in estrogen affect the body's connective tissues, particularly the skin. Research suggests that skin collagen levels drop significantly following me…
Fascia Research from a Clinician/Scientist’s Perspective
In this perspective piece, a clinician-scientist summarizes exciting areas in fascia research. The article describes the fascial network as a body-wide system that connects individual cells and shares loads with muscles…
Exercise training reduces fibrosis and matrix metalloproteinase dysregulation in the aging rat heart
In this animal study, researchers investigated how exercise affects age-related fibrosis (scarring) in the rat heart. They found that aging was associated with an increase in collagen and a dysregulation of enzymes call…
The extracellular matrix: an active or passive player in fibrosis?
Fibrosis, the excessive buildup of scar tissue, can be understood as a wound healing process that has gone awry. Normally, specialized cells called myofibroblasts help repair tissue and then disappear, but in fibrosis,…
A new lock-step mechanism of matrix remodelling based on subcellular contractile events
Myofibroblasts are cells that contribute to tissue contracture in fibrotic conditions like scarring. This study investigated how these cells contract to remodel tissue. The researchers identified two separate contractio…
