Osteoprotegerin Ligand Is a Cytokine that Regulates Osteoclast Differentiation and Activation

Reads0
Chats0
TLDR
The effects of OPGL are blocked in vitro and in vivo by OPG, suggesting that OPGl and OPG are key extracellular regulators of osteoclast development.

Osteoclast differentiation and activation

TL;DR: Discovery of the RANK signalling pathway in the osteoclast has provided insight into the mechanisms of osteoporosis and activation of bone resorption, and how hormonal signals impact bone structure and mass.
Journal ArticleDOI

Bone Resorption by Osteoclasts

TL;DR: Osteopetrotic mutants have provided a wealth of information about the genes that regulate the differentiation of osteoclasts and their capacity to resorb bone.
Journal ArticleDOI

Signalling pathways of the TNF superfamily: a double-edged sword.

TL;DR: Two different tumour-necrosis factors, first isolated in 1984, were found to be cytotoxic to tumour cells and to induce tumour regression in mice, and blockers of TNF have been approved for human use in treating TNF-linked autoimmune diseases.
Journal ArticleDOI

Birth and death of bone cells: basic regulatory mechanisms and implications for the pathogenesis and treatment of osteoporosis.

TL;DR: The role and the molecular mechanism of action of regulatory molecules, such as cytokines and hormones, in osteoclast and osteoblast birth and apoptosis are reviewed to review the evidence for the contribution of changes in bone cell birth or death to the pathogenesis of the most common forms of osteoporosis.

Identification and characterization of a new member of the TNF family that induces apoptosis

TL;DR: A novel tumor necrosis factor (TNF) family member has been cloned and characterized, and the TRAIL gene is located on chromosome 3 at position 3q26, which is not close to any other known TNF ligand family members.

A homologue of the TNF receptor and its ligand enhance T-cell growth and dendritic-cell function

TL;DR: RANK and RANKL seem to be important regulators of interactions between T cells and dendritic cells.

Induction of Apoptosis by Apo-2 Ligand, a New Member of the Tumor Necrosis Factor Cytokine Family *

TL;DR: Results suggest that, along with other family members such as Fas/Apo-1 ligand and TNF, Apo-2L may serve as an extracellular signal that triggers programmed cell death.

Crystal structure of the soluble human 55 kd TNF receptor-human TNF beta complex: implications for TNF receptor activation.

TL;DR: The X-ray crystal structure of the complex of the extracellular domain of the human 55 kd tumor necrosis factor (TNF) receptor with human TNF beta has been determined and is likely to be representative of the nerve growth factor (NGF)/TNF receptor family as a whole.
