Osteoclast differentiation.
The osteoclast is the primary bone resorbing cell. It is a highly specialized multinucleated cell whose primary function is to help in the control of calcium homeostasis. The osteoclast has been very difficult to study because of its relative inaccessability, low numbers, and fragility when isolated from bone. Recently, techniques have been developed to study the cell biology of the osteoclast ...
متن کاملSphingosine 1-phosphate as a regulator of osteoclast differentiation and osteoclast-osteoblast coupling.
Sphingosine 1-phosphate (S1P), produced by sphingosine kinase (SPHK), acts both by intracellular and extracellular modes. We evaluated the role of SPHK1 and S1P in osteoclastogenesis using bone marrow-derived macrophage (BMM) single and BMM/osteoblast coculture systems. In BMM single cultures, the osteoclastogenic factor receptor activator of NF-kappaB ligand (RANKL) upregulated SPHK1 and incre...
متن کاملSignaling Pathways in Osteoclast Differentiation
Osteoclasts are multinucleated cells of hematopoietic origin that are responsible for the degradation of old bone matrix. Osteoclast differentiation and activity are controlled by two essential cytokines, macrophage colony-stimulating factor (M-CSF) and the receptor activator of nuclear factor-κB ligand (RANKL). M-CSF and RANKL bind to their respective receptors c-Fms and RANK to stimulate oste...
متن کاملOsteoclast differentiation and gene regulation.
Osteoclasts, the bone resorbing cells, play a key role both in normal bone remodeling and in the skeletal osteopenia of arthritis, osteoporosis, periodontal disease and certain malignancies. Osteoclast cellular commitment, differentiation and function depend upon the establishment of specific patterns of gene expression achieved through networks of transcription factors activated by osteoclasto...
متن کاملInterleukin-32 Promotes Osteoclast Differentiation but Not Osteoclast Activation
BACKGROUND Interleukin-32 (IL-32) is a newly described cytokine produced after stimulation by IL-2 or IL-18 and IFN-gamma. IL-32 has the typical properties of a pro-inflammatory mediator and although its role in rheumatoid arthritis has been recently reported its effect on the osteoclastogenesis process remains unclear. METHODOLOGY/PRINCIPAL FINDINGS In the present study, we have shown that I...
