Serum creatine kinase isoenzymes in children with osteogenesis imperfecta [PDF]

, 2017
This study evaluates serum creatine kinase isoenzyme activity in children with osteogenesis imperfecta to determine its usefulness as a biochemical marker during treatment with bisphosphonate.

DC-STAMP is essential for cell–cell fusion in osteoclasts and foreign body giant cells

Journal of Experimental Medicine, 2005
Osteoclasts are bone-resorbing cells that play a pivotal role in bone remodeling. Osteoclasts form large multinuclear giant cells by fusion of mononuclear osteoclasts. How cell fusion is mediated, however, is unclear.

Glucocorticoids Alter Bone Microvascular Barrier via MAPK/Connexin43 Mechanisms

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Osteoporosis induced by Glucocorticoids (GCs) is a common complication of long‐term GC use in patients with inflammatory and autoimmune conditions, often leading to an increased fracture risk. A 3D bicellular endo‐osteo microfluidic platform is developed to explore pathogenic mechanisms underlying GCs‐induced osteoporosis, highlighting a novel MAPK ...

Remodeling Of The Bone Tissue Of Rats Of Different Lines After Melatonin Effect [PDF]

, 2016
The markers of remodeling of bone tissue (BT) were studied after the impact of pharmacologic dose of melatonin (5 mg/kg of the animal body weight) during 28 days for 3-months rats-males of Wistar and SHR lines.

Modelling the anabolic response of bone using a cell population model [PDF]

J Theor Biol 307 (2012) 42-52, 2011
To maintain bone mass during bone remodelling, coupling is required between bone resorption and bone formation. This coordination is achieved by a network of autocrine and paracrine signalling molecules between cells of the osteoclast lineage and cells of the osteoblastic lineage.

Sexual Dimorphism in Osteoclasts [PDF]

Cells, 2020
Osteoclasts are the principal mediators of bone resorption. They form through the fusion of mononuclear precursor cells under the principal influence of the cytokines macrophage colony stimulating factor (M-CSF, aka CSF-1) and receptor activator of NF-κB ligand (RANKL, aka TNFSF11).

Immunosuppressive Cytokine‐Tethered Hydrogel for Treating Rheumatoid Arthritis

Advanced Healthcare Materials, EarlyView.
An injectable hydrogel is developed by chemically tethering IL‐4, an immunosuppressive cytokine, to a hyaluronic acid‐based backbone. The hydrogel reduces joint friction and exerts immunomodulatory effects. In a rheumatoid arthritis (RA) mouse model, it reduced inflammation, preserved cartilage, and promoted anti‐inflammatory immune responses.

Connexin-mimetic peptide Gap 27 decreases osteoclastic activity

BMC Musculoskeletal Disorders, 2001
Background Bone remodelling is dependent on the balance between bone resorbing osteoclasts and bone forming osteoblasts. We have shown previously that osteoclasts contain gap-junctional protein connexin-43 and that a commonly used gap-junctional ...

The Osteoclast—Not Always Guilty [PDF]

Cell Metabolism, 2007
Osteopetrosis is usually regarded as the disease of nonfunctioning osteoclasts, with a consequent accumulation of osseocartilaginous material in the bone marrow. A recent report shows that, in some patients with the rare autosomal recessive form of the disease, the osteoclast defect may be non-cell autonomous, in this case due to a mutation in RANKL ...

A Bio‐Inspired Perspective on Materials Sustainability

Advanced Materials, EarlyView.
This perspective discusses natural materials as inspiration for sustainable engineering designs and the processing of materials. First, circularity, longevity, parsimony, and activity are presented as essential material paradigms. The perspective then uses many examples of natural and technical materials to introduce principles such as oligo ...
